trigeminal

The trigeminal nerve, which is the part of the nervous system that sends touch, pain, and temperature feelings from your face to your brain, interprets it.

As you repeat this process, you can withstand stronger and stronger burns because the nerve endings on your tongue that communicate with the trigeminal nerve become desensitized, inhibiting transmission of pain signals.

“We know pain is caused by … abnormal activity in multiple parts of the brain, including the trigeminal nerve, trigeminal nucleus caudalis in the brain stem, and the pain networks,” Starling says.

Migraines involve a series of events in the brain that is still not fully understood, but involves activation of the trigeminal nerve and release of a peptide called CGRP, causing pain in the head, face and jaw, plus other symptoms.

Anteriorly it is pierced by a pair of small foramina through which the ophthalmic branches of the trigeminal nerve pass out.

Between the trigeminal and optic foramina are the very small foramina for the sixth nerves (fig. 25, B, VI).

These perforate the palatine and transmit branches of the trigeminal nerve and certain blood-vessels.

The epimeral purely sensory nerves to the somatic surface, equivalent in the vertebrate to the ascending root of the trigeminal.

All the muscles belonging to this oral chamber are of the visceral type, and are innervated by the trigeminal nerve.
