* one in front, the [[pubic arch]], formed by the convergence of the [[inferior ramus of the ischium|inferior rami]] of the [[ischium]] and [[pubis (bone)|pubis]] on either side.
* The other notches, one on either side, are formed by the [[sacrum]] and [[coccyx]] behind, the [[ischium]] in front, and the [[ilium (bone)|ilium]] above; they are called the [[sciatic notches (disambiguation)|sciatic notches]]; in the natural state they are converted into [[foramina]] by the [[sacrotuberous]] and [[sacrospinous ligament]]s.
