The skeleton of the lower limb (or lower extremity) consists of the pelvis or pelvic skeleton (also known as pelvic girdle) and the free lower extremity, which has three parts: thigh, leg and foot.

• The pelvis is made up from two hip bones, sacrum, and coccyx.
• The skeleton of the thigh is formed by a single bone - the femur, and the lower leg consists of two bones - tibia and fibula.
• Between the thigh and the leg in the anterior knee region lies the largest sesamoid bone in the human body, the patella.
• The final part of the lower limb is the foot, and the skeleton of the human foot is formed by about 26 bones.
