Hip

The hip is a ball and socket joint. The ball portion of the joint is called the femoral head, and is part of the upper leg bone (femur). The socket portion is called the acetabulum, and is part of the pelvic bone. The femoral head (ball) fits into the acetabulum (socket) and moves within its natural fluid, called synovial fluid, which helps to lubricate the joint during motion.

In a healthy hip joint, the surface of the bones where the ball and socket rub together are very smooth and covered with a tough protective tissue called cartilage quid.
