Pectoralis minor muscle

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…

described as decline or regression in body ability to adapt to physical insults and environmental stressors. And that is because of the physiological changes associated with aging like decrease in muscle and bone mass, decreased vital capacity of lungs and decreased nerve conduction velocity.…

Chordate Dissection and Anatomy In this lab, a dissection was performed on a mouse, a frog, and a dogfish shark, and the anatomy was observed and noted. The three animals have some similarities and differences. The mouse, frog, and dogfish shark are all similar in that they all have closed circulatory systems. But the three animals have different types of hearts. The mouse has a four chambered heart, the frog has a three chambered heart, and the dogfish shark has a two chambered heart. The…

Exercise benefits people in many ways from physical to mental health. With the health conscious society we live in, there are more people now than ever that look to daily exercise to maintain overall health. It has been used to battle childhood obesity, increase energy levels as well as improve heart health. The versatile benefits of exercise has caused it to become a recent trend. Childhood obesity is a major problem in the United States due to the availability of junk food as well as the lack…
