THE SKULL 53 mandible. This fossa is bounded caudally by the prominent postmandibular process (;;/). All that portion of the lateral surface of the skull which lies craniodorsad of the lambdoidal ridg^c may be divided (exclud- ing^ the zygomatic arch) into three main parts, the temporal fossa, the orbital fossa, and the face. The boundaries of the temporal fossa have been given. The orbital fossa is bounded

The orbital fossa may be considered to end caudally and ventrally at the level of the optic foramen (zv); ventrad of it are certain smaller fossjE. Immediately ventrad is the long external pterygoid fossa (/), from which arises part of the external pterygoid muscle. This fossa begins at the sphenopalatine foramen (q) and extends caudad to the <:)rbital fissure (r); it is separated by a ridge from the orbital fossa. Caudoventrad of the external
