lesser wing above (1) and a greater wing below (2). Its eyes (3) are openings of the sphenoid sinus into the upper nasal cavity. Near each of the bird's eyes lies an optic foramen (4) (which transmits the optic nerve). The superior orbital fissure (5) (which transmits cranial nerves 3,4;5, and 6) is the super ior armpit between the wings. The round foramen, or foramen rotundum (6), (which transmits the seeond, maxillary, branch of cranial nerve 5), and inferior orbital fissures (7) form the inferior armpit below the greater wing. The feet have two giant claws - the lateral (8) and medial (9) pterygoid plates. The pterygopalatine fossa.
