Skeletal muscle. One of the 3 major muscle types. It is a form of striated muscle tissue which is under the voluntary control of the somatic nervous system. Cardiac muscle. Also known as "heart muscle." It is an involuntary striated muscle that is located in the walls and histological foundation of the heart, specifically the myocardium. • The appendicular skeletal system (figure 1) consists of the shoulder girdle, skull, hip girdle, leg and arm bones. • The axial skeleton consists of the skull, vertebral column, ribs and sternum. The functions of the skeletal system are to act as a lever system, as surface area for attachment of muscle, tendons and ligaments, and to give. so by the contraction of skeletal muscle. There are more than skeletal muscles in the body. Collectively, they constitute 40% to 50% of our body weight. And, together with the scaffolding provided by the skeleton, muscles also determine the form and contours of our body. Contraction of individual muscle cells is ultimately re-.

Î Skeletal muscles are arranged in overlapping intricate layers: z Superficial muscles z Deep muscles Skeletal muscle Î Skeletal muscle is striated (striped), and excludes cardiac and smooth muscle. Î Skeletal muscle is under voluntary control. Î Each muscle is a separate organ. Î Each muscle is attached to bone by tendons that cross one.
