maxillary nerveAbbreviation: CN V2
The middle trunk of the trigeminal cranial nerve. The maxillary nerve is purely sensory; its major branches are the pterygopalatine, posterior superior alveolar, zygomatic, and infraorbital nerves, which innervate the palate, nasal cavity, upper teeth, and the skin of the lower eyelids, checks, nose, and upper lip. COURSE: The maxillary nerve leaves the skull, and enters the pterygopalatine fossa, via the foramen rotundum.
