The trigeminal nerve is the largest of the 12 cranial nerves. Its main function is transmitting sensory information to the skin, sinuses, and mucous membranes in the face. It also stimulates movement in the jaw muscles. This nerve controls muscles that turn the eyeball up, down, and medially, as well as controlling the iris, lens, and upper eyelid. The facial nerve is the seventh cranial nerve, or simply CN VII. It emerges from the pons of the brainstem, controls the muscles of facial expression, and functions in the conveyance of taste sensations from the anterior two-thirds of the tongue. There are a number of functions of the glossopharyngeal nerve: It receives general somatic sensory fibers (ventral trigeminothalamic tract) from the tonsils, the pharynx, the middle ear and the posterior 1/3 of the tongue. It receives special visceral sensory fibers (taste) from the posterior 1/3 of the tongue.

The only cranial nerves that transmit parasympathetic fibers are the oculomotor, facial, glossopharyngeal, and vagus nerves. 5 Special somatic afferent (SSA). These fibers carry special sensory input from the eye (retina), for vision, and from the ear (vestibular apparatus for equilibrium, and cochlea for hearing).

The trigeminal nerve is the largest of your cranial nerves and has both sensory and motor functions. The trigeminal nerve has three divisions, which are: Ophthalmic. The ophthalmic division sends sensory information from the upper part of your face, including your forehead, scalp, and upper eyelids.

Glossopharyngeal nerve is the ninth cranial nerve (CN IX). This nerve is accountable for controlling the muscles present in upper throat and oral cavity, and also part of the sense of taste and saliva production. The olfactory nerve is responsible for the sense of smell.

It is the longest nerve in the body, and technically it comes as a pair of two vagus nerves, one for the right side of the body and one for the left. It's called “vagus” because it wanders, like a vagrant, among the organs.

Masseter, temporalis, and lateral & medial pterygoid. Mastication muscles, tensor tympani, tensor veli palatini, mylohyoid, and anterior belly of digastric. The motor root of the trigeminal innervates which muscles? Name this muscle.

(Sensory) carry sensory information respon- sible for the sense of smell. The olfactory afferents synapse within the olfactory bulbs. (Sensory) carry visual information from special sensory receptors in the eyes. (Motor) are the primary source of in- nervation for four of the extrinsic eye muscles.

The Trigeminal Nerve—Cranial Nerve V The trigeminal nerve has three divisions and provides sensory innervation for the forehead and eye (ophthalmic V1), cheek (maxillary V2), and lower face and jaw (mandibular V3), as well as motor innervation for the muscles of mastication (Fig. 6-1).

Sensory nerves can be accessed by various routes, all of which leave minimal scarring. Peripheral nerves have potential for self-repair, but it is a slow process that may take 3-4 months or longer. Minor and superficial nerve injuries will often heal themselves.

Within a few hours, the trigeminal nerve is damaged, and pain signals are blocked. Most people experience significant pain relief with PGR, but pain may recur later. Many patients experience facial tingling or numbness. A balloon is sent down a hollow needle for inflation next to the nerve.

There are some instances when the nerve can be compressed by nearby blood vessels, aneurysms, or tumors. There are inflammatory causes of trigeminal neuralgia because of systemic diseases including multiple sclerosis, sarcoidosis, and Lyme disease.

The trigeminal nerve originates from three sensory nuclei (mesencephalic, principal sensory, spinal nuclei of trigeminal nerve) and one motor nucleus (motor nucleus of the trigeminal nerve) extending from the midbrain to the medulla.

Trigeminal neuralgia is severe facial pain due to malfunction of the 5th cranial nerve (trigeminal nerve). The cause is usually an abnormally positioned artery that compresses the trigeminal nerve. People have repeated short, lightning-like bursts of excruciating stabbing pain in the lower part of the face.
