What bones contribute to the hip joint? Name all parts of the hip.
The bones that contribute to the hip joint are the femur and the os coxae (hip bone), which consists of the ilium, ischium, and pubis.
The parts of the hip joint include:
1. Femoral head: The spherical top of the femur that fits into the acetabulum of the hip bone.
2. Acetabulum: The cup-shaped socket on the lateral side of the hip bone that the femoral head articulates with.
3. Labrum: A ring of fibrocartilage attached to the rim of the acetabulum that deepens the socket and provides stability to the hip joint.
4. Joint capsule: A thick, fibrous envelope that encloses the hip joint and provides support to the joint.
5. Ligaments: There are several ligaments that support the hip joint, including the iliofemoral ligament, pubofemoral ligament, and ischiofemoral ligament.
6. Synovial membrane: A membrane that lines the inner surface of the joint capsule and secretes synovial fluid, which lubricates and nourishes the joint.
