What is the adjectival form of acetabulum?

• A. Acetabular
• B. Acetabulum
• C. Trochanteric
• D. Femoral

Answer: (A)

The main idea here is how to form the adjective that describes something related to a body part. For the hip socket, the correct descriptor is acetabular, which means pertaining to the acetabulum. This term is routinely used in phrases like acetabular fracture or acetabular labrum, indicating conditions or features of the hip socket itself. The noun acetabulum names the hip socket, so it wouldn’t function as an adjective here. Trochanteric relates to the trochanters of the femur, not the acetabulum, and femoral refers to the femur. So the adjective that correctly describes anything of or pertaining to the acetabulum is acetabular.
