Trigeminal nerve anatomy. The trigeminal nerve the fifth cranial nerve or simply cn v is a nerve responsible for sensation in the face and motor functions such as biting and chewing. It is both large and complicated and has multiple brainstem nuclei sensory and motor as well as many interconnections with other cranial nerves. Ophthalmic division cn v1 or va maxillary division cn v2 or vb mandibular division cn v3 or vc.

It gains access into the orbit via the superior orbital fissure fig. The frontal nerve the lacrimal nerve and the nasociliary nerves converge in. The ophthalmic nerve passes forward in the lateral wall of the cavernous sinus.

Join us in this video where we discuss the trigeminal nerve cranial nerve v. The three sensory nerve branches of the trigeminal nervethe ophthalmic nerve. The trigeminal nerve cn v is the fifth paired cranial nerve.

Trigeminal nerve anatomy and function. The trigeminal nerve roots and ganglion like those of other cranial nerves. It supplies sensations to the face mucous membranes and other structures of the head.

The trigeminal nerve has three different divisions. It is the largest of the cranial nerves. The motor section of the trigeminal nerve has a nucleus point situated in the pons innervating the masticating muscles and also the tensor muscle in the tympanic membranes of the ear.

It is also the largest cranial nerve. It is the motor nerve for the muscles of mastication and contains proprioceptive fibers. The trigeminal nerve trifurcates into ophthalmic maxillary and mandibular nerves distal to the trigeminal ganglion.

In this article we shall look at the anatomical course of the nerve and the motor sensory and parasympathetic functions of its terminal branches. The trigeminal nerve is the biggest cranial nerve and has sensory as well as motor divisions. The trigeminal nerve is the largest and most complex of the 12 cranial nerves cns.

The trigeminal nerve is the fifth cranial nerve and its primary role is relaying sensory information from the face and head although it does provide motor control to the muscles of mastication. The acronym mom can be used to recall the three. We go into great detail on the origin course and structures supplied by the trigeminal nerve.
