Anatomical terms of bone

The internal surface of the occipital bone is deeply concave and divided into four fossae by a cruciform eminence (or cruciate eminence).

  • The superior two fossae, called cerebral fossa, are triangular and lodge the occipital lobes of the cerebrum.
  • The inferior two fossae, called cerebellar fossa, are quadrilateral and accommodate the hemispheres of the cerebellum.

The superior and inferior fossae are separated by a transverse groove. At the point of intersection between all four fossae is the internal occipital protuberance.
