The isometric phase of muscle contraction occurs when the length of the muscle body is constant, with no visible shortening, as the tension increases (Kroeker, 2017). Isometric tension is the first phase of the SEC model of contraction, in which the cross-bridges formed by actin and myosin filaments shorten, but add tension only to SEC (Kroeker, 2017). The isotonic phase of muscle contraction.
A majority of muscle disease cause muscle weakness, fatigue, and deterioration of muscle fibers. Disorders which can affect the muscular system are usually due to an immune deficiency, poison, or genetic cause. Disorders of the muscles that are connected to the immune system can often lead to tumors. Cancer in the muscular system is rarely heard of, but they do exist.

Essay on Muscle Contraction. Muscle contraction is the process whereby the muscle is contracted. Histologically, the muscle tissue is composed of muscle fibers that are polynuclear, elongated cells. The cells in turn contains muscle fibers constructed of sarcomeres. A sarcomer is composed of actin filaments, myosinfilament with several proteins. The students who are trying to prepare a good.
A muscle contracts when the thin filaments slide over the thick filaments toward the center of each sarcomere. During contraction, the (1) move closer together and the (2) gets smaller. At rest, (3) molecules surround the thin filaments and prevent myosin crossbridges from binding with actin.
