The cranial nerve CN V is a mixed nerve that consists primarily of sensory neurons. It exits the brain on the lateral surface of the pons, entering the trigeminal ganglion within a few millimeters. Three major branches emerge from the trigeminal ganglion.
The first division V1, the ophthalmic nerve exits the cranium through the superior orbital fissure, entering the orbit to innervate the globe and skin in the area above the eye and forehead. The second division V2, the maxillary nerve exits through a round hole, the foramen rotundum, into a space posterior to the orbit, the pterygopalatine fossa.
It then re-enters a canal running inferior to the orbit, the infraorbital canal, and exits through a small hole, the infraorbital foramen, to innervate the skin below the eye and above the mouth.
The third division V3, the mandibular nerve exits the cranium through an oval hole, the foramen ovale. The third division also has an additional motor component, which may run in a separate fascial compartment. Most fibers travel directly to their target tissues. Sensory axons innervate skin on the lateral side of the head, the tongue, and the mucosal wall of the oral cavity.
Motor fibers innervate the muscles that are attached to the mandible. Some sensory axons enter in the mandible to innervate the teeth and emerge from the mental foramen to innervate the skin of the lower jaw. Trois branches majeures apparaissent du ganglion de Gasser.
