The vestibulocochlear nerve (auditory vestibular nerve), known as the eighth cranial nerve, transmits sound and equilibrium (balance) information from the inner ear to the brain.

Then, ion pumps pump the sodium back back out of the nerve, and the potassium back into the nerve, restoring the nerve to its normal resting state.

The facial nerve is the seventh cranial nerve, or simply cranial nerve VII.

Some people!

When the electrical impulse reaches the end of the nerve, small vesicles, or packets, containing chemical neurotransmitters, are released by the nerve and rapidly interact with the nerve's target.

This is called the nerve's resting potential.

The tumor cells always stay on the outside of the nerve, but the tumor itself may either push the nerve aside and or up against a bony structure (thereby possibly causing damage).

It can lead to problems with auditory memory and auditory sequencing.

The end of the nerve, the end of the axon, communicates with the nerve's target.

And during this overshoot, the nerve is resistant to further depolarization it is refractory, which prevents the nerve electrical impulse from traveling backwards.

A twitch in a thumb, a nerve or a muscle.

It is 20 times higher than in the fluid outside the nerve while that outside fluid has 10 times more sodium than the inside of a nerve.

The inside of a nerve is a fluid that is very rich in the ion potassium.

I haven't the nerve and strength for the sort of thing you want.

So just the same way that we were able to jump over the damaged circuitry in the retina to get to the retina's output cells, we can jump over the damaged circuitry in the cochlea to get the auditory nerve, or jump over damaged areas in the cortex, in the motor cortex, to bridge the gap produced by a stroke.

The temporal lobe is involved in primary auditory perception, such as hearing, and holds the primary auditory cortex.

Two eyes at the bottom, optic nerve flowing out from the back.

Or the nerve's target may be another organ, such as a muscle.

I learned they are the sinew which hold the force together.

The trochlear nerve (the fourth cranial nerve) is a motor nerve (a somatic efferent nerve) that innervates a single muscle the superior oblique muscle of the eye.

The International Foundation for Optic Nerve Diseases (IFOND) sponsors research and information on a variety of optic nerve disorders and may provide general direction.

Keep your nerve, said the Voice. I'm an Invisible Man.

As a part of the vagus nerve, it comes from the brain, passes through the neck down to heart, rounds the dorsal aorta and returns up to the larynx, again through the neck.

The actual nerve supplying the arm was severed, was cut, by say, a motorcycle accident.

This process is called synaptic transmission, because the connection between the nerve and the next object in the chain is called a synapse.

So we are really duplicating the kind of signals that you have on the optic nerve.

His condition was very rare because auditory agnosia for nonverbal sounds is usually associated with the right side of the brain.

The sixth nerve, the abducens nerve, which innervates the lateral rectus muscle of the eye (moves the eye laterally), is also commonly affected but fourth nerve, the trochlear nerve, (innervates the superior oblique muscle, which moves the eye downward) involvement is unusual.

They recognized these symptoms were the result of inflammation of the optic nerve and spinal cord, respectively.

One nerve's receptor might be a thermal receptor, designed only to respond to a rapid increase in temperature.

These pores are specialized protein channels that are designed to let sodium rush into the nerve.

But the same neuron, in some cases, will fire when I simply watch another person being touched.

And if I tap the nerve ending on a World War II vet, he'll still feel his missing hand.

Now, I'll prime your auditory part of your brain to tell you what you're supposed to hear, and then hear it again.

Work could be extended to other sectors, including the audiovisual sector, tourism, biotechnology, environmental goods and services, and pharmaceuticals.

Smile surgery or smile reconstruction is a surgical procedure that may restore the smile for people with facial nerve paralysis.

The nerve impulse starts with a receptor, a specialized part of each nerve, where the electrical impulse begins.

Meanwhile, potassium ion channels open, potassium rushes out of the nerve, and the membrane voltage returns to normal.

By far, the three most common injuries to the optic nerve are from glaucoma, optic neuritis (especially in those younger than 50 years of age), and anterior ischemic optic neuropathy (usually in those older than 50).

In that aspect, consanguinity is the quality of being descended from the same ancestor as another person.

In pathology, perineural invasion, abbreviated PNI, refers to cancer spreading to the space surrounding a nerve.
