Cruciform eminence

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


 * The upper two fossae are triangular and lodge the occipital lobes of the cerebrum.
 * The lower two are quadrilateral and accommodate the hemispheres of the cerebellum.

At the point of intersection of the four divisions of the cruciate eminence is the internal occipital protuberance.
