Semitendinosus muscle

which then leads to the jump and follow through. The jump follow through occurs when the pole vaulter lances themselves straight up in order to clear the bar. During the entire event the pole vaulters body is enticed in play by play action where every muscle takes…

femur. These two joints work together to form a hinge joint allowing the knee to bend and straighten and to also rotate slightly from side to side. Muscles There are two main muscles groups of the knee, the hamstrings, quadriceps and muscles of the calf all work to flex, extend and keep the knee stable and well aligned. The quadriceps is made of 4 muscles including the vastus medialis, vastus intermedius, vastus lateralis and rectus femoris located on the front of the thigh and is responsible…

Dogs to Humans Humans and dogs are similar in many different ways, one way is that they have similar muscular systems. We humans have some similar muscles as dogs like, gluteal muscle, biceps, latissimus dorsi, trapezius, deltoid, and the external oblique. The different muscles are used by dogs and humans in pretty much the same sense so they can run, walk, and jump. The dog’s muscular system is one of the biggest systems in their body. There are two important functions of the muscular system…

2007). There is an innumerable amount of physiological benefits of exercise such as to combat health conditions and diseases. Regular physical activity can improve muscle strength and boost endurance during day life tasks. Exercise can also help to prevent weight gain, promote the loss of weight and supports in other to gain muscle fitness among a wide variety of other benefits. A lot of research have been done of these physiological benefits of exercise, nevertheless physical…

and your body starts digging into it 's own reserves to survive, body starts to eat itself and chooses easy to process muscle fibers first, fat…

neuromuscular factors, the loss of neural input to the muscles is ongoing and a lifelong process that is irreversible. When the body loses motor units that innervate several muscle fibers, the neurons that survived attempt to “adopt” muscle fibers. The lower number of motor units functional means the individual has decreased strength and muscle atrophy. The vastus lateralis in 43 male cadavers aged 15 to 83, this study showed total number of muscle fibers was reduced by 50% between the age…

This follow-up study would be a prospective randomized control trial much like the original. Because the original Petrie et al. study had some problems with how small their sample size was and with the size of the pool of participants, a follow-up study should use a larger number of and broader range of participants. At least 150 participants should be enrolled in the study to ensure that the data is more workable than in the original study. Although it might create a better pool of patients to…

disease after Lou Gehrig, a great American baseball player whose career unfortunately ended abruptly due to this incurable degenerative disease. ALS is the deterioration of motor neurons in the brain and spinal cord that leads to muscle weakness. This significant decrease in muscle strength eventually becomes paralysis, and the majority of those with this awful disease die from respiratory failure. This is the most common neuromuscular disease and affects 12,000 people annually and about 4 out…

Their key findings of defective myofibrillar organization was through assaying the muscle ultrastructure of fla mutants 48 hours post fertilization. The results are shown in Fig 1. above. These images show that sarcomerogenesis is absent in fast-twitch muscle tissues (Fig. 1D,F) and in cardiac tissue, but is very well defined in slow-twitch muscle tissue (Fig. 1H). Also, myosin bundles were never seen in fla mutant muscles, implying SMYD interferes with "early myosin assembly or stability" (Just…
