Ophthalmic nerve - wikipedia Ophthalmic nerve Ophthalmic nerve Oblique section through the cavernous sinus. Nerves of the orbit, and the ciliary ganglion. Side view. Details From trigeminal nerve To frontal nerve, lacrimal nerve, nasociliary nerve Identifiers Latin n. ophthalmicus MeSH A08. 800.800. 120.760. 650 TA A14. 2.01. 016 FMA 52621 Anatomical terms of neuroanatomy ( edit on Wikidata ) The ophthalmic nerve ( CN V : V ) is one of the three branches of the trigeminal nerve, the fifth cranial nerve. It carries sensory information from the face / scalp and sympathetic fibers for pupil dilation in the long ciliary branch of the nasociliary nerve. Contents 1 Structure 1.1 Branches 2 Function 3 Additional images 4 References 5 External links Structure The frontal branch passes through the orbit superiorly, then reenters the frontal bone briefly before exiting above the orbit through the superior orbital fissure and the supraorbital notch to provide sensory innervation for the skin of the forehead and scalp. The lacrimal nerve passes through the orbit superiorly to innervate the lacrimal gland. The nasociliary branch gives off several sensory branches to the orbit and then continues out through the anterior ethmoidal foramen, where it enters the nasal cavity and provides innervation for much of the anterior nasal mucosa. It also gives off a branch which exits through the nasal bones to form the external nasal branch. The ophthalmic nerve is joined by filaments from the cavernous plexus of the sympathetic, and communicates with the oculomotor, trochlear, and abducent nerves ; it gives off a recurrent ( meningeal ) filament which passes between the layers of the tentorium. Branches Nasociliary nerve sensory root of ciliary ganglion posterior ethmoidal nerve long ciliary nerve infratrochlear nerve anterior ethmoidal nerve lacrimal nerve frontal nerve supratrochlear nerve supraorbital nerve Function The ophthalmic nerve supplies branches to the cornea, ciliary body, and iris ; to the lacrimal gland and conjunctiva ; to the part of the mucous membrane of the nasal cavity ; and to the skin of the eyelids, eyebrow, forehead and nose. It is the smallest of the three divisions of the trigeminal, and arises from the upper part of the trigeminal ganglion as a short, flattened band, about 2.5 cm. long, which passes forward along the lateral wall of the cavernous sinus, below the oculomotor and trochlear nerves ; just before entering the orbit, through the superior orbital fissure, it divides into three branches, lacrimal, frontal, and nasociliary. It carries sensory branches from the eyes, conjunctiva, lacrimal gland, nasal cavity, frontal sinus, ethmoidal cells, falx cerebri, dura mater in the anterior cranial fossa, superior parts of the tentorium cerebelli, upper eyelid, dorsum of the nose, and anterior part of the scalp. Roughly speaking, the ophthalmic nerve supplies general somatic afferents to the upper face, skull, and eye : Face : Upper eyelid and associated conjunctiva. Eyebrow, forehead, scalp all the way to the lambdoid suture. Skull : Roof of orbit, frontal, ethmoid, and possibly sphenoid sinuses. Eye : The eye itself ( all the intraocular structures such as cornea ) and the lacrimal gland and sac. Compare this to the maxillary nerve, which supplies general somatic afferents to the mid-face and skull : Face : Lower eyelid and associated conjunctiva. Cheek, upper lip. Skull : Orbital floor, maxillary sinus, upper teeth, nasal cavity, and palate, cheekbone. Additional images Nerves of the orbit. Seen from above.
