The pelvic girdle includes two coxal bones that articulate with each other anteriorly at the symphysis pubis and with the sacrum posteriorly. Together, the pelvic girdle, sacrum, and coccyx comprise the pelvis. The pelvis, in turn, provides support for the trunk of the body and provides attachments for the lower limbs.
The bones of the lower limb form the framework of the thigh, leg, and foot. Each limb includes a femur, a patella, a tibia, a fibula, and seven tarsals, five metatarsals, and fourteen phalanges.
