Question

multiple choice question

the acetabular labrum is part of which joint?

shoulder joint
hip joint
elbow joint

Explanation:

Identify the anatomical structure

The question asks to identify which joint contains the acetabular labrum. The term "acetabular" refers directly to the acetabulum, which is the deep, cup-shaped socket on the lateral aspect of the pelvis (hip bone).

Match structure to the correct joint

Using the Coxal Joint Anatomy knowledge point
The acetabulum articulates with the head of the femur to form the coxal joint, commonly known as the hip joint. The acetabular labrum is a ring of fibrocartilage that runs around the rim of the acetabulum, deepening the socket to stabilize the joint.

Evaluate the given options

• Shoulder joint: This joint contains the glenoid labrum, which deepens the glenoid cavity of the scapula.
• Hip joint: This joint contains the acetabular labrum.
• Elbow joint: This is a hinge joint formed by the humerus, radius, and ulna, and does not contain a labrum.

Answer:

• Shoulder joint
• Hip joint (Correct answer)
• Elbow joint
