Your legs provide power for such common activities as walking, running, and jumping. They absorb the cummulative impact of those activities and also bear much of the body's weight. The thigh consists of the body's largest bone, the |femur|, which is grided on all sides by sets of powerful muscles. These sets works together to bend (flexion) and straighten (extension) as well a move outward (abduction) and inward (adduction). Some of these muscles are relatively long and participate in more than one type of movement.
