In neuroanatomy, the trigeminal nerve (lit. triplet nerve), also known as the fifth cranial nerve, cranial nerve V, or simply CN V, is a cranial nerve responsible for sensation in the face and motor functions such as biting and chewing; it is the most complex of the cranial nerves.

Jul 25, 2023 · Like the ophthalmic branch, the maxillary division of the trigeminal nerve (CN V2) is a purely sensory entity that carries impulses from the midface. It has a middle meningeal branch that detects stimuli from the dura of the middle cranial fossa.

Feb 12, 2025 · The trigeminal nerve (CN V) is the fifth paired cranial nerve. It is also the largest cranial nerve. In this article, we shall look at the anatomy of the trigeminal nerve – its course, functions and clinical correlations. Explore, cut, dissect, annotate and manipulate our 3D models to visualise anatomy in a dynamic, interactive way.

Your trigeminal nerve, also known as cranial nerve 5 or CN V, is a large, three-part nerve in your head that sends signals from your brain to parts of your face, and vice versa. You have two trigeminal nerves — one on each side of your face.

Jan 24, 2025 · The trigeminal nerve is the fifth (CN V) 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 via the mandibular division (TA: nervus trigeminus or nervus cranialis V).

The three terminal branches of CN V innervate the skin, mucous membranes and sinuses of the face. Their distribution pattern is similar to the dermatome supply of spinal nerves (except there is little overlap in the supply of the divisions). Only the mandibular branch of CN V has motor fibres.

May 1, 2023 · The trigeminal nerve (cranial nerve V; CN V) is a mixed sensory and motor nerve. It supplies the face via three branches of the nerve: from rostral to caudal, the sensory ophthalmic nerve (V1), the sensory maxillary nerve (V2), and the …

Nov 3, 2023 · The maxillary nerve is one of the branches of the trigeminal nerve, otherwise known as the fifth cranial nerve (CN V). Supplying sensory innervation to certain parts of the face, the mucosa of the nose, together with the teeth , this nerve allows you to feel that annoying fly landing underneath your eye or that annoying pain caused by your dentist.

Nov 3, 2023 · The ophthalmic nerve is one of the branches of the trigeminal nerve, otherwise known as the fifth cranial nerve (CN V). Supplying sensory innervation to certain parts of the eye , the lacrimal gland, some paranasal sinuses, meningeal layers, and the scalp this nerve allows you to blink quickly when dust gets in the eye, for example.
