The hip joint is scientifically referred to as the acetabulofemoral joint. The joint consists of 2 articulating bones: the head of the femur and acetabulum of the pelvis. Like the shoulder joint, it is referred to as a ball and socket joint.
The primary function is to support the weight of the body in both static (e.g. standing) and dynamic (e.g. walking, running) postures. Its secondary function is mobility; as it is a ball and socket joint it moves in all directions. It is an extremely secure joint having numerous ligaments and muscles that cross it.
