Each branch provides sensation to specific areas of the face — ophthalmic cornea, medial canthus of the eye, planum of the nose, nasal septal mucosa , maxillary maxillary area, lateral canthus of the eye , mandibular mandibular area.
All branches are responsible for sensory innervation of the face cutaneous elements of the face as well as the cornea, mucosa of the nasal septum and mucosa of the oral cavity. The cell body of the sensory part of CN V lies in the trigeminal Gasserian ganglion in the trigeminal canal in the petrous temporal bone.
Axons from these cell bodies enter into the trigeminal nerve proper to enter the pons at the level of the middle cerebellar peduncle. From here, fibers course caudally on the lateral side of the medulla in the spinal tract of cranial nerve V. This is a large structure that extends from the pons through the medulla and continues caudally into the first cervical spinal cord segment as the dorsolateral fasiculus Lissauers tract.
Illustrated anatomical parts with images from e-Anatomy and descriptions of anatomical structures. The Maxillary Nerve [Vb; V2] n. It begins at the middle of the semilunar ganglion as a flattened plexiform band, and, passing horizontally forward, it leaves the skull through the foramen rotundum, where it becomes more cylindrical in form, and firmer in texture.
It then crosses the pterygopalatine fossa, inclines lateralward on the back of the maxilla, and enters the orbit through the inferior orbital fissure; it traverses the infraorbital groove and canal in the floor of the orbit, and appears upon the face at the infraorbital foramen. At its termination, the nerve lies beneath the Quadratus labii superioris, and divides into a leash of branches which spread out upon the side of the nose, the lower eyelid, and the upper lip, joining with filaments of the facial nerve.
