This document lists the major muscles that move the lower extremity, including the hip/thigh, leg, and foot. For each muscle or muscle group, it identifies the origin and insertion points. The muscles are grouped based on their action, such as flexors and extensors of the hip, knee, and foot. Over 25 muscles in total are identified and briefly described.
