Question

multiple choice question

what is the structure of the hip joint indicated in the figure?

• fovea capitis
• glenoid cavity
• acetabular labrum
• medial meniscus

Explanation:

Identify the anatomical structure

Using the Acetabular Labrum and Coxal Joint Anatomy knowledge points:

• The diagram shows a lateral view of the right hip joint with the head of the femur disarticulated from the acetabulum.
• The pointer line originates from the fibrocartilaginous ring that rims the outer margin of the acetabular cavity.
• This ring of fibrocartilage deepens the socket of the hip joint and is anatomically defined as the acetabular labrum.

Evaluate the other choices

• Fovea capitis: A small pit on the head of the femur, which is visible on the spherical head to the right but is not pointed to.
• Glenoid cavity: Located in the shoulder joint (scapula), not the hip joint.
• Medial meniscus: A crescent-shaped cartilage structure located in the knee joint, not the hip joint.

Answer:

• O Fovea capitis
• O Glenoid cavity
• O Acetabular labrum (Correct answer)
• O Medial meniscus
