The ophthalmic nerve is one of the branches of the trigeminal nerve, otherwise known as the fifth cranial nerve (CN V). The parotid gland is wrapped around the mandibular ramus and extends to a position anterior and inferior to the ear. The recurrent laryngeal nerve (RLN) is a branch of the vagus nerve (cranial nerve X) that supplies all the intrinsic muscles of the larynx, with the exception of the cricothyroid muscles.There are two recurrent laryngeal nerves, right and left. The long ciliary nerves, two or three in number, are given off from the nasociliary nerve as it crosses the optic nerve.The nasociliary nerve that the long ciliary nerves branch from is itself a branch of the ophthalmic branch (V 1) of the trigeminal nerve (CN V).. Meningeal branch, which serves the dura mater (a thick membrane that surrounds the brain and spinal cord) Buccal nerve, which transmits sensory information from the cheek and the back two molars; Auriculotemporal nerve, which provides sensory innervation to the side of your head; Lingual nerve, which provides sensation to the forward two-thirds of the tongue and To subserve this reflex protective function, mechanoreceptive nerves in the periodontal ligament sense tooth movement and project to the mesencephalic nucleus. Inferior nerve injury most commonly occurs during surgery including wisdom tooth, dental implant placement in Mandibular nerve. The nerve also acts as a conduit for sympathetic fibers that require access to the ciliary body, lacrimal glands, cornea, Function.
