trigeminal

 [tri-jem´ĭ-nal]
triple.
pertaining to the fifth cranial nerve (trigeminal nerve).
trigeminal nerve the fifth cranial nerve; it arises in the pons, is composed of sensory and motor fibers, and has three divisions: ophthalmic, maxillary, and mandibular. (See anatomic Table of Nerves in the Appendices.) The ophthalmic division supplies sensory fibers to the skin of the upper eyelid, side of the nose, forehead, and anterior half of the scalp. The maxillary division carries sensory impulses from the mucous membranes of the nose, the skin of the cheek and side of the forehead, and the upper lip and upper teeth. The mandibular division carries sensory impulses from the side of the head, chin, mucous membrane of the mouth, lower teeth, and anterior two-thirds of the tongue. (This nerve is sometimes called the great sensory nerve of the head.) The motor fibers are part of the mandibular branch and supply several of the muscles of chewing. Neuralgia of this nerve is the condition known as tic douloureux.
Areas of innervation by each of the three branches of the trigeminal nerve.

trigeminal nerve

n.
Either of the fifth pair of cranial nerves, being the chief sensory nerve of the face and the motor nerve of the muscles of chewing and having sensory and motor functions in the teeth, mouth, and nasal cavity. Also called trigeminus.

trigeminal nerve

The 5th of the 12 pairs of cranial nerves and the sensory nerve of the face. Each trigeminal nerve divides into three main branches, the ophthalmic, the maxillary and the mandibular nerves, which then branch to supply the corresponding parts of the face.

trigeminal nerve

the fifth cranial nerve of vertebrates, usually possessing opthalmic, mandibular and maxillary branches.

The consecutive and immediate appearance of symptoms related to HZO and MS in a 10-week period after the onset of skin lesions strongly suggests that VZV reactivation in the first branch of the trigeminal nerve immunologically triggered the onset of MS.Ocular complications, including optic neuritis, are rare in patients with pediatric herpes zoster, and their symptoms cannot be easily noticed in children.
The infraorbital nerve is the terminal branch of the maxillary division of the trigeminal nerve and carries sensory information from the lower eyelid, one side of the nose, and the upper lip.
In this study, we report a rare case of corneal epithelial defects that occurred on the following day of a trigeminal nerve block for postherpetic neuralgia, and the process of loss and regeneration of the corneal subbasal nerve fibers was observed using the Rostock Cornea Module of the Heidelberg Retina Tomograph II (RCM HRT II, Heidelberg Engineering, Carlsbad, CA).
In our patient's case, we hypothesize that the pain and trigeminal-autonomic features may be due to direct contact between the lesion and the trigeminal nerve or secondary to local edema and inflammation.
Trigeminal Neuralgia (TN), often described as one of the most painful conditions to live with, is caused primarily by the compression of the fifth cranial nerve (trigeminal nerve).
