The trigeminal, or fifth cranial nerve, is comprised of three major divisions: the ophthalmic, the maxillary and the mandibular. This largest of the cranial nerves conveys sensory information from the teeth, gingiva, mucous membranes of the head, the jaws, the muscles of mastication, the skin and the temporomandibular joints. It was hypothesised that the aetiopathology of the condition of headshaking involves abnormalities of either the structure, function or behaviour of the trigeminal nerve. Specifically it is believed that the second division of the trigeminal nerve, represented by the caudal nasal nerve (CNN) is involved. In addition it is. The trigeminal nerve is the largest cranial nerve. It transmits sensory information from the face and provides motor innervation to the muscles of mastication. A seg- mental approach should be used to evaluate the whole course of the trigeminal nerve. The MRI findings of the trigeminal brainstem nuclei and the cisternal. Special visceral efferent (SVE). Branchial motor to muscles of mastication.
