What is another name for trigeminal nerve?

The trigeminal nerve (the fifth cranial nerve, or simply CN V) is a nerve responsible for sensation in the face and motor functions such as biting and chewing; it is the most complex of the cranial nerves.

What is trigeminal nerve involvement?

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.

What is a trigeminal response?

Protective responses evoked by trigeminal stimulation include salivation, tearing, coughing, respiratory depression, and sneezing. Branches of the human trigeminal nerve innervating the face, the eye, and the nasal and oral cavities. Temperature and many chemical agents can stimulate chemosensitive channels directly.

What does the word trigeminal mean?

The trigeminal nerve is the fifth cranial nerve. The term “trigeminal” comes from the Latin “trigeminus” meaning “threefold,” referring to the three divisions (ophthalmic, maxillary and mandibular) of this nerve.

How do I calm my trigeminal nerve?

Many people find relief from trigeminal neuralgia pain by applying heat to the affected area. You can do this locally by pressing a hot water bottle or other hot compress to the painful spot. Heat a beanbag or warm a wet washcloth in the microwave for this purpose. You can also try taking a hot shower or bath.

What is Type 2 trigeminal neuralgia?

The atypical form of the disorder known as Trigeminal Neuralgia Type 2 (TN-2), is characterized by a constant aching, burning and stabbing pain of somewhat lower intensity when compared to Type 1. TN-2 is categorized to be more than 50% constant pain as opposed to sharp and fleeting pain.

What is the trigeminal chemosensory system?

The third of the major chemosensory systems, the trigeminal chemosensory system, consists of polymodal nociceptive neurons and their axons in the trigeminal nerve (cranial nerve V) and, to a lesser degree, nociceptive neurons whose axons run in the glossopharyngeal and vagus nerves (IX and X).

What are trigeminal sensations?

The trigeminal system is a chemical sense allowing for the perception of chemosensory information in our environment. We found that 4 main dimensions were linked to trigeminal perception: sensations of intensity, warmth, coldness, and pain.

What does Abducent mean?

drawing away, as by the action of a muscle; abducting.

What can irritate the trigeminal nerve?

Trigeminal neuralgia can also be caused by a tumor compressing the trigeminal nerve. Some people may experience trigeminal neuralgia due to a brain lesion or other abnormalities. In other cases, surgical injuries, stroke or facial trauma may be responsible for trigeminal neuralgia.

What is the best painkiller for neuralgia?

The anti-convulsant drug most commonly prescribed for trigeminal neuralgia is carbamazepine (Tegretol), which can provide at least partial pain relief for up to 80 to 90 percent of patients. Other anti-convulsants prescribed frequently for trigeminal neuralgia include: Phenytoin (Dilantin) Gabapentin (Neurontin)

What is the sensory portion of the trigeminal nerve?

The sensory portion of the trigeminal supplies touch–pain–temperature to the face. The nerve has three divisions: the ophthalmic, maxillary, and mandibular nerves (Figure 61.1).

What are the three divisions of the cranial nerve?

Sensory The three divisions of the nerve carry pain, temperature, and touch modalities from the skin of the face; the mucosa of sinuses, nose, and mouth; the teeth; and portions of the dura. They convey proprioceptive sensation from the teeth, hard palate, temporomandibular joint, and muscles of mastication.

Which is part of the cranial nerve carries motor impulses?

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. The mandibular division carries the motor portion. The motor portion conveys proprioceptive impulses from the temporomandibular joint.

What are the muscles of the motor division of the nerve?

The motor division of the nerve supplies the muscles of mastication: masseter, temporal, pterygoid, mylohyoid, and digastric. These muscles produce elevation, depression, protrusion, retraction, and the side-to-side movements of the mandible.
