Which of the following structures is formed by parts of the ilium, ischium, and pubis?
A)Obturator foramen
B)Acetabulum
C)Pubic arch
D)Greater sciatic notch
E)Iliac fossa

Accepted Answer

The acetabulum is a cup-shaped cavity in the hip bone that receives the head of the femur to form the hip joint. It is formed by parts of the ilium, ischium, and pubis. The obturator foramen is a large hole in the hip bone formed by the ischium and pubis. The pubic arch is the angle formed by the pubic bones below the pubic symphysis. The greater sciatic notch is a deep indentation in the posterior side of the ilium. The iliac fossa is a large, smooth, concave surface on the internal surface of the ilium.
