Which structure forms the socket for the femoral head in the hip joint?

• A. Acetabular labrum
• B. Acetabulum
• C. Femoral head
• D. Glenoid cavity

Answer: (B)

The socket for the femoral head in the hip joint is the acetabulum, a cup-shaped portion of the pelvis formed by parts of the ilium, ischium, and pubis. The acetabular labrum is a fibrocartilaginous rim that deepens this socket and helps seal the joint, enhancing stability, but the socket itself is the acetabulum. The femoral head is the ball that fits into this socket, and the glenoid cavity is the socket of the shoulder, not the hip.
