ClipArt ETC

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.

The lower part of the large muscle that raises the heel during walking. P, the muscle, makes up most of the bulk of the calf of the leg. The weight of the body rests upon the bone W. In walking, as we raise the body in taking a step, we do it first by raising the heel with the muscle P, the pressure being on the ball of the foot, F. This muscle does here with the weight of the body what the muscles of your arms do to the load in a wheel barrow when you raise it by the handles.
