2. It is made up of two hip bones called coxal bones. These coxal bones unite posteriorly with sacrum.
3. Coxal bone is a large irregularly shaped bone is made up of three parts – ilium, ischium and pubis.
4. At the point of fusion of ilium, ischium and pubis, a cavity called acetabulum is present that forms ball and socket joint with the thigh bone.
