WebbStructure of Skeletal Muscle. A whole skeletal muscle is considered an organ of the muscular system.Each organ or muscle consists of skeletal muscle tissue, connective tissue, nerve tissue, and blood or vascular tissue.. Skeletal muscles vary considerably in size, shape, and arrangement of fibers. They range from extremely tiny strands such as … The primary function of muscle is contraction. Following contraction, skeletal muscle functions as an endocrine organ by secreting myokines – a wide range of cytokines and other peptides that act as signalling molecules. Myokines in turn are believed to mediate the health benefits of exercise. Myokines are secreted into the bloodstream after muscle contraction. Interleukin 6 (IL-6) is the most studied myokine, other muscle contraction-induced myokines include BDNF, FGF21, and SP… WebbFigure 10.8 Contraction of a Muscle Fiber A cross-bridge forms between actin and the myosin heads triggering contraction.
