The muscular system, which includes skeletal, smooth and cardiac muscles, is controlled by the nervous system (except, of course, for the cardiac muscle that functions involuntarily) and is responsible for movement. Consisting of 206 bones as well as joints, cartilage and ligaments, the skeletal system provides the strong, internal framework that supports our body. This Web guide spotlights a selection of Web sites on the muscular and skeletal systems that range from the simple to the complex.

The skeleton is the framework that maintains
our body system. The bones are the structures
through which movement is made. Skeletal
muscles cover the skeleton and give the body
the power to hold itself upright and to move.
