Cerebral surface
Facies cerebralis
Definition
The cerebral surface (Facies cerebralis) or medial surface of the squamous part of the temporal bone is the smooth concave surface that contributes to form the wall of the cerebral cavity. It is surrounded by a broad rough strip, meant to connect it to the neighboring bones. The extend of this cerebral surface varies according to the species:
In Bulls, it is absent: the parietal bone covers the medial surface of the squamous part and comes nearly in contact with the petrous part of the temporal bone and the sphenoid bone.
In Sheeps, Goats and Pigs, it is narrow, but covers most of the rostral surface of the petrous part and enters in the constitution of the cerebrocerebellar crest by a particular relief (Crista tentorica) that replaces the petrous crest.
In other species, the cerebral surface shows the imprints of vessels and cerebral gyri. Barone
