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.
