Question

the ______ deepens the socket of the hip joint and helps stabilize the joint.
multiple choice

fovea capitis
greater trochanter
lesser trochanter
acetabular labrum
ischial tuberosity

Explanation:

The acetabular labrum is a fibrocartilaginous rim that surrounds the acetabulum (the socket of the hip joint). It deepens the acetabulum, increasing the contact area between the femur (thigh bone) and the hip socket. This helps in stabilizing the hip joint by reducing the likelihood of dislocation and enhancing the joint's congruency. The other options:

• The fovea capitis is a pit on the head of the femur where a ligament attaches.
• The greater and lesser trochanters are bony projections on the femur for muscle attachment.
• The ischial tuberosity is a bony prominence on the ischium (part of the pelvis) that serves as a site for muscle attachment and weight - bearing when sitting.

Answer:

acetabular labrum
