The human body has more than 600 major muscles. About 240 of them have specific names. There are two main types of muscles (1) skeleton muscles and (2) smooth muscles. A third kind of mudcles called Cardiac Muscle has characterestics of both skeleton and smooth muscles. It is found only in the heart. Skeleton muscles help hold the bones of the skeleton together and give the body shape. They also make the body move. Skeleton muscles make up a large part of the legs, arms, abdomen, chest, neck and face. These muscles vary greatly in size, depending on the type of job they do. For e.g., eye muscles are small and fairly weak, but the muscles of the thigh are large and strong.
