2017年12月22日 · The ophthalmic nerve (CNV1) is a terminal branch of the trigeminal nerve (along with the maxillary and mandibular nerves). It provides sensory innervation to the skin, mucous membranes and sinuses of the upper face and scalp.

2023年11月3日 · The trigeminal nerve (cranial nerve V) is a mixed nerve, meaning that it is made of both fiber types: descending motor (efferent) fibers and afferent neural fibers that belong to the general somatic afferent system.

The ophthalmic nerve (CN V1) is a sensory nerve of the head. It is one of three divisions of the trigeminal nerve (CN V), a cranial nerve. It has three major branches which provide sensory innervation to the eye, and the skin of the upper face and anterior scalp, as well as other structures of the head.

2023年7月25日 · The trigeminal nerve is a mixed cranial nerve that has both sensory and motor functions. There are three divisions of the trigeminal nerve: Ophthalmic division (CN V1 or Va), Maxillary division (CN V2 or Vb), Mandibular division (CN V3 or Vc). The acronym MOM can be used to recall the three branches of the trigeminal nerve.

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.

The nerve has three divisions: the ophthalmic, maxillary, and mandibular nerves (Figure 61.1). The innervation includes the cornea and conjunctiva of the eye; mucosa of the sinuses, nasal and oral cavities; and dura of the middle, anterior, and part of the posterior cranial fossae.

2024年8月8日 · 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 anatomical course of the nerve, and the motor, sensory and parasympathetic functions of its terminal branches.

Cranial Nerve V1 – Ophthalmic Nerve (shown in blue) This is a purely sensory nerve that supplies the skin over the upper 1/3rd of the face and then in a narrow band down the center of the nose including the philtrum of the upper lip through its frontal and lacrimal branches.

The ophthalmic nerve (CN V1, Latin: nervus ophthalmicus) is the first branch or division of the trigeminal nerve (CN V). It is a sensory nerve transmitting sensory information to the central nervous system mostly from structures of the upper face region, including structures of the orbit , nasal cavity and paranasal sinuses , as well as from ...
