Preferred Label : middle cranial fossa;
Uberon definition : The compartment containing the anterior extremities and half the inferior surface
of the temporal lobes (TEMPORAL LOBE) of the cerebral hemispheres. Lying posterior
and inferior to the anterior cranial fossa (CRANIAL FOSSA, ANTERIOR), it is formed
by part of the TEMPORAL BONE and SPHENOID BONE. It is separated from the posterior
cranial fossa (CRANIAL FOSSA, POSTERIOR) by crests formed by the superior borders
of the petrous parts of the temporal bones[MESH]. The middle fossa, deeper than the
anterior cranial fossa, is narrow medially and widens laterally to the sides of the
skull. It is separated from the posterior fossa by the clivus and the petrous crest.
It is bounded in front by the posterior margins of the lesser wings of the sphenoid
bone, the anterior clinoid processes, and the ridge forming the anterior margin of
the chiasmatic groove; behind, by the superior angles of the petrous portions of the
temporal bones and the dorsum sellC&; laterally by the temporal squamC&, sphenoidal
angles of the parietals, and greater wings of the sphenoid. It is traversed by the
squamosal, sphenoparietal, sphenosquamosal, and sphenopetrosal sutures[WP].;
