Unstriated and unstriped muscle, one of the muscles of the internal organs, blood vessels, hair follicles, etc. Contractile elements are elongated, usually spindle-shaped cells with centrally located nuclei. Smooth muscle fibers are bound together into sheets or bundles by reticular fibers and frequently elastic nets are also abundant. (From Stedman, 25th ed)
Muscle Fibers, Skeletal
Large, multinucleate single cells, either cylindrical or prismatic in shape, that form the basic unit of SKELETAL MUSCLE. They consist of MYOFIBRILS enclosed within and attached to the SARCOLEMMA. They are derived from the fusion of skeletal myoblasts (MYOBLASTS, SKELETAL) into a syncytium, followed by differentiation.
A state arrived at through prolonged and strong contraction of a muscle. Studies in athletes during prolonged submaximal exercise have shown that muscle fatigue increases in almost direct proportion to the rate of muscle glycogen depletion. Muscle fatigue in short-term maximal exercise is associated with oxygen lack and an increased level of blood and muscle lactic acid, and an accompanying increase in hydrogen-ion concentration in the exercised muscle.
Muscle Fibers, Fast-Twitch
Muscle Fibers, Slow-Twitch
Myocytes, Smooth Muscle
Skeletal muscle structures that function as the MECHANORECEPTORS responsible for the stretch or myotactic reflex (REFLEX, STRETCH). They are composed of a bundle of encapsulated SKELETAL MUSCLE FIBERS, i.e., the intrafusal fibers (nuclear bag 1 fibers, nuclear bag 2 fibers, and nuclear chain fibers) innervated by SENSORY NEURONS.
A vague complaint of debility, fatigue, or exhaustion attributable to weakness of various muscles. The weakness can be characterized as subacute or chronic, often progressive, and is a manifestation of many muscle and neuromuscular diseases. (From Wyngaarden et al., Cecil Textbook of Medicine, 19th ed, p2251)
Mature contractile cells, commonly known as myocytes, that form one of three kinds of muscle. The three types of muscle cells are skeletal (MUSCLE FIBERS, SKELETAL), cardiac (MYOCYTES, CARDIAC), and smooth (MYOCYTES, SMOOTH MUSCLE). They are derived from embryonic (precursor) muscle cells called MYOBLASTS.
Satellite Cells, Skeletal Muscle
A powerful flexor of the thigh at the hip joint (psoas major) and a weak flexor of the trunk and lumbar spinal column (psoas minor). Psoas is derived from the Greek "psoa", the plural meaning "muscles of the loin". It is a common site of infection manifesting as abscess (PSOAS ABSCESS). The psoas muscles and their fibers are also used frequently in experiments in muscle physiology.
Myosin Heavy Chains
A basic element found in nearly all organized tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
The muscles of the PHARYNX are voluntary muscles arranged in two layers. The external circular layer consists of three constrictors (superior, middle, and inferior). The internal longitudinal layer consists of the palatopharyngeus, the salpingopharyngeus, and the stylopharyngeus. During swallowing, the outer layer constricts the pharyngeal wall and the inner layer elevates pharynx and LARYNX.
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
Filamentous proteins that are the main constituent of the thin filaments of muscle fibers. The filaments (known also as filamentous or F-actin) can be dissociated into their globular subunits; each subunit is composed of a single polypeptide 375 amino acids long. This is known as globular or G-actin. In conjunction with MYOSINS, actin is responsible for the contraction and relaxation of muscle.
Mice, Inbred mdx
A strain of mice arising from a spontaneous MUTATION (mdx) in inbred C57BL mice. This mutation is X chromosome-linked and produces viable homozygous animals that lack the muscle protein DYSTROPHIN, have high serum levels of muscle ENZYMES, and possess histological lesions similar to human MUSCULAR DYSTROPHY. The histological features, linkage, and map position of mdx make these mice a worthy animal model of DUCHENNE MUSCULAR DYSTROPHY.
Muscle Stretching Exercises
Exercises that stretch the muscle fibers with the aim to increase muscle-tendon FLEXIBILITY, improve RANGE OF MOTION or musculoskeletal function, and prevent injuries. There are various types of stretching techniques including active, passive (relaxed), static, dynamic (gentle), ballistic (forced), isometric, and others.
Continuous involuntary sustained muscle contraction which is often a manifestation of BASAL GANGLIA DISEASES. When an affected muscle is passively stretched, the degree of resistance remains constant regardless of the rate at which the muscle is stretched. This feature helps to distinguish rigidity from MUSCLE SPASTICITY. (From Adams et al., Principles of Neurology, 6th ed, p73)
A muscle protein localized in surface membranes which is the product of the Duchenne/Becker muscular dystrophy gene. Individuals with Duchenne muscular dystrophy usually lack dystrophin completely while those with Becker muscular dystrophy have dystrophin of an altered size. It shares features with other cytoskeletal proteins such as SPECTRIN and alpha-actinin but the precise function of dystrophin is not clear. One possible role might be to preserve the integrity and alignment of the plasma membrane to the myofibrils during muscle contraction and relaxation. MW 400 kDa.
The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.
A 51-amino acid pancreatic hormone that plays a major role in the regulation of glucose metabolism, directly by suppressing endogenous glucose production (GLYCOGENOLYSIS; GLUCONEOGENESIS) and indirectly by suppressing GLUCAGON secretion and LIPOLYSIS. Native insulin is a globular protein comprised of a zinc-coordinated hexamer. Each insulin monomer containing two chains, A (21 residues) and B (30 residues), linked by two disulfide bonds. Insulin is used as a drug to control insulin-dependent diabetes mellitus (DIABETES MELLITUS, TYPE 1).
Gene Expression Regulation
The voltage differences across a membrane. For cellular membranes they are computed by subtracting the voltage measured outside the membrane from the voltage measured inside the membrane. They result from differences of inside versus outside concentration of potassium, sodium, chloride, and other ions across cells' or ORGANELLES membranes. For excitable cells, the resting membrane potentials range between -30 and -100 millivolts. Physical, chemical, or electrical stimuli can make a membrane potential more negative (hyperpolarization), or less negative (depolarization).
The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago. (From Walker's Mammals of the World, 6th ed, p801)
A transferase that catalyzes formation of PHOSPHOCREATINE from ATP + CREATINE. The reaction stores ATP energy as phosphocreatine. Three cytoplasmic ISOENZYMES have been identified in human tissues: the MM type from SKELETAL MUSCLE, the MB type from myocardial tissue and the BB type from nervous tissue as well as a mitochondrial isoenzyme. Macro-creatine kinase refers to creatine kinase complexed with other serum proteins.
Muscle Relaxants, Central
A heterogeneous group of drugs used to produce muscle relaxation, excepting the neuromuscular blocking agents. They have their primary clinical and therapeutic uses in the treatment of muscle spasm and immobility associated with strains, sprains, and injuries of the back and, to a lesser degree, injuries to the neck. They have been used also for the treatment of a variety of clinical conditions that have in common only the presence of skeletal muscle hyperactivity, for example, the muscle spasms that can occur in MULTIPLE SCLEROSIS. (From Smith and Reynard, Textbook of Pharmacology, 1991, p358)
A form of muscle hypertonia associated with upper MOTOR NEURON DISEASE. Resistance to passive stretch of a spastic muscle results in minimal initial resistance (a "free interval") followed by an incremental increase in muscle tone. Tone increases in proportion to the velocity of stretch. Spasticity is usually accompanied by HYPERREFLEXIA and variable degrees of MUSCLE WEAKNESS. (From Adams et al., Principles of Neurology, 6th ed, p54)
Muscular Dystrophy, Duchenne
An X-linked recessive muscle disease caused by an inability to synthesize DYSTROPHIN, which is involved with maintaining the integrity of the sarcolemma. Muscle fibers undergo a process that features degeneration and regeneration. Clinical manifestations include proximal weakness in the first few years of life, pseudohypertrophy, cardiomyopathy (see MYOCARDIAL DISEASES), and an increased incidence of impaired mentation. Becker muscular dystrophy is a closely related condition featuring a later onset of disease (usually adolescence) and a slowly progressive course. (Adams et al., Principles of Neurology, 6th ed, p1415)
Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Muscle Strength Dynamometer
Cell surface proteins that bind acetylcholine with high affinity and trigger intracellular changes influencing the behavior of cells. Cholinergic receptors are divided into two major classes, muscarinic and nicotinic, based originally on their affinity for nicotine and muscarine. Each group is further subdivided based on pharmacology, location, mode of action, and/or molecular biology.
The act, process, or result of passing from one place or position to another. It differs from LOCOMOTION in that locomotion is restricted to the passing of the whole body from one place to another, while movement encompasses both locomotion but also a change of the position of the whole body or any of its parts. Movement may be used with reference to humans, vertebrate and invertebrate animals, and microorganisms. Differentiate also from MOTOR ACTIVITY, movement associated with behavior.
Dose-Response Relationship, Drug
Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.
Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.
An element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells. Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE.
Amino Acid Sequence
A methylxanthine naturally occurring in some beverages and also used as a pharmacological agent. Caffeine's most notable pharmacological effect is as a central nervous system stimulant, increasing alertness and producing agitation. It also relaxes SMOOTH MUSCLE, stimulates CARDIAC MUSCLE, stimulates DIURESIS, and appears to be useful in the treatment of some types of headache. Several cellular actions of caffeine have been observed, but it is not entirely clear how each contributes to its pharmacological profile. Among the most important are inhibition of cyclic nucleotide PHOSPHODIESTERASES, antagonism of ADENOSINE RECEPTORS, and modulation of intracellular calcium handling.

Myogenic Regulatory Factors
A family of muscle-specific transcription factors which bind to DNA in control regions and thus regulate myogenesis. All members of this family contain a conserved helix-loop-helix motif which is homologous to the myc family proteins. These factors are only found in skeletal muscle. Members include the myoD protein (MYOD PROTEIN); MYOGENIN; myf-5, and myf-6 (also called MRF4 or herculin).
Glucose Transporter Type 4
A glucose transport protein found in mature MUSCLE CELLS and ADIPOCYTES. It promotes transport of glucose from the BLOOD into target TISSUES. The inactive form of the protein is localized in CYTOPLASMIC VESICLES. In response to INSULIN, it is translocated to the PLASMA MEMBRANE where it facilitates glucose uptake.

Analysis of Variance
Specialized connective tissue composed of fat cells (ADIPOCYTES). It is the site of stored FATS, usually in the form of TRIGLYCERIDES. In mammals, there are two types of adipose tissue, the WHITE FAT and the BROWN FAT. Their relative distributions vary in different species with most adipose tissue being white.
Accumulation of a drug or chemical substance in various organs (including those not relevant to its pharmacologic or therapeutic action). This distribution depends on the blood flow or perfusion rate of the organ, the ability of the drug to penetrate organ membranes, tissue specificity, protein binding. The distribution is usually expressed as tissue to plasma ratios.
Ryanodine Receptor Calcium Release Channel
A tetrameric calcium release channel in the SARCOPLASMIC RETICULUM membrane of SMOOTH MUSCLE CELLS, acting oppositely to SARCOPLASMIC RETICULUM CALCIUM-TRANSPORTING ATPASES. It is important in skeletal and cardiac excitation-contraction coupling and studied by using RYANODINE. Abnormalities are implicated in CARDIAC ARRHYTHMIAS and MUSCULAR DISEASES.
Muscular Disorders, Atrophic
Disorders characterized by an abnormal reduction in muscle volume due to a decrease in the size or number of muscle fibers. Atrophy may result from diseases intrinsic to muscle tissue (e.g., MUSCULAR DYSTROPHY) or secondary to PERIPHERAL NERVOUS SYSTEM DISEASES that impair innervation to muscle tissue (e.g., MUSCULAR ATROPHY, SPINAL).
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.

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.

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)

non striated muscle meaning in tamil
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 wordhippo.com! 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: ...
Muscle - Biology-Online Dictionary
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 ...
Yang Family Tai Chi Discussion Board • View topic - peng-jin?
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 ...
Stabilizing Muscles and Joint Instability | Mossberg Physical Therapy
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 ...
Polarization of Tryptophan Fluorescence from Single Striated Muscle Fibers | JGP
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 ...

Development of a porcine skeletal muscle cDNA microarray: analysis of differential transcript expression in phenotypically...
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 ...
anatomyEXPERT - Muscles of the head - Structure Detail
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 ...
NewYork-Presbyterian Queens - Muscle Biopsy
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.. ...

Mechanical tension and spontaneous muscle twitching precede the formation of cross-striated muscle in vivo | Development
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 ...
Muscle Biopsy - Health Encyclopedia - University of Rochester Medical Center
A muscle biopsy is a procedure used to diagnose diseases involving muscle tissue. Your healthcare provider will remove tissue and cells from a specific muscle and view them under a microscope. Your provider will only need to remove a small piece of tissue from the muscle. Your healthcare provider takes the tissue sample by inserting a biopsy needle into your muscle. If a larger sample is required, your healthcare provider may make an incision in your skin (open biopsy) and remove a larger section of muscle. The muscle selected for your 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). ...
Why Doesnt the Heart Get Tired and Need to Rest Like Other Muscles?
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

British Library EThOS: Dmeso17A : a novel inhibitor of Drosophila muscle differentiation
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 ...
Strongest Muscle in the Human Body - Group of Questions
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
What Is Isolation? | Muscle & Fitness
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 ...

genetics - question about fast/slow muscle twitch fibers - Biology Stack Exchange
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?. ...
Suggestions For Beginners And Pros For Building Muscle - Kulcha Fari
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 ...
RECOVERY - take care of your muscles | EQOLOGY
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 ...
muscles Archives - Kates Daily Bread
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.. ...
What Is the Strongest Muscle in Your Body? | Wonderopolis
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 ...

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 ...
THE NERVES OF THE CAPILLARIES, WITH REMARKS ON NERVE-ENDINGS IN MUSCLE | JEM
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 ...
COMPARATIVE CYTOPHYSIOLOGY OF STRIATED MUSCLE WITH SPECIAL REFERENCE TO THE ROLE OF THE ENDOPLASMIC RETICULUM | Journal of...
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 ...
Use of Cell Culture to Study Muscle Growth in Beef Cattle by Timothy Woods, Carol Smith et al.
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

Winter Mass Part 1 | Muscle & Fitness
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 ...
Muscles and Movement | S-cool, the revision website
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...

anatomyEXPERT - Muscles - developmental approach - Structure Detail
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 ...
Headstart in Biology - cardiac muscle
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. ...
Why Protein is Important for Muscle Building? - Erin Radio Homepage
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 ...
THE ULTRASTRUCTURE OF THE Z DISC IN SKELETAL MUSCLE | JCB
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 ...
Optimizing the Distribution of Leg Muscles for Vertical Jumping. by Jeremy D Wong, Maarten F Bobbert et al.
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

How do I turn fat into muscle?
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 ...

Electronic Muscle Stimulation (EMS)
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.. ...
The Effects of Muscle Strengthening on Neuro-Musculo-Skeletal Dynamics in A Squat Jump: A Simulation Study - Human Movement -...
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 ...

Muscle Can Be a Life Saver
By Editorial Staff. For everyone out there who thinks cardio is the only exercise you need, think again. Particularly as we get older, muscle is an essential component of healthy living. Heres why.. As we get older, we naturally lose muscle if we dont maintain / build it: up to 3-5 percent loss per decade, beginning as young as age 30 or so. Muscle is also harder to develop as we age, even if you stay physically active. Thats two strikes against us. The third strike, if we let it happen, is where the real problem lies: Lack of muscle can increase the risk of injury, falls, weight gain and more; and even reduce our overall life expectancy.. Yes, muscle can truly be a life saver, and recent research proves it. A study in Medicine & Science in Sports & Exercise put the theory to the test by evaluating 4,449 participants ages 50 years and older from the National Health and Nutrition Examination Survey. Low muscle strength increased the risk of all-cause mortality (risk of death) ... regardless of ...
Calcium pumping ATPase muscle enzyme - Stock Image A605/0157 - Science Photo Library
Calcium pumping ATPase enzyme. Computer model of the ATPase enzyme that pumps calcium in and out of muscle cells and controls muscle contractions. The name ATPase refers to this enzymes ability to break up the ATP (adenosine triphosphate) molecule and release energy. This ATPase uses the energy to pump calcium ions in and out of muscle cells, and it is found in muscle cell membranes. Calcium ions are central to the process of muscle contraction. Enzymes are catalysts and so promote reactions and are not used up. They are also proteins. Proteins are long chains of amino acids. This protein has around 1000 amino acids and about 15,000 atoms. - Stock Image A605/0157
