Short-term synchronization of intercostal motoneurone activity. (1/190)

1. The hypothesis is advanced that the joint occurrence of unitary excitatory post-synaptic potentials e.p.s.p.s) evoked in motoneurones by branches of common stem pre-synaptic fibres causes short-term synchronization of their discharge during the rising phases of the unitary e.p.s.p.s. 2. This hypothesis was tested using the pre- and post-stimulus time (PPST) histogram to detect synchronized firing among groups of intercostal motoneurones discharging in response to their natural synaptic drives. 3. Motor nerve action potentials were recorded monophasically from nerve filaments of the external intercostal muscles of anaesthetized, paralysed cats maintained on artificial ventilation. 4. Computer methods were used to measure peak spike amplitude, spike amplitude, spike interval and filament identification for simultaneous recordings from four filaments. The spike amplitude histograms were derived for each filament and groups of spikes were selected for analysis. 5. With spikes of one group designated as 'stimuli' (occurring at zero time) and those of a second as 'response' the PPST histogram was computed with different time bin widths. 6. With bin widths of 100 and 10 msec the central respiratory periodicity was apparent in the PPST histogram. With 1.0 msec bins the PPST histogram showed a narrow central peak extending to +/- 3.0 msec at its base. This 'short-term synchronization' supports the hypothesis of joint firing due to common presynaptic connectivity. 7. It was shown that detection of short-term synchronization was critically dependent on a sufficient quantity of data but that provided a simple criterion of adequate counts per bin in the PPST histogram was met, short-term synchronization could be detected between intercostal motoneurones of the same and adjacent segments.  (+info)

Pattern of expiratory muscle activation during lower thoracic spinal cord stimulation. (2/190)

Large positive airway pressures (Paws) can be generated by lower thoracic spinal cord stimulation (SCS), which may be a useful method of restoring cough in spinal cord-injured patients. Optimal electrode placement, however, requires an assessment of the pattern of current spread during SCS. Studies were performed in anesthetized dogs to assess the pattern of expiratory muscle recruitment during SCS applied at different spinal cord levels. A multicontact stimulating electrode was positioned over the surface of the lower thoracic and upper lumbar spinal cord. Recording electromyographic electrodes were placed at several locations in the abdominal and internal intercostal muscles. SCS was applied at each lead, in separate trials, with single shocks of 0.2-ms duration. The intensity of stimulation was adjusted to determine the threshold for development of the compound action potential at each electrode lead. The values of current threshold for activation of each muscle formed parabolas with minimum values at specific spinal root levels. The slopes of the parabolas were relatively steep, indicating that the threshold for muscle activation increases rapidly at more cephalad and caudal sites. These results were compared with the effectiveness of SCS (50 Hz; train duration, 1-2 s) at different spinal cord levels to produce changes in Paw. Stimulation at the T9 and T10 spinal cord level resulted in the largest positive Paws with a single lead. At these sites, threshold values for activation of the internal intercostal (7-11th interspaces) upper portions of external oblique, rectus abdominis, and transversus abdominis were near their minimum. Threshold values for activation of the caudal portions of the abdominal muscles were high (>50 mA). Our results indicate that 1) activation of the more cephalad portions of the abdominal muscles is more important than activation of caudal regions in the generation of positive Paws and 2) it is not possible to achieve complete activation of the expiratory muscles with a single electrode lead by using modest current levels. In support of this latter conclusion, a two-electrode lead system results in more uniform expiratory muscle activation and significantly greater changes in Paw.  (+info)

Respiratory mechanical advantage of the canine external and internal intercostal muscles. (3/190)

1. The current conventional view of intercostal muscle actions is based on the theory of Hamberger (1749) and maintains that as a result of the orientation of the muscle fibres, the external intercostals have an inspiratory action on the lung and the internal interosseous intercostals have an expiratory action. This notion, however, remains unproved. 2. In the present studies, the respiratory actions of the canine external and internal intercostal muscles were evaluated by applying the Maxwell reciprocity theorem. Thus the effects of passive inflation on the changes in length of the muscles throughout the rib cage were assessed, and the distributions of muscle mass were determined. The fractional changes in muscle length during inflation were then multiplied by muscle mass and maximum active stress (3.0 kg cm-2) to evaluate the potential effects of the muscles on the lung. 3. The external intercostals in the dorsal third of the rostral interspaces were found to have a large inspiratory effect. However, this effect decreases rapidly both toward the costochondral junctions and toward the base of the rib cage. As a result, it is reversed to an expiratory effect in the most caudal interspaces. The internal intercostals in the caudal interspaces have a large expiratory effect, but this effect decreases ventrally and rostrally, such that it is reversed to an inspiratory effect in the most rostral interspaces. 4. These observations indicate that the canine external and internal intercostal muscles do not have distinct inspiratory and expiratory actions as conventionally thought. Therefore, their effects on the lung during breathing will be determined by the topographic distribution of neural drive.  (+info)

Spatial distribution of external and internal intercostal activity in dogs. (4/190)

1. The observation that the external and internal interosseous intercostal muscles in the dog show marked regional differences in mechanical advantage has prompted us to re-examine the topographic distribution of electrical activity among these muscles during spontaneous breathing. 2. Inspiratory activity was recorded only from the areas of the external intercostals with an inspiratory mechanical advantage, and expiratory activity was recorded only from the areas of the internal intercostals with an expiratory mechanical advantage. The expiratory discharges previously recorded from the caudal external intercostals and the inspiratory discharges recorded from the rostral internal intercostals were probably due to cross-contamination. 3. Activity in each muscle area was also quantified relative to the activity measured during tetanic, supramaximal nerve stimulation (maximal activity). External intercostal inspiratory activity was consistently greater in the areas with a greater inspiratory advantage (i.e. the dorsal aspect of the rostral segments) than in the areas with a smaller inspiratory advantage, and internal intercostal expiratory activity was invariably greatest in the areas with the greatest expiratory advantage (i.e. the dorsal aspect of the caudal segments). 4. This topographic distribution of neural drive confers to the external intercostal muscles an inspiratory action on the lung during breathing and to the internal interosseous intercostals an expiratory action.  (+info)

The temperature sensitivity of miniature endplate currents is mostly governed by channel gating: evidence from optimized recordings and Monte Carlo simulations. (5/190)

The temperature dependence of miniature endplate current (MEPC) amplitude (A(c)), 20-80% rise time (t(r)), and 90-33% fall-time (t(f)) was determined for lizard (Anolis carolinensis) intercostal muscle using broadband extracellular (EC) and voltage clamp (VC) recordings. Voltage clamp methods were optimized for the fast MEPC rising phase using custom electronics. From 0-43 degrees C, A(c) increased by approximately 4.2-fold, while t(r) and t(f) decreased by approximately 3.6- and approximately 9.5-fold, respectively. Arrhenius plots were smoothly curved, with small apparent Q(10) (A(c)) or (Q(10))(-1) (t(r) and t(f)) values mostly well below 2.0. Nearly identical extracellular and voltage clamp results ruled out measurement artifacts, even for the shortest t(r) values (<60 microseconds). Monte Carlo simulation of MEPCs showed that a single underlying rate cannot determine the observed temperature dependence. To quantitatively reproduce the experimental t(f) results, a minimal model required activation energies of 46.0 (Q(10) approximately 2.0) and 63.6 (Q(10) approximately 2.5) kJ mol(-1) for channel opening and closing, respectively, and accounted for most of the observed changes in A(c) and t(r) as well. Thus, relatively large but offsetting temperature sensitivities of channel gating mostly govern and minimize the temperature dependence of MEPCs, preserving the safety factor for neuromuscular transmission. Additional temperature-sensitive parameters that could fine-tune the minimal model are discussed.  (+info)

Muscle kinematics for minimal work of breathing. (6/190)

A mathematical model was analyzed to obtain a quantitative and testable representation of the long-standing hypothesis that the respiratory muscles drive the chest wall along the trajectory for which the work of breathing is minimal. The respiratory system was modeled as a linear elastic system that can be expanded either by pressure applied at the airway opening (passive inflation) or by active forces in respiratory muscles (active inflation). The work of active expansion was calculated, and the distribution of muscle forces that produces a given lung expansion with minimal work was computed. The calculated expression for muscle force is complicated, but the corresponding kinematics of muscle shortening is simple: active inspiratory muscles shorten more during active inflation than during passive inflation, and the ratio of active to passive shortening is the same for all active muscles. In addition, the ratio of the minimal work done by respiratory muscles during active inflation to work required for passive inflation is the same as the ratio of active to passive muscle shortening. The minimal-work hypothesis was tested by measurement of the passive and active shortening of the internal intercostal muscles in the parasternal region of two interspaces in five supine anesthetized dogs. Fractional changes in muscle length were measured by sonomicrometry during passive inflation, during quiet breathing, and during forceful inspiratory efforts against a closed airway. Active muscle shortening during quiet breathing was, on average, 70% greater than passive shortening, but it was only weakly correlated with passive shortening. Active shortening inferred from the data for more forceful inspiratory efforts was approximately 40% greater than passive shortening and was highly correlated with passive shortening. These data support the hypothesis that, during forceful inspiratory efforts, muscle activation is coordinated so as to expand the chest wall with minimal work.  (+info)

Characterization of the early development of specific hypaxial muscles from the ventrolateral myotome. (7/190)

We have previously found that the myotome is formed by a first wave of pioneer cells generated along the medial epithelial somite and a second wave emanating from the dorsomedial lip (DML), rostral and caudal edges of the dermomyotome (Kahane, N., Cinnamon, Y. and Kalcheim, C. (1998a) Mech. Dev. 74, 59-73; Kahane, N., Cinnamon, Y. and Kalcheim, C. (1998b) Development 125, 4259-4271). In this study, we have addressed the development and precise fate of the ventrolateral lip (VLL) in non-limb regions of the axis. To this end, fluorescent vital dyes were iontophoretically injected in the center of the VLL and the translocation of labeled cells was followed by confocal microscopy. VLL-derived cells colonized the ventrolateral portion of the myotome. This occurred following an early longitudinal cell translocation along the medial boundary until reaching the rostral or caudal dermomyotome lips from which fibers emerged into the myotome. Thus, the behavior of VLL cells parallels that of their DML counterparts which colonize the opposite, dorsomedial portion of the myotome. To precisely understand the way the myotome expands, we addressed the early generation of hypaxial intercostal muscles. We found that intercostal muscles were formed by VLL-derived fibers that intermingled with fibers emerging from the ventrolateral aspect of both rostral and caudal edges of the dermomyotome. Notably, hypaxial intercostal muscles also contained pioneer myofibers (first wave) showing for the first time that lateral myotome-derived muscles contain a fundamental component of fibers generated in the medial domain of the somite. In addition, we show that during myotome growth and evolution into muscle, second-wave myofibers progressively intercalate between the pioneer fibers, suggesting a constant mode of myotomal expansion in its dorsomedial to ventrolateral extent. This further suggests that specific hypaxial muscles develop following a consistent ventral expansion of a 'compound myotome' into the somatopleure.  (+info)

Postinspiratory activity of the parasternal and external intercostal muscles in awake canines. (8/190)

Previous studies have shown in awake dogs that activity in the crural diaphragm, but not in the costal diaphragm, usually persists after the end of inspiratory airflow. It has been suggested that this difference in postinspiratory activity results from greater muscle spindle content in the crural diaphragm. To evaluate the relationship between muscle spindles and postinspiratory activity, we have studied the pattern of activation of the parasternal and external intercostal muscles in the second to fourth interspaces in eight chronically implanted animals. Recordings were made on 2 or 3 successive days with the animals breathing quietly in the lateral decubitus position. The two muscles discharged in phase with inspiration, but parasternal intercostal activity usually terminated with the cessation of inspiratory flow, whereas external intercostal activity persisted for 24.7 +/- 12.3% of inspiratory time (P < 0.05). Forelimb elevation in six animals did not affect postinspiratory activity in the parasternal but prolonged postinspiratory activity in the external intercostal to 45.4 +/- 16.3% of inspiratory time (P < 0.05); in two animals, activity was still present at the onset of the next inspiratory burst. These observations support the concept that muscle spindles are an important determinant of postinspiratory activity. The absence of such activity in the parasternal intercostals and costal diaphragm also suggests that the mechanical impact of postinspiratory activity on the respiratory system is smaller than conventionally thought.  (+info)

Lateral to the costal angle, there are 3 layers of muscles? external intercostal muscle (EICM), the internal intercostal muscle (IICM) and the innermost intercostal muscle (IMICM) (Figure 3). The innermost intercostal muscle, also called the intercostalis intimus muscle, is a flimsy innermost muscle layer which readily permits local anesthetic diffusion. Deep to the innermost intercostal muscle is the parietal pleura. From the costal angle onwards, the main ICNs and vessels, grouped as a neurovascular bundle, are arranged in the vein, artery and nerve (VAN) orientation from superior to inferior. Note that this constant arrangement does not apply for the collateral bundle. Both neurovascular bundles are found between the internal intercostal muscle and innermost intercostal muscle but the main bundle is found within the costal groove or near the inferior margin of the upper rib of an ICS while the collateral bundle is found at the superior border of the lower rib ...

Results: Eighty patients (54 males and 26 females; mean age, 68 ± 14 years) were enrolled. Diaphragm muscle thickness decreased, increased, and remained unchanged in 50 (63%), 15 (19%), and 15 (19%) patients, respectively. Intercostal muscle thickness decreased, increased, and remained unchanged in 48 (60%), 15 (19%), and 17 (21%) patients, respectively. Decreased diaphragm or intercostal muscle thickness was associated with prolonged mechanical ventilation (median difference (MD), 3 days; 95% CI (confidence interval), 1-7 and MD, 3 days; 95% CI, 1-7, respectively) and length of ICU stay (MD, 3 days; 95% CI, 1-7 and MD, 3 days; 95% CI, 1-7, respectively) compared with the unchanged group.

Rationale:. Electrical stimulation of the dorsal columns of the spinal cord (Spinal Cord Stimulation or SCS) for pain relief has been used in humans for several decades. The most common indication for SCS is the treatment of refractory neuropathic leg pain, particularly when these symptoms persist after an anatomically successful operation (Failed Back Surgery Syndrome or FBSS).. Low frequency - conventional - SCS (LF-SCS) is applied in frequencies ranging from 30 to 60 Hertz (Hz) and the subject feels paraesthesias in the painful area, which is considered the ideal situation. Recently, LF-SCS has been challenged by the development of stimulation modes at higher frequencies which provide pain relief at sub-perception threshold, i.e. without paraesthesias. A recent case series reported that High Frequency Spinal Cord Stimulation (HF-SCS) appears to show better pain relief for both back and limb pain in comparison to LF-SCS, and also to be effective in some subjects who did not respond to ...
This study aims to investigate noninvasive indices of neuromechanical coupling (NMC) and mechanical efficiency (MEff) of parasternal intercostal muscles. Gold standard assessment of diaphragm NMC requires using invasive techniques, limiting the utility of this procedure. Noninvasive NMC indices of parasternal intercostal muscles can be calculated using surface mechanomyography (sMMGpara) and electromyography (sEMGpara). However, the use of sMMGpara as an inspiratory muscle mechanical output measure, and the relationships between sMMGpara, sEMGpara, and simultaneous invasive and noninvasive pressure measurements have not previously been evaluated. sEMGpara, sMMGpara, and both invasive and noninvasive measurements of pressures were recorded in twelve healthy subjects during an inspiratory loading protocol. The ratios of sMMGpara to sEMGpara, which provided muscle-specific noninvasive NMC indices of parasternal intercostal muscles, showed nonsignificant changes with increasing load, since the ...
A fibrous band or inscription frequently interrupts the internal oblique and the intercostal muscles. In rare instances a similar inscription has been seen opposite the twelfth or even the eight rib. They apparently represent tendinous intersections between the internal oblique and the internal intercostal muscles. An additional slip occasionally arises from the eight costal cartilage. It has been reported that the internal oblique inserts onto the eleventh rib in 1% of cases, the tenth in 66.5%, the ninth in 31%, and the eighth rib in 1.5% of cases. Mori reported that in 200 Japanese males, the highest rib of insertion was the eleventh , on the right side, in 34% and on the left in 36% and the tenth, on the right side in 56% and on the left in 64%.

Intercostal muscles are muscle groups that are situated in between the ribs that create and move the chest wall. The muscles are broken down into three layers, and are primarily used to assist with the breathing process.
The image above is seen from the inside. The yellowish bones are the sternum in the centre and the ribs and clavicle (at the very top). Between the ribs can be seen the internal intercostals. In the front of the ribcase, looking from the bottom of each muscle (i.e., the top of each rib), the muscles go diagonally INWARD. At the bottom of the sternum can be seen the tranversus thoracis muscle which originates there and inserts onto the inner surfaces of the second to the sixth costal cartilages. You can really feel these muscles when you cough, as you press your sternum in hard. At the bottom of the images can be seen the edge of the diaphragm. The external intercostals (not shown), take the opposite path, that is they go downward and OUTWARD when viewed from the back. It is important to understand that having the muscles on diagonals increases the amount of work they can do - a longer muscle can become shorter on contraction than can a shorter, vertical muscle, as it contracts along the full ...
The fine structure of the mouse and human intercostal muscle neuromuscular junction was studied after brief fixation in a new formol-sucrose fixative. This primary formalin fixation was followed by brief postosmication in buffered 1 per cent osmium tetroxide. Muscle blocks were embedded in methacrylate or Epon 812 epoxy resin. Marked similarities between mouse and human motor end-plates were observed. Neuromuscular junctions from both mouse and human intercostal muscle showed synaptic vesicles, primary and secondary synaptic clefts, and layered differentiation of the amorphous surface material (ASM) present on the surface of the Schwann cell plasma membrane and on the muscle surface membrane in the region of the neuromuscular junction. An attempt to stain the ASM with lead was unsuccessful. Observations on thick and thin plastic-embedded sections stained by PAS after diastase digestion showed that the ASM within the subneural apparatus is PAS positive.

Back pain that occurs alongside shortness of breath can be a cause for concern, especially if youre not so sure about the cause. Here are some possible reasons why back pain and shortness of breath may occur together:. Intercostal muscle strain. An intercostal muscle strain refers to a muscle injury that occurs in between two or more ribs. The intercostal muscles help connect the ribs and make up most of the chest wall. When one or more of these muscles become strained or overstretched, you might feel a tenderness along the back. In severe cases, youre likely to experience intense back pain coupled with shortness of breath since the muscles affected are attached to the rib cage, which expands and contracts as you breathe.. Severe kyphosis. When viewed from the side, the spine is normally not a straight line. The rib cage is designed to have a normal forward curvature known as kyphosis, which curves at an angle of 20 to 50 degrees depending on a persons height and spine structure. When this ...

Hiccups are a spasm of the diaphragm. Intercostals also aid respiration Inter- (between) Costals (ribs). Internal intercostals lift the ribs during respiration, whilst external intercostals draw the ribs together during expiration to lessen the volume of the rib cage and thoracic cavity to push air out of the lungs. Biceps and triceps are antagonist (have the opposite functions). Triceps (with three heads) extend the forearm so it can be held straight, while biceps (two heads) flex the forearm and draw it up. Tendons connect muscles to the bone, these are formed from the connective tissue that cover the muscle. They are dense white cords of tissue which are strong and flexible, they serve to anchor muscles to the bone. Types of muscles and movement ...

The diaphragm only descends about 1cm then it comes to rest on the contents of the abdomen like the stomach, spleen and liver. At this point it doesnt descend any further but instead acts upwards on the ribs, pulling them upwards and outwards, further increasing the volume of the chest.. 2. External intercostals contract lifting and widening ribs. The external intercostals are located between the ribs and they pull the top 6 ribs outwards and upwards, while the lower six are just pulled outwards.. 3. These two motions increase the thoracic cavity space.. 4. This expansion of space reduces pressure in the pleural cavity (a sac that surrounds the lungs) which allows the lungs to expand.. 5. As the lungs expand, there is a reduction of pressure in the pulmonary cavity relative to the atmosphere and air is drawn in towards the alveoli.. Breathing Out. 1. The diaphragm relaxes and the buildup of pressure in the abdominal cavity pushes back up on the diaphragm which then reduces the thoracic cavity ...

The lungs are located inside the rib cage. They are made of spongy, elastic tissue that stretches and constricts as we breathe. The trachea and the bronchi are the airways that bring air into the lungs; they are made of smooth muscle and cartilage, which allows the airways to constrict and expand. The lungs and airways bring in oxygen-enriched air and get rid of waste carbon dioxide made by the cells. When we inhale, the diaphragm and the intercostal muscles (muscles between the ribs) contract and expand the chest cavity, which allows air to flow in through the airways and inflate the lungs. When we exhale, the diaphragm and intercostal muscles relax and the chest cavity gets smaller, which forces air to flow from the lungs and out of the airways to the outside air. Their principal function is to transport oxygen from the atmosphere into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere. This exchange of gases is accomplished in the mosaic of specialized ...

To search for use-dependent sodium channel blockers to selectively solve skeletal muscle hyperexcitability in hereditary myotonias, mexiletine (MEX; compound I) and its newly synthetized analogs, 2-(4-chloro-2-methylphenoxy)-benzenethanamine (compoundII) and (−)-S-3-(2,6-dimethylphenoxy)-2-methylpropanamine (compoundIII), were tested on intercostal muscle fibers from the myotonic ADR mouse through use of the standard current-clamp microelectrode technique. In parallel, the effects of these compounds on the sodium channels were measured on frog muscle fibers under voltage-clamp conditions. The tonic and use-dependent blocks of peak sodium currents (INamax) produced by each compound were evaluated by using a single depolarizing pulse and a pulse train at 10 Hz frequency, respectively. At 10 and 50 μM, MEX decreased the occurrence of spontaneous excitability in myotonic muscle fibers; 100 μM was required to decrease the amplitude of the action potential and the stimulus-induced firing of the ...
and its the way your body regulates the disruption of homeostasis - or stress. With proper breathing, you have the ability to consciously override your bodys reaction to stress and redirect it toward the desired outcome. There are many muscles that assist with breathing, however, the primary muscles that help you breathe are the diaphragm and the intercostals. The diaphragm attaches to the bottom of the ribs and moves the ribcage down and out when you inhale. The intercostal muscles run between the ribs and help expand and contract your ribs. ...
A robotic surgical tool includes an end effector having a pair of fingers and incorporating a mechanical advantage. In specific embodiments, a pulley and cable mechanism is used to actuate the end effector by applying cable tension. The coupling between the pulleys and the fingers of the end effector takes advantage of changes in moment arms for force transfer to avoid or minimize force reduction between the applied cable tension and the resultant force at or near the distal tip of each finger. In some embodiments, the coupling of the pulleys and fingers results in a force gain, a moment gain, or both.

A parasternal heave is a precordial impulse that may be felt (palpated) in patients with cardiac or respiratory disease. Precordial impulses are visible or palpable pulsations of the chest wall, which originate on the heart or the great vessels. A parasternal impulse may be felt when the heel of the hand is rested just to the left of the sternum with the fingers lifted slightly off the chest. Normally no impulse or a slight inward impulse is felt. The heel of the hand is lifted off the chest wall with each systole. Palpation with the fingers over the pulmonary area may reveal the palpable tap of pulmonary valve closure (palpable P2) in cases of pulmonary hypertension. Parasternal heave occurs in the setting of right ventricular enlargement (hypertrophy) or very rarely severe left atrial enlargement. This is due to the position of the heart within the chest: the right ventricle is most anterior (closest to the chest wall). Hypertrophy of the right side of the heart will occur when the right side ...

The muscles of the thoracic cage develop from the ventral portions of the thoracic somites of the embryo. Like the neck and abdomen they clearly demonstrate the muscle pattern of the vertebrate body wall. Unlike the neck and abdomen, however, the thoracic body wall has well-developed ribs that dominate the wall and limit the movements of the vertebral column. Because of the well-developed segmental ribs, the muscles of the thoracic wall retain their segmental origins. Primitively, these intercostal muscles were the major muscles of locomotion in vertebrate animals. They generated the lateral undulating movements of the vertebral column that early vertebrates used to propel themselves forward. In the human body these muscles have a variety of functions. They help to stiffen the thoracic cage and they help to produce the rib movements that increase and decrease the thoracic volume, activities, both of which, help increase respiratory efficiency. The uniquely mammalian diaphragm muscle is a complex ...
Fatalities caused by car accidents accounted for 1.2 million worldwide in 2004. Chest injuries are the second death cause, after head injuries, in vehicle accidents. Devices to predict risk of injury are fundamental to develop and evaluate restraint systems that can mitigate the injury severity and reduce the fatalities. This can be achieved with mathematical Human Body Models (HBM). An HBM needs to be biofidelic, both in terms of size and biomechanical response. Herein, the biofidelity of the thorax region in an HBM is evaluated. The evaluation focuses on whole body kinematics and chest response during frontal car accidents. Finite element simulations with an HBM were performed with the code LS-DYNA [1]. A modified version of Total HUman Model for Safety v3.0 (THUMS) [2] has been the basis for the work presented here. THUMS was modified to improve its robustness and numerical stability. The meshes of the rib cage, skin around the ribcage, and intercostal muscles were refined. THUMS
In this type of inhalation the center of the diaphragm is slowly moving downwards and hence opposed by the gradually growing resistance of the internal organs, pushed back up by the abdominal muscles as well as by the lower-back and torso muscles. As a result the downward motion of the center of diaphragm is stopped and the edges of gradually flattening diaphragm will rise up. These edges are attached to the ribs, causing them to move up. The upper back is pushed backwards causing us to stand more erect. When the inhalation is done slowly and gently the participation of the intercostal muscles, running between the ribs and lifting them up, will be minimal- resulting in the most cost effective inhalation. ...
In order to maintain a constant body mass, energy input must equal energy output. If we eat too much, without doing any exercise we will gain weight and may become over weigh. If we eat too little we will lose weight.. Oxygen for aerobic respiration is obtained from the atmosphere when we take air into our lungs to breathe. Carbon dioxide produced as a waste product of aerobic respiration, passes out of our bodies as we breathe out.. The lungs are a mammals organs of gaseous exchange. Air enters through the nose or mouth and passes down the larynx and then the trachea. The trachea divides into two bronchi (singular, bronchus) one to each lung. Each bronchus divides further into smaller tubes called bronchioles ending in tiny air sacs called alveoli.. To breathe in - Intercostal muscles contract and raise the ribcage. (raises up and out). The diaphragm contracts and flattens the floor of the chest cavity. Both these contractions increase the volume and decrease the pressure of the chest cavity ...
It involves inspiration and expiration: 1. Inspiration: It is a process by which fresh air enters the lungs. The diaphragm, intercostal muscles and abdominal muscles play an important role. (i)
Phillies left fielder Jay Bruce has a sprained right intercostal muscle, which means he pulled a muscle in his rib cage. The team placed him on the 10-day injured list Wednesday, but he is optimistic he will not miss much more time than that.
You might not study anatomy to determine what is exactly taking place, but you learn to really feel what is going on so you can play your edges. Imagine if you did not practice yoga....all the muscles in the body that would rarely get used to their potential. Take the latissiumus dorsi for example. This superficial muscle covers 2/3s of the back and the top of it is attached to the inside of the humerus bone (the top bone of the arm). When you actively reach up those arms in Warrior I, you are lengthening the latissimus dorsi because the arms lift it up. In the front of the body, youre expanding the intercostal muscles that are between each rib. The shoulder muscles get contracted and stronger. The quadriceps are actively holding the foundation as the feet stay planted. There are layers of muscles over the few I have mentioned; therefore, know there is more happening that meets the eye ...
Finally went to GP who listened to chest, said it sounded clear, and diagnosed a pulled intercostal muscle and prescribed a gel rub. Next day pain was worse and I brought up some blood (no cough it just surfaced!) So straight back to docs, a different one who promptly took some blood and sent me straight to X-ray. Went home and later on in the day had a phone call from surgery to say I must go straight back to the hospital and be prepared to be admitted......with a suspected blood clot on my lung. After a lengthy wait and more blood tests was given a clot busting injection in my abdomen. Kept on monitor through the night and later next day had a CT scan after having dye injected to highlight if any clot was in evidence. All seemed very surreal and total lack of sleep due to noise left me exhausted and to cap it all I had a nasty panic attack whilst there! Still not sure about it all but see doc on Friday if hospital report is back ...

Well, you cant really fill your belly with air, although this is often said, mostly as a coaching cue. Singing teachers say the same thing for slightly different reasons. The problem is that if you think about your chest while inhaling, you tend to just use your intercostal muscles to expand the chest cavity, while allowing the abdominal organs to push the diaphragm up, or an least keep it from going down much. Try doing that while holding a hand on your abdomen. It actually goes in. If the abdomen wall is going in, the abdominal contents are going somewhere, and that is upwards ...
Nothing fishy. The first anatomical area to be lacerated and avulsed was the esophagus and trachea. From the contraction of the diaphragm, intercostal muscles and the fluctuation of the esophageal sphincter and trachea from pain, air (scream) etc would be rapidly force from the lacerated ends of these to pieces of anatomy causing what would sound like a goat whinny ...

One cheery bit of the experience for the prurient minded (Aine you can come out now) Aud, my SO, (bless her little cotton socks) brought me in a Walkman with built in FM radio and headphones, so I could listen to Classic FM when I couldnt sleep. She also brought in small selection of tapes for when the radio was playing something I dont like. I couldnt move more than 5 feet from my bed as I was attached to an intravenous Insulin pump, therefore all sanitary arrangements come to you especially significant is the urine bottle, I cannot use these lying down but have to sit on the side of the bed (all will be revealed in a moment).

Objective: There are many risk factors for postoperative bronchopleural fistula (BPF), including extensive resection, diabetes, chronic infection, perioperative steroid therapy, preoperative chemotherapy, and radiotherapy, the risk of bronchopleural fistula increases with resection for inflammatory diseases, especially Mycobacterium tuberculosis (MTB). The aim of this study is to evaluate the efficacy and safety of using double pedicled intercostal muscle flaps with dual blood supply to buttress the bronchial stump after pneumonectomy for tuberculous lesions as a prophylactic new technique from post-pneumonectomy BPF. Methods: Between 2007 and 2011, 47 patients with pneumonectomy for post tuberculous lesions in the department of cardiothoracic surgery, Zagazig University Hospital were divided into two groups. Group A: 28 patients with single pedicled intercostal muscle flap used and applied on the bronchial stump after pneumonectomy. Group B: 19 patients with double pedicled intercostal muscle flaps
The intercostal muscles run between each rib. When a person needs to breathe in, these muscles contract and pull the ribs upward. This creates more room inside the chest for the lungs to fill.[3] When a person is resting, the about 30% to 40% of their ability to breathe comes from the intercostal muscles.[6] The intercostal muscles are controlled by the intercostal nerves. The medulla tells the intercostals when to contract by sending messages through these nerves. The intercostal nerves are not as well protected as the phrenic nerves. The intercostal nerves run along the thoracic spine (which is in the upper to middle back) and connect to the intercostal muscles. This means that if a person injured their thoracic spine, they might not be able to use their intercostal muscles. They would then lose 30% to 40% of their ability to breathe. However, since the nerves that control the diaphragm are much farther up in the spine and better protected, the person would still be able to use their diaphragm ...
The functional outcomes of respiratory muscle loading by chemical (e.g. hypercapnia), mechanical (i.e. external mechanical loading) or ventilatory (e.g. exercise) factors can be either positive, such as through an increase in pressure-generating capacity of the inspiratory muscles or detrimental, such as by fatigue. Neurophysiological responses to respiratory muscle loading can occur at one or more points along the pathway from motor cortex to muscle. This paper describes the respiratory pump and upper airway motoneuron responses to the imposition of acute loads including processes of pre-activation, respiratory reflexes, potentiation and fatigue. It also considers changes suggestive of adaptation to chronic loading either from specific respiratory muscle training programs or as part of disease processes such as chronic obstructive pulmonary disease or obstructive sleep apnoea.. ...
Introduction Dynamic hyperinflation (DH) is characterised by an increase in end-expiratory lung volume (EELV) and contributes to exercise limitation in Chronic Obstructive Pulmonary Disease (COPD) patients. Neural respiratory drive (NRD) directly reflects the load-capacity relationship of the respiratory system and is therefore expected to increase with DH. However, there are limited data investigating the effects of isolated increases in EELV on NRD. We hypothesised that 1) increases in EELV induced by continuous positive airway pressure (CPAP) would increase NRD in healthy subjects and 2) with the change in lung volume, NRD to the parasternal intercostal muscles would increase to a greater extent than that to the diaphragm at higher levels of CPAP. ...
In NF dysplasia causes severe wedging, strong rotation and scalloping of the vertebral bodies that result in a progressive abnormal spinal curvature [11]. Spindling of transverse processes, foraminal enlargement, saccular dilatations and pencilling of vertebral margins and apical ribs may contribute to costovertebral subluxation or dislocation of the rib head towards the neural foramen. A dumbbell intraspinal neurofibroma or dural ectasia may coexist. Spinal cord compression may be caused by vertebral angulation or tumorous lesions around the spinal canal [12, 13].. The painful rib hump is an important clinical sign that is introduced for the first time by this report. A careful search for this sign is recommended. There is a high index of suspicion of an intraspinal rib displacement at the apex of a progressive short, sharp, angular, kyphoscoliotic curve when a region sensitive to pressure is clinically detected.. Pain is attributed to the mobile rib head and it should be considered as a ...
The fine structure of the developing neuromuscular junction of rat intercostal muscle has been studied from 16 days in utero to 10 days postpartum. At 16 days, neuromuscular relations consist of close membrane apposition between clusters of axons and groups of myotubes. Focal electron-opaque membrane specializations more intimately connect axon and myotube membranes to each other. What relation these focal contacts bear to future motor endplates is undetermined. The presence of a group of axons lying within a depression in a myotube wall and local thickening of myotube membranes with some overlying basal lamina indicates primitive motor endplate differentiation. At 18 days, large myotubes surrounded by new generations of small muscle cells occur in groups. Clusters of terminal axon sprouts mutually innervate large myotubes and adjacent small muscle cells within the groups. Nerve is separated from muscle plasma membranes by synaptic gaps partially filled by basal lamina. The plasma membranes of ...
The distribution and development of Met-enkephalin-Arg6-Gly7-Leu8 (Enk-8)-containing neurons in the sensory ganglia of the rat were investigated by means of immunocytochemistry using specific antiserum to this octapeptide. Enk-8-like immunoreactivity first appeared in neurons of the trigeminal ganglia of the 18-day embryo, then in the dorsal root ganglia of the 21-day embryo, thus exhibiting a rostrocaudal gradient in terms of appearance and abundance. The number of immunoreactive neurons in these sensory ganglia peaked on the 5th-7th postnatal days, with several small ones observed in each section (1.0-1.4% of total cell number). About 30-40% of these Enk-8-like immunoreactive neurons were also immunoreactive to substance P. Subsequently, Enk-8-like immunoreactivity in the sensory ganglia was decreased and was rarely detected in adult animals. However, colchicine treatment revealed the presence of several Enk-8-containing neurons per section prepared from mature rat. All these neurons were small (12.5
The breathing centers are grey nuclei made up of nerve cell bodies that are found in the medulla oblongata. These nuclei are parts of the reticular formation of the brainstem (medulla, pons, midbrain). Through the phrenic nerve and the thoracic branches of the intercostal nerves, these breathing centers of the central nervous system control the movements of the diaphragm and intercostal muscles that make inhalation and exhalation (expiration) possible in breathing. The destruction of these grey nuclei in the medulla causes respiration arrest and death. ...
During inspiration, the contraction of intercostall muscle causes the O2 rich air to go into lungs that makes ribcage moves toward and chest bone moves downward. Most of the free air will be transferred into air sacks as air reserve. During expiration, intercostal muscle relaxes and ribcage and chest bones go to back to the first position so that the chest cavity becomes narrow and the air pressure inside becomes higher that outside. Consequently, the CO2 rich air comes out from lungs. At the time, the chest cavity becomes narrow; the air from air sacks goes into lungs and O2 is relased from capillary vessel in lungs ...
To fully utilize our design for breathing the abdominal muscles needs to be fully relaxed to allow the diaphragm to expand down into the abdomen on the inhalation.. The contraction of the diaphragm draws air down into the lungs. On the exhalation, the diaphragm is aided by the contraction of powerful abdominal muscles. The abdominal and intercostal muscles between the ribs are considered the primary muscles associated with breathing.. Our breathing system is designed to draw breath down into the lower lungs. The lower lungs have about five times the capacity of the smaller upper lobes of the lung. In addition blood circulation to the top of the lungs is less than 0.1 litre per minute, well below the circulation to the mid and lower lungs. The flow of blood to the middle of the lungs is about 0.6 litres per minute and at the bottom of the lungs this increases to over 1 litre per minute.. The purpose of breathing is to draw in air and allow for an exchange of oxygen and carbon dioxide in the ...
Why are respiratory infections so common in spinal cord injury (SCI) patients? Weve mentioned the prevalence before, but want to share some data we recently found.. According to the University of Washingtons School of Medicine, respiratory infections such as pneumonia, are the leading cause of death in SCI patients. Compare this to heart disease, cancer and stroke which are the main causes of death in the general population.. SCI affect the respiratory system the muscles that are needed to pull air in and push it out of the lungs are often affected by a spine injury. Without the intercostal muscles working properly, the patient is unable to effectively cough up mucus which leads to an excess in the lungs that makes it harder to breath.. There are ways to make sure the lungs are kept clear such as with the use of suction or quad coughing, a process that involves a caregiver pushing down on the chest to force the air and mucus out. In addition, receiving a pneumonia vaccine called Penumovax ...
The Kansas City Royals placed all-star catcher Salvador Perez on the 10-day disabled list on Sunday due to a strained intercostal muscle on the right side of his chest, per reports.. Perez, 27, left Fridays game against the Seattle Mariners after 6 innings of play and an MRI revealed his injury. The DL move was made retroactive to August 5th.. Perez has been durable and his last sting on the disabled list was back in 2012 when he landed on the 60-day DL with a knee injury.. Perez is batting .278 with 21 home runs and 65 RBIs this season for Kansas City who are battling the Cleveland Indians for the top spot in the AL Central and also fending off the Tampa Bay Rays for the second AL Wild Card Spot.. In a corresponding move, Cam Gallagher was recalled from Triple-A Omaha to fill the empty roster spot created by Perezs injury.. ...

My 30th TTM success came yesterday (the same day I got Mike McCormick) in the form of the above baseball. Orioles #1 draft pick (4th overall) from the 2008 draft, Brian Matusz. I mailed to Matusz on February 10, 2011 and got him back yesterday (September 2, 2011), making him an almost 7-month TAT. Yikes. I sent to him during spring training in hopes of a quick return, but had to wait pretty much all season. Matusz has had a forgettable 2011 campaign. He is currently 1-7 with a 9.07 ERA. Pretty darn terrible. It appears that he didnt take the past offseason as seriously as one would hope and came into spring training out of shape. He missed a week in spring training after having a wart removed from a finger on his throwing hand and then missed about a month thereafter when he strained his intercostal muscle.

To close the gaps (6) which result between the end or edge sections (7) of the gravure printing plates (2) when the latter are clamped on form cylinders (1) of rotary gravure presses, the gap (6) is covered with a cover element (8) in which at least that surface region which lies on the end or edge sections (7) of the gravure printing plate (2) and covers the gap (6) is deformable under pressure and can therefore be matched up with the surface contour in the gap region, the cover element is pressed onto the surface of the gravure printing plate, the resulting gap cavity is filled with a curable filling compound and, when curing of the filling compound is complete, the cover element is removed. It is particularly advantageous to use cover elements which are in the form of hollow bodies and which are filled with a pressure-generating and pressure-transmitting medium, and the pressure exerted on the deformable surface of the cover element which lies on the gravure printing plate, and hence also the surface
EchoCG is performed from the following standard sensor positions: 1. Parasternal access - region 3 - 4 intercostal spaces to the left of the sternum. 2. Apical (apical) - apical impulse zone. 3. Subkostal - from the xiphoid process. 4. Suprasternal - jugular fossa. In some standard positions of the sensor, ultrasound examination of the heart is carried out in several directions: along the long and short axis of the organ (as a rule, it is parasternal and subkostal). Since B mode gives the most complete picture of the structural and geometric features of the organ under study, the study usually begins with it. Below are the schematic images of the heart and its structures in B - mode in the study of the main approaches.. Systole (valves open), diastole (valves closed).. Parasternal access on the short axis at the level of the aortic valves.. Research in the M -mode is often carried out from the left parasternal access along the long axis of the heart. The angle of inclination of the sensor is ...

Question - Having shooting pain in lower ribs. Achy and painful to touch. Ultrasound normal. Worrisome, Ask an Orthopaedic Surgeon
The idea that a machine can be decomposed into simple movable elements led Archimedes to define the lever, pulley and screw as simple machines. By the time of the Renaissance this list increased to include the wheel and axle, wedge and inclined plane. The modern approach to characterizing machines focusses on the components that allow movement, known as joints. Wedge (hand axe): Perhaps the first example of a device designed to manage power is the hand axe, also see biface and Olorgesailie. A hand axe is made by chipping stone, generally flint, to form a bifacial edge, or wedge. A wedge is a simple machine that transforms lateral force and movement of the tool into a transverse splitting force and movement of the workpiece. The available power is limited by the effort of the person using the tool, but because power is the product of force and movement, the wedge amplifies the force by reducing the movement. This amplification, or mechanical advantage is the ratio of the input speed to output ...
There is a strong territory ownership advantage in U. mjoebergi. Owners won 92% of fights when floaters attempted to usurp their territory. Estimating effect sizes allows us to directly compare the importance of the four factors we examined. A mechanical advantage due to access to a burrow while fighting had the strongest influence on the proportion of fights the owner won (r=0.47; 95% CI: 0.18-0.69). The period of active residency on the territory also appeared to have an effect (r=0.26; 95% CI: −0.09 to 0.56), albeit a marginally non-significant one. Information about greater food availability had only a small effect (r=0.18; 95% CI: −0.10 to 0.43), and there was no evidence that a difference in the intrinsic fighting ability of floaters and owners contributes to the ownership advantage (r=0.02; 95% CI: −0.20 to 0.23).. It is initially surprising that floaters were not detectably weaker than owners, because at least some floaters are males that have recently lost their own territory. One ...
