The Lower Limb

The femur—the bone of the upper leg—is the longest bone in the human body and one of the strongest.

The patella (knee cap) is the bone between the fibula and femur.

The tibia and the smaller fibula bones comprise the lower leg and articulate at the knee and ankle.

The human ankle and foot bones include tarsals (ankle), metatarsals (middle bones), and phalanges (toes).

The arches of the foot are formed by the tarsal and metatarsal bones; they dissipate impact forces and store energy for the subsequent step.
