maxillary nerve CN V2 max·il·lar·y nerve [CN V2]the second division of the trigeminal nerve, passing from the trigeminal ganglion in the middle cranial fossa through the foramen rotundum into the pterygopalatine fossa, where it gives off ganglionic branches to the pterygopalatine ganglion and continues forward to give off the zygomatic nerve and enter the orbit, where it continues as the infraorbital nerve. Its sensory fibers are distributed to the skin and conjunctiva of the lower eyelid, the skin and mucosa of the upper lip and cheek, the palate, upper teeth and gingiva, the maxillary sinus, wings of the nose, and posterior/interior nasal cavity.
