The lower limb is a complex, weight‑bearing apparatus that enables locomotion, balance, and posture. It is composed of the pelvic girdle, thigh, leg, and foot. Because it must support the entire body mass, its skeletal, muscular, neuro‑vascular, and lymphatic structures are highly organized for strength, stability, and precise movement.
