    SPHENOID BONE. 1. Great wing. 2. Lesser wing, attached by two roots. 3. Pterygoid process. 4. Pituitary fossa, receives the pituitary gland or body. 5. Dorsum Ephippii. 6. Posterior clinoid processes, attach the ten- torium ceiebelli. 7. Olivary process upon which the optic com- missure lies. 8. A portion of the superior surface of the body in front of the olivary process. 9. Eostrum, articulates with ate of the vomer. 10. Pterygopalatine canal, transmits pterygo- palatine vessels and nerve. 11. Groove in which lie the cavernous sinus and the internal carotid artery. 12. Posterior surface, articulates with the basi- lar process of the occiput. 13. Sphenoid cells. 14. Sphenoidal turbinated bone. 15. Cerebral surface of great wing. 16. Foramen spinosum, transmits middle me- ningeal artery into skull. 17. Foramen ovale, transmits inferior maxillary nerve, or third division of fifth, out of the skull, and a small artery, the meningea- parva, into the skull. 18. Foramen rotundum, through which the superior maxillary nerve, or second division of fifth, leaves the skull. 19. Foramen lacerum anterius, or sphenoidal fissure, through which the third, fourth, ophthalmic (first division of fifth) and sixth nerves pass from the skull into the orbit, and the ophthalmic vein returns. 20. Orbital surface of great wing, quadrilateral in form, contributes to outer wall of orbit. 21. External surface of great wing, its upper portion belongs to temporal fossa, and giveB origin to temporal muscle. 22. External surface of great wing, its lower portion belongs to zygomatic fossa, and gives origin to the external pterygoid muscle. 23. Spine of the sphenoid, attaches internal lateral ligament of lower jaw and 0. laxator tympani muscle. 24. Triangular surface for articulation with the frontal bone. 25. Line of articulation of the lesser wing with the ethmoid bone. 26. Anterior clinoid process, attaches tentorium cerebelli. 27. Lower root of lesser wing. 28. Optic foramen, transmits the optic nerve and ophthalmic artery. Around the front of this foramen the muscles of the eye arise. 29. Anterior orifice of Vidian canal, transmits Vidian nerve and artery. 30. Posterior orifice of Vidian canal. 31. External surface ol external pterygoid plate and 0. external pterygoid muscle. 32. Internal surface of external pterygoid plate and 0- internal pterygoid muscle. 33. Internal pterygoid plate, at the base of which an elliptical depression, the scaphoid fossa, gives origin to the tensor palati muscle. 34. Hamular process, around which the tensor palati muscle turns. PALATE BONE. 1. Anterior border of horizontal plate, articu- lates with the palatine process of superior maxilla. 2. Internal border, articulates with fellow. 3. Posterior border. 4. Posterior nasal spine. 5. Transverse ridge. I. tensor palati. 6. Posterior palatine canals, transmit posterior palatine vessels and nerves. 7. External surface of vertical plate of the palate bone, articulates with superior maxilla. 8. Inferior turbinated ridge for inferior spongy bone. 9. Middle turbinated ridge for middle spongy bone. 10. Orbital process, presents five surfaces; an- terior articulates with superior maxilla j posterior articulates with sphenoidal tur- binated ; internal articulates with ethmoid; superior contributes to orbital fossa; external contributes to spheno-maxillary fossa. 11. Sphenoidal process articulates superiorly with body of the sphenoid; inferiorly con- tributes to nares; externally contributes in part to the spheno-maxillary fossa, and in part overlaps the internal pterygoid plate. 12. Spheno-palatine notch or foramen transmits spheno-palatine vessels and nerves into the nose. 13. Tuberosity of the palate bone. 14. Groove contributing to pterygoid fossa. 15. Groove for internal pterygoid plate. 16. Rough margin for external pterygoid plate.
