Infleuce of dietary levels of vitamin E and selenium on tissue and blood parameters in pigs. (1/17862)

Eighteen barrows approximately three weeks of age were used in a 3 X 3 factorial arrangement to investigate the effect of level of supplemental vitamin E and selenium on tissue and blood parameters. Tissue selenium concentrations increased in a quadratic manner with increased selenium intake with kidney tissue containing considerably greater concentrations than liver, heart or muscle. Supplementation of the diet caused a three-fold increase in serum selenium within the first week with a slight tendency to further increases in subsequent weeks. Serum vitamin E of unsupplemented pigs declined by fifty percent during the experiment, whereas supplemental vitamin E resulted in increased serum vitamin E. There was a considerable viration in percent peroxide hemolysis. Correlation of -0.63 between percent peroxide hemolysis and vitamin E intake and -0.85 between percent peroxide hemolysis and serum vitamin E were observed.  (+info)

Pathological changes in chickens, ducks and turkeys fed high levels of rapeseed oil. (2/17862)

Rations containing 25% of either regular rapeseed oil (36% erucic acid), Oro rapeseed oil (1.9% erucic acid), soybean oil or a mixture of lard and corn oil were fed to chickens, ducks and turkeys. The regular rapeseed oil ration caused growth depression, increased feed conversion and anemia in all species. All the ducks and some of the chickens fed the regular rapeseed oil ration died. These dead birds were affected with hydropericardium and ascites. No deaths in the turkeys could be attributed to the regular rapeseed oil ration but some turkeys fed this ration had degenerative foci characterized by infiltrations of histiocytic and giant cells in the myocardium. Severe fatty change in the heart, skeletal muscles, spleen and kidney was found at an early age in all birds fed the regular rapeseed oil ration. Less severe fatty change but no other lesions were found in birds fed the Oro rapeseed oil and soybean oil rations.  (+info)

In vitro effects of 2,4-dichlorophenoxy acetic acid (2,4-D) on bovine cells. (3/17862)

Bovine fetal muscle cells were exposed to culture media containing 2 mg and 20 mg per liter of 2,4-dichlorophenoxy acetic acid (2,4-D) for varying intervals to determine the in vitro response of mammalian cells to this compound. The concentrations of 2,4-D used were comparable to those used in spray programmes although the residues normally found in pasture are much lower since 2,4-D is rapidly degraded under field conditions. Untreated and treated cultures were analyzed for total cell count, mitotic index and the percentages of differentiating and degenerating cells. The response of cultures to treatment was similar irrespective of the concentrations of 2,4-D used although in higher concentrations there was an initial drop in mitotic index. Other changes noted in treated cultures included an increase in differentiating and degenerating cells compared to those in control. The mitotic cells in treated cultures exhibited unipolar and tripolar spindles and a variety of other abnormalities including malorientation of the mitotic apparatus in relation to the axis of the cell. Myoblasts in initial stages of myogenesis were noted to be in mitosis in treated cultures suggesting that 2,4-D may have a stimulatory effect on myoblasts which in normal myogenesis are in post mitotic stage.  (+info)

Synthesis and kinetic evaluation of 4-deoxymaltopentaose and 4-deoxymaltohexaose as inhibitors of muscle and potato alpha-glucan phosphorylases. (4/17862)

alpha-Glucan phosphorylases degrade linear or branched oligosaccharides via a glycosyl transfer reaction, occurring with retention of configuration, to generate alpha-glucose-1-phosphate (G1P). We report here the chemoenzymic synthesis of two incompetent oligosaccharide substrate analogues, 4-deoxymaltohexaose (4DG6) and 4-deoxymaltopentaose (4DG5), for use in probing this mechanism. A kinetic analysis of the interactions of 4DG5 and 4DG6 with both muscle and potato phosphorylases was completed to provide insight into the nature of the binding mode of oligosaccharide to phosphorylase. The 4-deoxy-oligosaccharides bind competitively with maltopentaose and non-competitively with respect to orthophosphate or G1P in each case, indicating binding in the oligosaccharide binding site. Further, 4DG5 and 4DG6 were found to bind to potato and muscle phosphorylases some 10-40-fold tighter than does maltopentaose. Similar increases in affinity as a consequence of 4-deoxygenation were observed previously for the binding of polymeric glycogen analogues to rabbit muscle phosphorylase [Withers (1990) Carbohydr. Res. 196, 61-73].  (+info)

Metallothionein-null mice absorb less Zn from an egg-white diet, but a similar amount from solutions, although with altered intertissue Zn distribution. (5/17862)

The influence of metallothionein (MT) on Zn transfer into non-gut tissues was investigated in MT-null (MT-/-) and normal (MT+/+) mice 4 h after oral gavage of aqueous 65ZnSO4solution at doses of 154, 385, 770 and 1540 nmol Zn per mouse. Zn transfer was not significantly different between MT+/+ and MT-/- mice and was directly proportional to the oral dose (slope = 0.127, r = 0.991; 0. 146, r = 0.994, respectively). Blood 65Zn and plasma Zn concentrations increased progressively in MT-/- mice at doses >154 nmol Zn, reaching levels of 2.4% of oral dose and 60 micromol/L, respectively, at the 1540 nmol Zn dose. The corresponding values for MT+/+ mice were approximately half, 1.0% and 29 micromol/L. Intergenotypic differences were found in tissue distribution of 65Zn within the body; MT-/- mice had higher 65Zn levels in muscle, skin, heart and brain, whereas MT+/+ mice retained progressively more Zn in the liver, in conjunction with a linear increase in hepatic MT up to the highest Zn dose. MT induction in the small intestine reached its maximum at an oral dose of 385 nmol Zn and did not differ at higher doses. Absorption of a 770 nmol 65Zn dose from a solid egg-white diet was only one fourth (MT+/+) and one eighth (MT-/-) of the Zn absorption from the same dose of 65Zn in aqueous solution. MT+/+ mice had greater (P < 0.05) Zn absorption from the egg-white diet than did MT-/- mice, indicating that gut MT confers an absorptive advantage, but only when Zn is incorporated into solid food.  (+info)

The effect of denervation and dystrophy on the adaptation of sarcomere number to the functional length of the muscle in young and adult mice. (6/17862)

In young animals the elongation of the limb bones increases the functional lengths of the muscles. In adult animals the functional length of a muscle can be increased by immobilizing it in the lengthened position. In both cases the muscle adapts by adding on more sarcomeres in series. The role of the nerve supply in this adaptation has been investigated using denervated muscles and muscles from dystrophic animals where there is thought to be an abnormality of the nerve supply. Postnatal sarcomere addition in denervated muscles falls short of that of controls. Although this might mean that the nerve supply is necessary for normal addition of sarcomeres, it is just as likely that there is a change in gait resulting from denervation, which affects the sarcomere number. Sarcomere number in fully grown mice is not affected by denervation, nor is the ability of the muscle to adapt to immobilization in the lengthened position. This is true for fast-twitch as well as slow-twitch muscles. In dystrophic muscles postnatal sarcomere addition is normal, although the presence of a few short fibres in the muscle may mean that some muscle fibres cannot adapt to an increase in the functional length of the muscle accompanying bone growth. Adult dystrophic muscle is capable of adapting to immobilization in the lengthened position. However, although the total number of additional sarcomeres is the same as in normal immobilized muscle, they are added on at a slower rate. The experiments show that although denervated and dystrophic muscle fibres are in a state of atrophy they are still capable of adding on sarcomeres in series when the functional length of the muscle is increased. It would appear that the mechanism which enables the muscle to respond in this way to an increased functional length does not involve the nerve supply. This work was supported by a grant from the National Fund for Research into Crippling Diseases.  (+info)

Gamma-Actinin, a new regulatory protein from rabbit skeletal muscle. I. Purification and characterization. (7/17862)

A new regulatory protein which we have designated as gamma-actinin has been isolated from native thin filaments of rabbit skeletal muscle. Depolymerized native thin filaments were fractionated by salting out with ammonium sulfate, and the precipitates obtained at 40--60% ammonium sulfate saturation were further subjected to DEAE-Sephadex and Sephadex G-200 column chromatography. The purified gamma-actinin was shown to have a chain weight of 35,000 daltons and had a strong inhibitory action on the polymerization of G-actin. The results of amino acid analysis indicated a unique amino acid composition of gamma-actinin as compared with other structural proteins of muscle. Non-polar and neutral amino acid residues were abundant. One cysteine residue was contained per one molecule of gamma-actinin and played a critical role in the maintenance of the inhibitory activity. Pelleting of gamma-actinin with F-actin showed that gamma-actinin binds to F-action.  (+info)

Connectin, an elastic protein from myofibrils. (8/17862)

The elastic protein isolated from myofibrils of chicken skeletal muscle was compared with extracellular non-collagenous reticulin prepared from chicken liver and skeletal muscle. The amino acid compositions of these proteins were similar except that their contents of Phe, Leu, Cys/2, and Hyp were different. The impregnations of the elastic protein and reticulin with silver were also different. The reticulin was not at all elastic. It also differed from reticulin in solubility and antigenicity. It is proposed to call the intracellular elastic protein connectin.  (+info)

This ability to stretch and still maintain contractility is important in organs like the intestines and urinary bladder. Muscle fibers have pointed ends and exhibit fusiform or spindle shape. One of the common examples of striated muscle is Bicep. 1. Their examples can be given as bicep muscles, tricep muscles, rectus muscles of abdomen, quadriceps, hamstring muscles of thigh and muscles of the shoulder girdle, etc. These muscles are found in the walls of the internal organs such … Find more Tamil words at! Its is defined as a bundle or band of fibrous tissue in animals that has the capability of producing movement by contraction and relaxation. Striated muscles are attached to the skeleton via tendons, but non-striated muscle does not have tendons, they are present in internal organs. Muscles that contain striated muscle fibers are called striated muscle and muscles that contain non-striated muscle fibers are called non-striated muscles. Striated Muscle: Non-Striated Muscle: ...
Home » Muscle. muscle (Science: anatomy) tissue specialised for contraction. See twitch muscle, catch muscle: cardiac muscle (heart muscle) is a striated but involuntary muscle responsible for the pumping activity of the vertebrate heart. The individual muscle cells are joined through a junctional complex known as the intercalated disc and are not fused together into multinucleate structures as they are in skeletal muscle. Skeletal muscle is a rather non-specific term usually applied to the striated muscle of vertebrates that is under voluntary control. The muscle fibres are syncytial and contain myofibrils, tandem arrays of sarcomeres. Smooth muscle is muscle tissue in vertebrates made up from long tapering cells that may be anything from 20-500m long. Smooth muscle is generally involuntary and differs from striated muscle in the much higher actin/myosin ratio, the absence of conspicuous sarcomeres and the ability to contract to a much smaller fraction of its resting length. Smooth muscle ...
As pointed out by others is the concept of resilient relaxation (fang song). My understanding of what is involved here physiologically is that you want the muscles used for movement - the fast twitch muscles which are typically located towards the exterior of the muscle groups - to be as relaxed as possible while supporting the structure/postures with the slow twitch muscles located more internally. Thus you get steel wrapped in cotton, and this seems to be what is trained in either standing meditation or holding postures from the form for lengthy periods of time. Holding postures for long periods of time tire out the fast twitch muscles until they are forced to relax while the slow twitch muscles can continue to hold ones structure/posture (or take over from the fast twitch muscles if they were being relied upon) and get built up. The more that the body is trained to use the slow twitch muscles for supporting its structure and the more relaxed the fast twitch muscles can become, then the more ...
It is now common, even in the health club arenas, to hear the terms stabilizing exercise, and core muscles. But what do these terms really mean, what are such muscles, and why are such exercises and muscle groups so important?. MUSCLES HAVE SPECIFIC ROLES. When we look at our skeletal muscle system, we know that not all muscles are the same in their function and physiological makeup. Some muscles are located deep and close to our joints, have predominantly slow twitch type muscle fibers, are often short muscles, and can contract for prolonged periods and have some tension most of the time. These are endurance type muscles, whose primary function is to ensure that the joints can move in a mechanically normal fashion. They thereby provide stability to the joints. These are the stabilizing, or true core muscles in our body.. An authority on the muscular system, Vladimir Janda, M.D. referred to these muscles as the tonic muscles. They are there to provide support, not to move our limbs or ...
Instrumentation has been developed to detect rapidly the polarization of tryptophan fluorescence from single muscle fibers in rigor, relaxation, and contraction. The polarization parameter (P⊥) obtained by exiciting the muscle tryptophans with light polarized perpendicular to the long axis of the muscle fiber had a magnitude P⊥ (relaxation) , P⊥ (contraction) , P⊥ (rigor) for the three types of muscle fibers examined (glycerinated rabbit psoas, glycerinated dorsal longitudinal flight muscle of Lethocerus americanus, and live semitendinosus of Rana pipiens). P⊥ from single psoas fibers in rigor was found to increase as the sarcomere length increased but in relaxed fibers P⊥ was independent of sarcomere length. After rigor, pyrophosphate produced little or no change in P⊥, but following an adenosine triphosphate (ATP)-containing solution, pyrophosphate produced a value of P⊥ that fell between the contraction and relaxation values. Sinusoidal or square wave oscillations of the ...

One objective of the red-white muscle experiment was simply to test the function of the newly assembled porcine microarray, from which two gene lists were generated (Tables 1 and 2). Genes that were expected to be differentially expressed and genes that were novel were found on each list. The microarray results validated our prior hypothesis of differential gene expression in red and white muscles, thus demonstrating the functional integrity of our newly constructed microarray. One of the well established distinguishing features of red muscle is its relatively high oxidative phosphorylation capacity, reflected by an abundance of mitochondria in red muscles. It is reassuring that genes from the mitochondrial genome were well represented in the red muscle pool of differentially expressed genes (Table 1). White muscles comprise predominantly more fast-glycolytic fibres than red muscles. Our findings were consistent with expectations, in that most of the 45 clones selected as more highly expressed ...
The muscles of the head perform a wide variety of functions and come in a variety of shapes and sizes. Some of these muscles are the smallest muscles of the body, others have the highest ratio of neuron to muscle fibers in the body, and others can generate more force per unit area than any other muscle. They perform functions that range from chewing food to manipulating speech, from moving the eyes to creating the wide variety of facial expressions, and they even modify the strength of the sound waves approaching the inner ear. These interesting muscles arise from two distinct developmental programs in the embryo - the branchial, or pharyngeal, arches and the head somites. Each of these embryonic tissues has an associated cranial nerve. As the embryonic muscle mass develops to its final postnatal group of muscles, each of these muscles is innervated by the same nerve that innervated the embryonic muscle primordium. While, the embryonic somites are the principal source of skeletal muscle tissue ...
A muscle biopsy is a procedure used to diagnose diseases involving muscle tissue. Tissue and cells from a specific muscle are removed and viewed microscopically. The procedure requires only a small piece of tissue to be removed from the designated muscle.. The tissue sample is obtained by inserting a biopsy needle into the muscle. If a larger sample is required, your doctor may make an incision in the skin (open biopsy) and remove a larger section of muscle.. The muscle selected for the biopsy depends on the location of symptoms which may include pain or weakness. The muscles often selected for sampling are the bicep (upper arm muscle), deltoid (shoulder muscle), or quadriceps (thigh muscle).. A related procedure that may be used to diagnose neuromuscular problems is electromyography (EMG). EMG measures the electrical activity of muscle during rest, slight contraction, and forceful contraction. Please see this procedure for additional information.. ...

The muscular system is the major force-producing tissue of animals. In particular, the skeletal muscles enable precise body movements of invertebrates and vertebrates. For these accurate movements, each muscle must be properly connected to the skeleton. This is achieved by the attachment of both ends of the muscle fiber to tendons, which in turn connect to the skeleton. In large animals, it is often hundreds of fibers that are packed into muscle fiber bundles that run parallel to the long axis of the muscle. Thus, muscle is a highly polar tissue, which harbors a defined contraction axis between both tendon attachments (Hill and Olson, 2012).. The sarcomere is the contractile unit of each muscle fiber (Clark et al., 2002; Gautel and Djinovic-Carugo, 2016). Each sarcomere is symmetrically organized between two Z-discs, which cross-link antiparallel polar actin filaments, also called thin filaments. The centrally located thick filaments comprise bipolar myosin filaments. These thick filaments are ...

This finally brings us to the real hero of your life story- cardiac muscle. Like skeletal muscle, cardiac muscle is striated and like the other muscle in your body is primarily powered by mitochondria. The cardiac muscles, however, have as much as 10 times the density of mitochondria as your other muscles, at about 35% of the volume of your cardiac muscle.. It should also be noted that individual muscle cells in the heart actually do get regular rest thanks to how the heart beat actually works, which well get into in the Bonus Fact in a bit. But the net result is that about 60%-70% of your life a given part of your heart is actually in a resting state.. Combining these micro-rests with the extreme amount of mitochondria and a large amount of oxygen from the hearts awesome blood supply, this allows your heart all the ATP it needs to not get tired, assuming youre not in an extreme state of starvation or doing some extreme form of exercise for extended periods well beyond your normal fitness ...
Muscle is a soft tissue found in most animals. Muscle cells contain protein filaments of actin and myosin that slide past one another, producing a contraction that changes both the length and the shape of the cell. Muscles function to produce force and motion . They are primarily responsible for maintaining and changing posture , locomotion , as well as movement of internal organs , such as the contraction of the heart and the movement of food through the digestive system via peristalsis . Muscle tissues are derived from the mesodermal layer of embryonic germ cells in a process known as myogenesis . There are three types of muscle, skeletal or striated, cardiac , and smooth . Muscle action can be classified as being either voluntary or involuntary. Cardiac and smooth muscles contract without conscious thought and are termed involuntary, whereas the skeletal muscles contract upon command. Skeletal muscles in turn can be divided into fast and slow twitch fibers. Muscles are predominantly powered by the

Muscle differentiation is a complex process finely tuned by the interplay of positive and negative factors. Although key positive regulators have been identified, there is rather little evidence of restraining molecules that can control the time and place of muscle differentiation. Identification of such molecules and analysis of their function during muscle differentiation is therefore necessary to gain new insight into the molecular events that regulate this process. My work centred on a gene, Dmeso17A that was identified in the Taylor laboratory in a screen to isolate novel genes specifically expressed in muscle progenitors in Drosophila (Taylor, 2000). Its pattern of expression suggested it could be an inhibitor of muscle development. My aim was to analyse both the role and mechanism of action of Dmeso17A. Dmeso17A expression rapidly declines as muscle differentiation starts, but persists in the adult muscle precursors that remain undifferentiated at this stage. Using the GAL4/UAS system ...
021b1c530e2e11ef4617e7ab780b4170 Whats the strongest muscle in the human body? That question is actually difficult to answer. The human body has three different kinds of muscles (cardiac, skeletal, and smooth) and there are hundreds of muscles in the body. Each muscle works to help make the body strong as a whole. However, there are a few muscles that do more work than many of the others. Eye Muscles The muscles in your eyes, particularly the muscles on the outside of your eyes do a lot of work. These external muscles help your eye adjust its position so it can keep a steady gaze. They can move over 10,000 times in an hour. Thats a lot of work! Gluteus Maximus The gluteus maximus is a large muscle. In fact, its the largest in your body. It helps to keep your body upright and controls your posture. It also works against gravity, which means it has to be very strong. Heart Many people think the heart is your strongest muscle because it works the hardest. Your heart pumps blood 24 hours
RONNIE COLEMAN: Every exercise I do is a favorite isolation exercise, but its also a favorite mass-building exercise. I dont distinguish between the two. My purpose as a bodybuilder is to ensure that every muscle has received its optimum amount of training by the time Ive finished my workout. That, to me, is isolation.. Somewhere along the way, bodybuilders began to define isolation in what I call negative terms; i.e., the removal of all supporting muscles from the movement, so that only a single target muscle is allowed to contract. If other muscles are involved, they either prevent the target muscle from doing the work or they cause the body to fatigue before the target muscle is fully exercised.. I prefer a more positive approach. Instead of trying to isolate a muscle, I think in terms of trying to isolate maximum forces into a muscle. With concentration and proper control of the movement, I command supporting muscles to make the target muscle work even harder. Here are some of my favorite ...

Here are my questions (I have several). 1) Are the fast twitch muscle fibers dominant or recessive as opposed to the slow?. 2) Are people of mixed race/greatest genetic diversity in their background, tend to be the best athletes and the healthiest in general?. Allow me to clarify the first point: Obviously no one in the world is either 100% fast twitch or 100% slow twitch. Lets put this another way: (and Im just using random numbers here that are probably unrealistic, bear with me). Lets say someone who is 80% fast twitch and 20% slow twitch has a baby with someone who is precisely the other way. Would the child develop more of the fast twitch or more of the slow twitch?. ...
Compound exercises may be the key to maximizing your muscle-building results and getting the most out of your workouts. These exercises use many muscle groups in the same lift. A great example is a squat, which uses both the muscles in your legs and your core muscles for one movement.. If you are trying to build up muscle mass, be sure to get plenty of protein in your diet. Protein is a chief building block of muscle, and consuming not enough of it may cause you to have less muscles, which kills the reason of trying to bulk up. You might need to eat over 100 grams of protein per day depending on your weight.. It can be beneficial to train opposite muscles during the same workout. Examples are the muscles in your back and the muscles in your stomach, or the quads and the hamstrings. This gives one muscle group a break while you work the opposite and also ensures that you dont train unevenly and create muscle imbalances. This allows you to engage in shorter, more intense workouts without risking ...
Many people use their body too seldom and too little varied. Everyday life is for most people affected by a lot of sitting. That often causes pain and tenderness in muscles, tendons and joints. The nerves that set the muscles in motion will die if they are not used. Thus the muscles also die. Its ancient wisdom that pains in muscles while exercising will disappear with more exercise. We know that the muscles repair themselves when they are being used. The muscles also become bigger and stronger. New muscle cells are formed from the muscles stem cells and existing ones grow.. Weight loss is another advantage of working out. The number of mitochondria, the cells power plants, increases when we exercise. This accelerates the energy production in the muscle cells, thus we burn more fat. The best way to strengthen muscles and at the same time burn more fat is to use heavy weights and take long pauses between the different exercises. Using lighter weights and shorter breaks helps improving your ...
Groups of muscles in the human body form the muscular system and because many of these muscles are attached to bones, this system is often referred to, along with the skeletal system, as the musculoskeletal system.. There are 639 muscles in the human body which fall into one of three categories - striated, smooth, and cardiac.. Striated muscles are the skeletal muscles such as the ones in the arms, legs, back, and chest.. Smooth muscles are the involuntary muscles and are found in the cardiovascular, digestive, and urinary systems. For instance, the walls of blood vessels contain smooth muscle as do the bladder and intestines.. While the function of the heart muscle is to pump blood to and from the heart and the rest of the body, the purpose of skeletal muscles is to provide movement, posture, balance, strength, and body heat.. ...
Do you have big muscles? Even if you dont lift weights or play sports, you might be surprised to learn just how strong some of your muscles are. But which of your many muscles is the strongest?. Actually, theres no easy answer to that question. It all really depends upon how you define strong. Many different muscles might be considered strongest, depending upon exactly what kind of strength youre talking about. Different muscles will have to fight it out to see which one can truly claim to be the strongest. How appropriate!. Lets get one common misconception out of the way to start. From time to time, youll see lists of interesting facts about the human body. Many times these lists will claim that the tongue is the strongest muscle in the human body. This is incorrect for a couple of reasons.. First, the tongue isnt a single muscle. Its actually made up of eight different muscles. Second, while very strong and flexible, the tongue cannot lay a valid claim to be the strongest muscle in ...

Cooperation. It is interesting to note that, although muscles give us independence, they also convey the idea of cooperation. Body movement is achieved by muscles contracting and releasing. Muscles work in what is known as antagonistic pairs to achieve two-way movements. As an example: to lift the forearm, the bicep muscle contracts and the tricep muscle relaxes. To push the forearm down, the tricep contracts and the bicep relaxes. Biceps and triceps are an antagonistic pair of muscles and can achieve a change of direction with power and strength. So muscles - and Muscle Driver - are about working together to achieve things in the real world. Cooperation is the word and cooperation with opposites is the notion. If two antagonistic muscles contract together they will fight each other, greatly restricting their ability to function. This happens in life: sometimes people seem to be fighting themselves, beating themselves up. Muscle Driver Infoceutical can help balance this tendency. ...
Our muscles basically do two things - contract and relax. Of course, this alone is not enough. Just from contracting and relaxing your biceps, you wont build any muscle. That is why for centuries, various tools have been used to increase resistance and thus tension in the muscle. Ones own body weight, dumbbells, machines, resistance bands, etc. all increase muscle tension and improve the build-up of muscle.. Time under Tension. It is not enough for the muscle to be under contraction tension for a short amount of time. The actual time under tension is crucial for building muscle. This is the reason why the weights in classical resistance training are usually not only lifted once, but several times to repeatedly cause muscular contraction. From experience, a good effect for the build-up of muscle is achieved by 8-12 repetitions in 3 sets per exercise, which equals a time under tension of 1 to 3 minutes per muscle group, depending on scope and progress of the exercise programme.. bodyforming ...
1. The endings of the motor nerves in striped muscle remain on the outside of the sarcolemma. Aside from the surfaces of contact of muscle and nerve fibre, the end fibres are covered down to their tips with the sheath of Schwann and are provided with nuclei. The precise condition of things at the places of contact of muscle and nerve is an unsolved problem of histology.. 2. The ivy-like or festooned arrangement of motor nerves in the frogs muscle has been misinterpreted. Properly interpreted it demonstrates that the nerve fibres that are to influence the muscle fibre are not naked and that they need not be end fibres. It shows that mere contact between muscle fibre and nerve fibre is all that is necessary.. 3. The sheath of Henle in the frog and in the smaller muscle fibres of the snake is open, thus permitting escape of the cerebrospinal fluid.. 4. In other animals Henles sheath extends over the end fibres of the motor nerve and the cells lining it envelop the end fibrils. I find that the ...
1. The structure and distribution of the components of striated muscle cells vary with the species and with the specialization of muscle fiber function. 2. There appear to be two, easily distinguishable, general categories of striated muscle structure. A. High frequency muscle (represented by flight muscle of higher insects and hummingbird, and cicada tympanal muscle) is characterized by widely spaced, non-branching fibrils of large diameter and short period, little endoplasmic reticulum, and large quantities of large mitochondria (low fibril-sarcoplasm ratio). This structure is correlated with heavy tracheolization or vascularization, high oxidative activity, and dark color as compared with other muscles of the same species. B. Low frequency muscle is characterized, in general, by high fibril-sarcoplasm ratio, relatively long period, few mitochondria increasing with activity and decreasing with absolute power of the fiber. Oxidative capacity and color are proportional to the quantity of ...
Muscle growth is the primary objective of meat animal livestock producers and represents a major source of amino acids and energy within the animal. Endogenous and exogenous factors that impinge on muscle cell development may influence the animal throughout its life cycle. In the adult animal, treatment with hormones, such as anabolic steroids or insulin, can affect muscle metabolism. Attempting to determine a compounds effects on muscle cell development and metabolism can be obscured in animal trials, since other organs and tissues are altering the environment. Muscle cell culture provides a research tool to determine the direct effects of a specific compound. There are several advantages to cell culture use. First, the cells can be grown as a pure culture. Ideally, the cells are of the same type. Secondly, the culture environment can be controlled. The environment includes the atmosphere, temperature, pH, and the available nutrients. Finally, the sample processing can be simple and rapid. Cell

Crdiac muscle (heart muscle) is involuntary striated muscle that is found in the walls and histological foundation of the heart, specifically the myocardium. Cardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle. These three types of muscle all form in the process of myogenesis. The cells that constitute cardiac muscle, called cardiomyocytes or myocardiocytes, contain only three nuclei ...
FLAT VS. FAT. Remember when I said some fat is a good thing? When fat is stored interstitially (with- in the muscle fibers), it creates both a more full muscle but also an additional leverage point for muscles to push against, thereby increasing both size and strength. This is great for big muscle bellies like your quads, chest, and lats, but not so good for thinner muscles like your abs. Furthermore, in smaller, thinner muscles like the abs, which are separated by a ligamentous tissue, those separations dont keep their hard end points as both the water you consume and the fat you build like to set up camp between your muscles. As you are also likely aware, as you consume more carbs along with water, your muscles will fill up, making you look great if timed properly. No doubt you also know that after a period of time, the water (and carbs) will seep out and fill up the space between muscle bellies making you look ...

Movement is made more flexible with joints. Here, ligaments hold bones together. They limit the movement thus preventing dislocation. The joints move due to the force of muscles acting on them. Muscles are attached to bones by tendons that are made of collagen fibres. When a muscle contracts, the tendon and its attached bone are pulled towards the contracting muscle. Many joints work due to the action of antagonistic muscles; one set causes the joint to move one way, the other set causes it to return. When one muscle in the pair is contracting, the other is relaxing (not stretching). An example of this arrangement is the elbow joint controlled by the biceps and triceps muscle. There are three types of muscle, skeletal, cardiac and smooth... Skeletal: Cardiac: Smooth: Function: Locomotion Pumping blood through heart Line blood vessels, digestive tract (peristalsis), uterus, etc. Cells: Striated Specialised striated Unstriated Control of contraction: Multiple Muscle Systems [4196443] - The picture on the front cover of this book depicts a young man pulling a fishnet, a task of practical relevance for many centuries. It is a complex task, involving load transmission throughout the body, intricate balance, and eye head-hand coordination. The quest toward understanding how we perform such tasks
Muscles and their associated tendons come in a wide variety of shapes and sizes. The different shapes and sizes coupled with the relationships they form with one another, with the skeleton, and at the joints they cross create the large variety of musculoskeletal action that is such an integral part of the bodys function. It is also from the differences in shape and size that muscles derive their names. When the early anatomists began naming muscles they used a logical, descriptive approach. Understanding the logic behind the name can help you learn about the muscle. The characteristic features of a muscle name include adjectives and genitives that modify the noun muscle. Keep in mind that the full name of any muscle of the body begins with musculus, a masculine noun. The English language has dropped this from common usage and allows the adjective and the genitive that describe the muscle to stand alone as the English noun. For example, musculus latissimus dorsi becomes the latissimus dorsi ...
This type of muscle tissue is found only in the heart.. The heart must beat from the end of the third week of embryonic development, right through until the time we die.. If individual cardiac muscle cells are removed from the heart and kept alive in a glass culture dish containing a suitable nutrient medium, they continue to contract rhythmically.. Like skeletal muscle cells, cardiac muscle cells have a striated appearance, but unlike skeletal muscle cells they have a branching structure.. However, in the living person the intrinsic rhythm of the individual cardiac cells is over-ridden by the nerve supply to the heart. In this way, the rate of contraction of the heart is adjusted to match the needs of the person - whether asleep or dashing for a bus.. Most of us cannot consciously change the rate of our heart beat (although some individuals have been able to train themselves to achieve this), so we say that cardiac muscle is under involuntary control. ...
What is Protein? It is a well-known fact that protein is essential for muscle development. Protein is macronutrient. It is composed of amino acids which are the building blocks of muscles. Amino acids are responsible for muscle growth, repair, and maintaining muscle tissues. Hence, body development and muscle growth are impossible without protein.. Protein is also made up of carbon, hydrogen, oxygen, and nitrogen. Adding protein in your diet supports an anabolic state. It is a condition wherein the body has well-balanced nitrogen levels. That is why eating a sufficient amount of protein is a crucial requirement for successful muscle growth.. How does it Work? Albeit eating protein is significant for body development, it does necessarily mean youll grow muscles by eating this macronutrient alone. Having a balanced diet with foods rich in protein, complex carbohydrates, vitamins, and healthy fats, partnered with regular exercises is the key.. The muscles are made of two types of proteins called ...
This electron microscopic study deals with the structure of the Z disc of frogs skeletal muscle, with special regard to the I filaments-whether they pass through the Z disc or terminate at it. In most longitudinal sections the I filaments terminate as rod-like projections on either side of the Z disc, one I filament on one side lying between two I filaments on the opposite side. This indicates that the I filaments are not continuous through the Z disc. The rod-like projections are often seen to consist of filaments (denoted as Z filaments) which meet at an angle.. In cross-sections through the Z region the I filaments and Z filaments form tetragonal patterns. The I filaments are situated in the corners of the squares; the oblique Z filaments form the sides of squares. The tetragonal pattern formed by the Z filaments is rotated 45 degrees with respect to the tetragons formed by the I filaments on both sides of Z. This structural arrangement is interpreted to indicate that each I filament on one ...
A goal of biomechanics and motor control is to understand the design of the human musculoskeletal system. Here we investigated human functional morphology by making predictions about the muscle volume distribution that is optimal for a specific motor task. We examined a well-studied and relatively simple human movement, vertical jumping. We investigated how high a human could jump if muscle volume were optimized for jumping, and determined how the optimal parameters improve performance. We used a four-link inverted pendulum model of human vertical jumping actuated by Hill-type muscles, that well-approximates skilled human performance. We optimized muscle volume by allowing the cross-sectional area and muscle fiber optimum length to be changed for each muscle, while maintaining constant total muscle volume. We observed, perhaps surprisingly, that the reference model, based on human anthropometric data, is relatively good for vertical jumping; it achieves 90% of the jump height predicted by a model with

One of the biggest myths in the exercise world is that you can turn fat into muscle. Fat and muscle are two entirely different tissues. Fat is made up of triglycerides and muscle is made up of proteins. There is no mechanism to turn triglycerides into protein. Turning fat into muscle is a different way of saying, I want to burn fat and build muscle.. Now that you know what turning fat into muscle really is, you can understand how to accomplish it. First, you will need to start burning the fat your body has stored by reducing your calorie intake and increasing your exercise.. You can figure out how many calories you burn by using the Calorie Calculator. To burn fat, you need to eat less than this so that your body can start using its fat stores for energy. Over time you will lose weight and your body fat percentage will decrease.. To build muscle you need to engage in resistance or strength training. Training your muscles involves pushing them farther than you did your previous work in order to ...
Some Essential elements may aid in Lean muscle growth aiding recovery and fat loss. Some of these elements have been clinically proven for over 20 years. They also may help strengthen bones and tendons and enhance cellular metabolism.. These elements that prevent muscle breakdown essentially have NO Hormone altering effects (testosterone or Oestrogen) as they naturally occur. No muscle wastage means it can be said to have a PURE anabolic effect.. There are many elements that may help save muscle to promote a good metabolism. Muscle is our metabolism and we need to protect it from wastage to maintain its optimal functioning. Muscle is also essential and has been proven to aid heart patients, as loss of muscle means a lack of support for the lymphatic system and cardiovascular detriment.. Essential elements that may help prevent muscle breakdown and decrease chances of becoming catabolic may include:.

EMS follows the same principle of muscle training. Training 8 major muscle group i.e legs, gluteus, lower back, upper back, middle back, chest, abdominal and arms at a same time the amount of calories you burn will be more. Normal workout takes 48 hours to recover but in EMS training your body takes 4 to 5 days to recover. So in those 4 to 5 days your body is still burning calories to recover your muscle.. If EMS is done on regular basis, it helps to reduce excess body fat, gain muscle and thereby increasing bodys metabolism. EMS training stimulates all large muscle groups with high intensity at the same time. This strengthens the core muscles and thereby help in building body mass with proper toning of body , So we get a proper sculpted, In-shape body.. ...
Purpose. The aim of this study was to quantitatively investigate the effects of muscle strengthening in a vertical squat jump based on a neuro-musculo-skeletal model and a forward dynamics simulation. Methods. During simulation trials, 16 major muscle groups of the lower extremities were gradually strengthened up to 20%. Results. Complex yet systematic deviations in body kinematics, kinetics and the neural control pattern were observed as a result of gradual muscle strengthening. Conclusions. Based on the generated results it was concluded that: (i) the pattern of kinematical changes depends on which muscles are strengthened, while the magnitude of the changes depends on how much the muscles are strengthened. (ii) Adjustment of muscle coordination, in some cases, can be performed without adjustment of neural control. (iii) The adjustment of neural control is done in an adaptive manner. (iv) Inter-segmental coordination is further altered if a smaller number of muscles are strengthened. (v) The ...

  • But here's why you should bring them back: The drill activates your fast-twitch muscle fibers, which will stimulate fat loss and improve your power, explains Jack. (
  • On the fourth day, following IRB, the dogs were placed under general anaesthesia, and the diaphragm was perfused via the internal mammary artery with a low molecular weight fluorescent tracer (Procion orange, FW = 631), to which normal muscle fibers are impermeable. (
  • Also, the muscles that were not massaged had more damaged muscle fibers and more white blood cells , which can indicate inflammation. (
  • Thousands, or even tens of thousands, of small fibers make up each muscle. (
  • These are your skeletal muscles - sometimes called striated (say: STRY-ay-tud) muscle because the light and dark parts of the muscle fibers make them look striped (striated is a fancy word meaning striped). (
  • In the presence of dystrophin, muscle fibers support each other, but when this protein is absent, contraction causes injury. (
  • And, most importantly, these muscle-like fibers are simple to make and recycle. (
  • In a new paper published in Nature Nanotechnology ("Nanostructured block copolymer muscles"), the researchers showed that these fibers, which they initially discovered while working on another project, are more efficient, flexible and able to handle increased strain compared to what's out there today. (
  • Muscles contain fibers that contract (get smaller), allowing you to perform lots of different movements. (
  • Like all other skeletal muscles in the body, neck muscles contain lots of tiny, elastic fibers that allow the muscles to contract. (
  • Skeletal muscle fibers are red and white, so the muscles look striated (striped or streaked). (
  • It's the result of overstretching or tearing the muscle fibers. (
  • This article describes a case of unilateral masseter muscle hypertrophy, where the surgical resection of the muscle fibers in an intraoral approach and a osteotomy with a reciprocating saw were performed in the mandibular angle region. (

  • This course was developed to improve Clinician understanding of Respiratory Muscle Weakness (RMW), an extremely prevalent issue that is often undertreated. (
  • She is a leader in her field and strives for great outcomes with each client impacted by Respiratory Muscle Weakness. (
  • Her area of expertise is Respiratory Muscle Weakness and Cardiopulmonary conditions. (
  • Muscle weakness is linked to impaired mobility and mortality in older persons. (
  • Doctors were seeing a fair number of patients who complained about muscle aching, and some patients complained about muscle weakness, but the literature didn't support that there actually was this problem. (
  • It treats a group of rare genetic disorders called spinal muscular atrophies (SMAs) that cause loss of nerve cells that control skeletal muscles (muscles that allow us to move) leading to weakness. (
  • Muscular dystrophies are a group of inherited diseases that cause muscle wasting and weakness. (
  • Recover from a tough gym day with these exercises to help sore muscles. (
  • So, if you're looking to train the same muscles required in the overhead press but want to vary your workouts, you might be wondering if there are other exercises you can do. (
  • Exercises that target the small muscles in your shoulders and upper back, such as scapular retraction and prone lateral raise , can help you decrease injuries and allow you to perform the overhead press more efficiently. (
  • Since these are also used by gymnasts, muscle rings are great for emphasizing upper body strength, but are a bit more limited in lower body exercises and not as beginner-friendly as suspension trainers are. (
  • Knowing that the vastus muscles are primarily involved in knee extension and stabilization, we can also understand that exercises including these actions are important for strengthening them. (
  • Compound exercises work more than one muscle group at a time. (
  • Muscle cramps. (
  • (
  • Also called muscle cramps , muscle spasms occur when a muscle contracts and can't relax. (
  • It also helps reduce fatigue and muscle cramps. (
  • Runners typically experience calf pain in the form of strains, which can range from mild stretching or complete tearing of a muscle, or cramps, which occur when a muscle is stuck in a state of contraction, says Chris Johnson, a physical therapist in Seattle, Wash., who works with runners and triathletes. (
  • If you are suffering from day-to-day pain such as muscle aches, dental pain, menstrual cramps, and more, here's how THC could offer some relief. (
  • The mesh outstrips its traditional competitors in more ways than one - not only is it supremely malleable, but it also maintains a constant temperature for as long as your sore muscles may need it to do so. (
  • What are the best essential oils for sore muscles? (
  • Some of the biggest and most powerful muscles are your calf and thigh muscles. (
  • ANOVA results indicated that EMG data for nine of 10 thigh muscles were affected by an interaction between posture and angular position of the load lifted (p50.001). (
  • Left thigh muscles showed the opposite pattern. (
  • EMG activity for the majority of thigh muscles was affected by the size of the base of support provided by different postures, with lower EMG activity observed with a larger base of support and increased activity in postures where base of support was reduced (p50.05). (
  • These thigh muscles support us not only in sports, but are essential for daily activities like climbing the stairs and getting up from a chair. (
  • Ten apprentice jockeys and 48 horses were instrumented with heart-rate monitors, accelerometers, and a surface electromyography BodySuit (recording 8 muscle groups: quadriceps, hamstrings, gluteal, lower back, obliques, abdominal, trapezial, and pectoral) that recorded continuously while riding their normal morning track-work. (
  • Surface electromyography data from three neck muscles were collected. (
  • Electromyography signal analysis of knee flexor and extensor muscles in potential knee musculoskeletal disorders during roofing. (
  • Using surface electromyography (EMG), the authors collected maximum normalized EMG signals from the above-mentioned muscles of seven subjects who mimicked a shingle installation task with kneeling on a slope-configurable wooden platform. (
  • These muscles help to make up the musculoskeletal (say: mus-kyuh-low-SKEL-uh-tul) system - the combination of your muscles and your skeleton, or bones. (
  • Your neck muscles are part of a complex musculoskeletal system (soft tissues and bones) that connect the base of your skull to your torso. (
  • This study assessed the effects of kneeling posture and roof slope on the peak activations of knee flexor (biceps femoris and semitendinosus) and extensor (rectus femoris, vastus lateralis, and vastus medialis) muscles that are potential risk indicators of knee musculoskeletal disorders (MSD) in shingle installation. (
  • BOSTON - Becker (BMD) and Duchenne muscle dystrophy (DMD) progress largely from irreversible contraction-induced injury of skeletal muscles, making the very positive interim results of an early-phase trial with a drug that prevents these injuries worth attention. (
  • It's not only required for strong bones and teeth, but it is also vital for muscle contraction and energy metabolism. (
  • Magnesium plays a vital part in muscle contraction and helps to boost energy levels. (
  • It had various ill-defined names in the past including tension headache, stress headache, muscle contraction headache, psychomyogenic headache, ordinary headache, and psychogenic headache. (
  • The more likely cause of these headaches is believed now to be abnormal neuronal sensitivity and pain facilitation, not abnormal muscle contraction. (
  • Headache is not related directly to muscle contraction, and possible hypersensitivity of neurons in the trigeminal nucleus caudalis has been suggested. (
  • Although vasomotor responses to hypoxia are modulated by endothelial factors and autonomic innervation , it is well established that arterial smooth muscle cells contain an acute O2 sensing system capable of detecting changes in O2 tension and to signal membrane ion channels , which in turn regulate cytosolic Ca2+ levels and myocyte contraction. (
  • Vastus intermedius is the deepest of the four quadriceps muscles, located in the middle of the thigh, beneath rectus femoris and in between vastus lateralis and vastus medialis . (
  • In recent years, a slanted muscle was discovered between vastus lateralis and vastus intermedius . (
  • that control muscles that move the eyes and eyelids are particularly affected, although other nerves can also be involved. (
  • Abnormal growth of cranial nerves impairs extraocular muscle function and leads to the characteristic features of CFEOM, including restricted eye movement and droopy eyelids. (
  • Mutations likely eliminate the function of the PHOX2A protein, which prevents the normal development of these cranial nerves and impairs control of the extraocular muscles. (
  • Pushing his shoulder forward, the joystick signals a computer carried on his wheelchair, which then sends a series of timed electrical pulses to eight platinum electrodes implanted next to nerves feeding the muscles that close his hand. (
  • Signals come from the brain, down through the spinal cord, out through the peripheral nerves and into the muscles," said Dr. Paul F. Pasquina, a physician and chairman of the Department of Physical Medicine and Rehabilitation at the Uniformed Services University of the Health Sciences and director of the university's Center for Rehabilitation Sciences Research. (
  • Different combinations of muscles enervated by cranial nerves III-VII and X were involved. (
  • SMN1 helps the body make an important protein that keeps the nerves that control muscle movement healthy. (
  • It helps muscles and nerves work properly by changing the SMN2 gene product to make more of the SMN protein than it usually would. (

  • Flexor carpi ulnaris is one of the wrist flexor muscles of the front (palmar) aspect of the forearm. (
  • Flexor Carpi Radialis is a wrist muscle which also crosses the elbow joint and so is also a weak elbow flexor. (
  • Except for the vastus medialis muscle of the right knee, significant increase in the peak normalized EMG was observed for all flexor and extensor muscles during shingle installation on the sloped roof surface. (
  • Significant interaction between the slope and posture was observed for the flexor muscles of the right knee and vastus medialis muscle of the left knee. (
  • Flexor carpi radialis is the first muscle medial to your finger at the level of the apex of the antecubital fossa (where brachioradialis and the muscle converge) and is superficial at that point. (
  • The European Journal of Applied Physiology study, which assessed muscle use at different points in the pedal stroke, concluded that "During pedaling, an optimization of quadriceps and hamstring muscle recruitment is desirable for producing power at the pedal. (
  • To assess quadriceps and hamstring muscle demands in these postures, nine participants performed lateral load transfers in kneeling and squatting postures, during which electromyographic (EMG) data were collected. (
  • Arthritis can cause warmth, tenderness, and swelling in the joints and muscles. (
  • Physical demands, such as lifting and working in awkward postures, place additional stress on your muscles and joints. (

  • It has been suggested that age-related sarcopenia is due to: i) elevated basal-fasted rates of muscle protein breakdown, ii) a reduction in basal muscle protein synthesis (MPS), or iii) a combination of the two factors. (
  • However, basal rates of muscle protein synthesis and breakdown are unchanged with advancing healthy age. (
  • Ageing muscle is less sensitive to lower doses of amino acids than the young and may require higher quantities of protein to acutely stimulate equivalent muscle protein synthesis above rest and accrue muscle proteins. (
  • With regards to physical activity, lower, than previously realized, intensity high-volume resistance exercise can stimulate a robust muscle protein synthetic response similar to traditional high-intensity low volume training, which may be beneficial for older adults. (
  • Resistance exercise combined with amino acid ingestion elicits the greatest anabolic response and may assist elderly in producing a 'youthful' muscle protein synthetic response provided sufficient protein is ingested following exercise. (
  • Although the etiology of sarcopenia is multifaceted, [ 8 ] in the context of this review we will focus, primarily, on the contribution of alterations in muscle protein turnover (muscle protein synthesis and breakdown) to muscle wasting in the elderly. (
  • Our understanding of the contribution of muscle protein turnover to sarcopenia has shifted from a thesis in which basal muscle protein metabolism was thought to be compromised in the elderly, to a new paradigm whereby the synthetic responsiveness of muscle protein synthesis to anabolic stimuli, such as food and contractile loading, is blunted with aging. (
  • As such, we're searching for various protein-rich, quality food varieties that form muscle and not just a super-sized burger with fries, correct? (
  • In this case, it's a protein called "dystrophin" that keeps muscle membranes stable and strong. (
  • Tendons are cords made of tough tissue, and they work as special connector pieces between bone and muscle. (
  • Whiplash usually involves muscles, ligaments and tendons. (
  • Nature's choice is to provide chemical power for natural actuators like muscles. (
  • Growth Surge contains ingredients proven to enhance recovery and muscle growth, including creatine monohydrate for greater anabolic endurance , betaine anhydrous to promote cellular hydration , and L-carnitine. (
  • Instead, it appears that the muscles of the elderly are resistant to normally robust anabolic stimuli such as amino acids and resistance exercise. (
  • To take anabolic steroids for muscle building has gotten to be just about a form. (
  • That is the reason sports people and weight lifters love to take anabolic steroids to build muscle and improve physical quality. (
  • Utilization of anabolic steroids by muscle heads and sportsmen to improve their execution is unlegal. (
  • At least one study, in the Scandinavian Journal of Rehabilitation Medicine (opens in new tab) , has found that being attached to the pedals changes the way the rectus femoris is activated: A study in the journal found that that muscle was activated 20° earlier in the pedal stroke when riders used toe clips. (
  • As the name suggests ( quad is the Latin word for four ), we have four quadriceps muscles- rectus femoris and three vastus muscles. (
  • All of these muscles get worked with dumbbell lunges. (
  • In any case, what is fundamentally significant for thin folks and young ladies is to spread your calories out over the course of the day to guarantee a steady stock of energy to your muscles and a predictable metabolic rate, and eating a great deal of food sources that form muscle will assist you with doing that. (
  • Acute oxygen sensing by vascular smooth muscle cells. (
  • These muscles include the heart, the muscles used during breathing, and all the limb muscles. (
  • The findings hint that it may be possible someday to introduce other genes into adult muscle to address conditions besides muscular dystrophy. (
  • Some muscular dystrophies are caused by mutations in genes that make important muscle proteins. (
  • One promising approach uses an injection of small, harmless viruses to deliver therapeutic dystrophin-producing genes directly into cells in the muscle. (
  • Our new work identifies for the first time a method where a new dystrophin gene can be delivered, using a safe and simple method, to all of the affected muscles of a mouse with muscular dystrophy," said Dr. Jeffrey S. Chamberlain, professor of neurology and director of the Muscular Dystrophy Cooperative Research Center at the University of Washington School of Medicine in Seattle. (
  • Chamberlain and colleagues in the Muscular Dystrophy Cooperative Research Center are gathering data to seek regulatory approval for a limited trial in humans to determine the safety of a very small amount of the vector in human muscle. (
  • This agent was shown to prevent the muscle injury caused by lack of dystrophin in animal models of muscular dystrophy and is now showing the same effect in humans. (
  • In the past, various mechanisms including vascular, muscular (ie, constant overcontraction of scalp muscles), and psychogenic factors were suggested. (
  • By giving one single injection of this AAV vector carrying a mini-dystrophin gene into the bloodstream, we are able to deliver therapeutic levels of dystrophin to every skeletal and cardiac muscle of an adult, dystrophic mouse," Chamberlain said. (
  • She explained that dystrophin in muscles connects contractile proteins to membranes and surrounding matrix. (
  • There's no cure for DMD, but there are treatments that can help with the symptoms, including gene-based therapies that help the muscles make more dystrophin. (
  • The protruding electrodes were connected to a computer in Peckham's lab, which fired off signals to the muscles in various configurations. (
  • All it is is a MIDI device playing the instruments and using electrical pulses through the electrodes to tense the muscles. (
  • In his work with Peckham, Jatich saw wires threaded through his wrist with a needle in a trial-and-error hunt to provoke movement in the correct muscle groups. (
  • You'll find smooth muscles at work behind the scenes in your eyes, too. (
  • In practice, this mostly means distributing less total work to maintenance muscles and more relative work to those muscles you're aggressively trying to improve. (
  • Pushups work some of the same muscles as the overhead press, including the pectorals, triceps, and shoulders. (
  • This paper examines the EMG responses of knee extensors/flexors to lifting in these postures, discusses the impact of posture and kneepads on muscle recruitment and explores the implications for work in such postures. (
  • If you have something like the TRX already, there's not a whole lot of reason to also get muscle rings, unless you want to work on gymnastic-specific movements. (
  • But if you know what a few of these words mean, you can work out more about the muscle. (
  • What Muscles Does Lifting Dumbbells Work? (
  • Not only are they inexpensive compared to machines, but they also cause you to work stabilizing muscles while focusing on a primary muscle, which helps speed up your progress. (
  • You work these muscles by doing a motion called elbow flexion. (
