The Bones of the Lower Extremities

The bones of the lower extremities include the pelvic

girdle, which supports the trunk and provides attach-ment

for the legs. It consists of the paired hipbones or coxal

bones. Each hipbone consists of three fused parts: the ilium

(ILL-ee-um), the ischium (ISS-kee-um), and the pubis

(PYOO-bis). Other bones of the lower extremity include

the thigh, the kneecap, the shin, the calf, the ankle bones,

the foot, and the toes.

The pelvic girdle is actually made up of two hip or

coxal bones that articulate with one another anteriorly at
