Clivus

The clivus is the sloping midline surface of the occipital bone anterior to the foramen magnum. Specifically it is located in the basiocciput. At the clivus, the occipital bone has articulations with the sphenoid and petrous part of temporal bone1.

Inferiorly the clivus is flanked be the rounded prominances of the jugular tubercles which represents the fusion of the bassiocciput with the lateral jugular parts of the occipital bone.

At the level of the jugular tubercles, the clivus is occupied by the medulla1.

Above the jugular tubercles, the clivus is wider and occupied by the pons

Anatomically it is also closely related to the basilar venous plexus and pontine cistern.
