The trigeminal nerve carries general somatic afferent fibers (GSA), which innervate the skin of the face via ophthalmic (V1), maxillary (V2) and mandibular (V3) divisions. The trigeminal nerve also carries special visceral efferent (SVE) axons, which innervate the muscles of mastication via the mandibular (V3) division.
The ophthalmic nerve (CN V 1) 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.
Trigeminal neuralgia. This disorder is characterized by episodes of severe facial pain along the trigeminal nerve divisions. The trigeminal nerve is a paired cranial nerve that has three major branches: the ophthalmic nerve (V 1), the maxillary nerve (V 2), and the mandibular nerve (V 3). One, two, or all three branches of the nerve may be ...
The long ciliary nerves are 2-3 [1] nerves that arise from the nasociliary nerve (itself a branch of the ophthalmic branch (CN V 1) of the trigeminal nerve (CN V)).They enter the eyeball to provide sensory innervation to parts of the eye, and sympathetic visceral motor innervation to the dilator pupillae muscle.
The trigeminal nerve goes from the brain to the face and branches out into three locations (hence the tri in the name). One branch runs along the scalp, providing sensation there. The second ...
The frontal nerve is a branch of the ophthalmic nerve (V 1), itself a branch of the trigeminal nerve (CN V). [1] The frontal nerve branches immediately before entering the superior orbital fissure. In then travels superolateral to the annulus of Zinn between the lacrimal nerve and inferior ophthalmic vein.
The nasociliary nerve is a branch of the ophthalmic nerve (CN V 1) (which is in turn a branch of the trigeminal nerve (CN V)). It is intermediate in size between the other two branches of the ophthalmic nerve, the frontal nerve and lacrimal nerve. [1]
the nasociliary branch of the ophthalmic branch (V 1) of the trigeminal nerve (CN V) sensing the stimulus on the cornea only (afferent fiber). the temporal and zygomatic branches of the facial nerve (CN VII) initiating the motor response (efferent fiber). the center is located in the pons of the brainstem.
