Did you know that . . .

   Some 650 muscles cover the body's skeleton? Muscles do more than shape and define the contours of our bodies. They are responsible for all of the body's movements. Muscles are attached to bones by tough, hard tissue called tendons. In response to instructions from the brain, muscles contract and pull on the bones and movement occurs. Usually skeletal muscles work in groups. Even aseemingly simple task such as taking one step involves about 200 muscles! Some muscles lift and move your leg forward, while others in the back, chest, and abdomen help keep you from losing your balance during the motion.
