In the hip region, Structure G corresponds to which anatomical landmark?

• A. Acetabulum
• B. Ischial tuberosity
• C. Greater trochanter
• D. Lesser trochanter

Answer: (B)

The structure is a palpable, posterior-inferior bony prominence of the pelvis known as the ischial tuberosity, the so-called sitting bone. It sits at the lower, back part of the pelvis and is easily felt when you sit or palpate through the gluteal region. This location makes it the best match for Structure G in the hip area, since the other options lie in different places: the acetabulum is the hip socket higher and more lateral; the greater trochanter is on the proximal femur around the outer side; the lesser trochanter is on the inner, posterior aspect of the femur just below the neck.
