Muscular system

The two main neck muscles are the sternocleidomastoid and the trapezius, and are responsible for the gross motor movement in the muscular system of the head, neck and shoulders. The sternocleidomastoid muscle is a paired muscle, located at the front and on each side of the neck. It is one of the largest and most superficial cervical muscles. The primary actions of the muscle are rotation of the head to the opposite side and flexion of the neck. The trapezius is one of the biggest shoulder and…

Enhanced muscular strength and endurance can lead to improvements in the areas of performance, injury prevention, body composition, self-image, lifetime muscle and bone health, and metabolic health. Most important, greater muscular strength and endurance reduce the risk of premature death (Reuter 101). Muscular performance can be broken down into two components, strength and endurance. “Muscle strength is the ability to exert a maximal amount of force for a short period of time. Muscle endurance…

Flexing in the mirror for self-confidence to building muscle for impressing the ladies, little do these individuals realize how their muscle works while they pump the iron. The muscular system is the network of tissues that help controls movement throughout the body using contraction and relaxation of different muscles. This system is divided into two classes, skeletal (voluntary) and smooth (involuntary). Skeletal muscles are known as voluntary because the mind allows a person to control their…

a very inexpensive form of exercise. All that it takes is time and effort. A person can run almost anywhere, a park, a trail, a track, a neighborhood or even on a treadmill. Running is an excellent exercise for the cardiovascular and respiratory systems. It focuses on the leg muscles, toning and strengthening them. If a person is not sure how to start a running program, there are options for them. Couch to 5K is a program that gives a person a starting point and lets them build up to running a…

of lysosomes to breakdown glycogen into glucose and causes the glycogen to build up inside the lysosome (Pompe, 2010). The glycogen build up has specific effects on the muscles of the body I chose Pompe Disease because of its effects on the muscular system. Also, I feel that, because of its specific effects directly on the lysosomes of cells causing it to be a rare disorder, it does not receive enough attention.…

“A muscle is a tissue composed of cells or fibres, the contraction of which produces movement in the body.” (Dictionary) There are three different types of muscle; voluntary skeletal muscle, involuntary smooth muscle and cardiac muscle. Muscles have many different functions within the body. One function of muscle is movement. It is the only tissue in the body which is able to contract and therefore can move more than other body parts. Another function is the maintenance of posture. The muscles…

Case Study: Hereditary Canine Spinal Muscular Atrophy Genetic Background Hereditary canine spinal muscular atrophy (HCSMA) is proven to be an autosomal-dominate disease that affects most noticeably the Brittany spaniel (Pinter MJ, Waldeck RF, Wallace N, & Cork LC, Motor Unit Behavior in Canine Motor Neuron Disease, 1995). HCSMA originated as a spontaneous mutation in the Survivor Motor Neutron gene found in the purebred Brittany spaniel population (Ericsson. A & Rubin. C, 2012). Due to the…

Katch L, define fatigue as the inability to maintain submaximal or maximal force output as a result of sustained muscle activity within a given period of time (2010). The onset of fatigue is related to four major components: change in central nervous system chemical composition, reduction in fuel and nutrients content supply to muscle tissue, decreased pH as a result of accumulating metabolites and disruption of muscle action potentials (MAP) within the neuromuscular junction (McArdle et al.).…

diseases like, muscular dystrophy, Anemia, and the ones that are having surgical repairs. This drug should be used precisely because an extra dose or a smaller dose could cause all the harm to a person, and that is why they are not meant for recreational athletes because it will clutter their hormones and cause imbalances which will lead to other problems. I believe that the anabolic steroids are such a great treatment owing to the fact that it rebuilds a whole person’s muscular system to keep…

Do you know what a muscle fiber is? A muscle fiber is a single muscle tissue cell. There are three types of muscles. The skeletal, visceral, and cardiac. The skeletal muscles are voluntary, while the visceral muscles are involuntary. In this essay, I will be explaining muscles. There are many interesting facts about the muscles. Muscles are the "engine" that your body uses to propel itself. Did you also know that there are three primary muscle fiber types in humans? Type I, Type IIA, Type…
