Human Muscular System

This human anatomy ClipArt gallery offers 242 illustrations the human muscular system. This includes both human skeletal muscle and human smooth and cardiac muscle. Human skeletal muscles (also known as striped, striated, or voluntary muscle) are those muscles that attach to bones and are involved in voluntary movements. Smooth muscles (also known as non-striated or involuntary muscle) are found lining the surface of internal organs such as the stomach, and cardiac muscles are those muscles specific to the heart. Both smooth and cardiac muscles are involuntarily controlled by the autonomic nervous system.
