The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles.he muscular system in vertebrates is controlled through the nervous system, although some muscles (such as the cardiac muscle) can be completely autonomous.
Organization of Skeletal Muscle. Our bodies contain numerous skeletal muscle organs-for example, the biceps brachii of the arm and the gastrocnemius of the leg. The muscles that move and support our body are attached to bones at each end by what we call tendons.he muscle fiber membrane is called the sarcolemma. Skeletal muscle cells or fibers are composed of hundreds to thousands of contractile organs that we call myofibrils. Each myofibril runs the length of the muscle fiber. Remember, muscle fibers run the length of the muscle organ.
