What Three Bones Form the Coxal Bone

Question

What three bones form the coxal bone?
A) ilium, ischium, coccyx
B) ilium, ischium, pubis
C) ilium, ischium, sacrum
D) none of the above

Accepted Answer

The ilium, ischium, and pubis are the three bones that fuse together to form the coxal bone (also known as the hip bone). The coccyx is a small bone at the bottom of the spine and the sacrum is a triangular bone just below the lumbar vertebrae, neither of which contribute to the formation of the coxal bone.
