During life the cavity is completed by the periorbita, a conical fibrous membrane, the apex of which is at- tached around the optic foramen. Ventral to the orbital cavity is the pterygo- palatine fossa. Its wall is formed by the pterygoid process, the perpendicular part of the palate bone, and the tuber maxillare. Its deep anterior recess contains three foramina. The upper one, the maxillary foramen, is the entrance to the in- Exiernal occipital pro- tuberance Occipital condyle â'â Paramastoid process â Condyloid fossa â Mastoid process Bulla ossea Postglenoid process â Glenoid cavity Temporal condyle Zygomatic process ~ Infratemporal fossa Zygomatic process of malar Pterygo-palati7ie fossa ^\â Maxillary recess Maxillary tuberosity Facial crest Hamulus of pterygoid Vomer Palatine bone {hori- zontal part) Ant. palatine foramen Palatine groove Palatine process of maxilla Fig. 49.âLine Drawing of Posterior Half of Base of Skull of Horse, Without Mandible.
