Lower limb
The lower limb supports body weight and locomotion through the pelvic girdle, hip, thigh, leg and foot. The hip favors stability while the ankle and foot adapt to the ground.

Skeletal chain
The acetabulum articulates with the femoral head. The femur meets tibia at the knee; tibia and fibula lead toward tarsals, metatarsals and phalanges.
Functional groups
Anterior thigh muscles chiefly extend the knee; posterior thigh muscles contribute to hip extension and knee flexion, while posterior leg muscles help plantarflex the ankle.
Major nerves
The femoral nerve predominantly supplies the anterior thigh. The sciatic nerve divides into tibial and common fibular branches, supplying much of the leg and foot.
Arterial pathway
External iliac becomes femoral under the inguinal ligament. Popliteal branches supply the leg through anterior and posterior tibial systems.
