Uberon definition : Part of the cranium, the clivus is a shallow depression behind the dorsum sellC& that
slopes obliquely backward. It forms a gradual sloping process at the anterior most
portion of the basilar occipital bone at its junction with the sphenoid bone. On axial
planes, it sits just posterior to the sphenoid sinuses. Just lateral to the clivus
bilaterally is the foramen lacerum which contains the internal carotid artery, proximal
to its anastamosis with the Circle of Willis. Posterior to the clivus is the basilar
artery. The clivus supports the upper part of the pons.;
