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

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).

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.

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.

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 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.

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).

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

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.

The radial nerve is vulnerable as it passes through this space, for all of the reasons mentioned above.

There is also a small amount of cutaneous sensation carried by the nervus intermedius from the skin in and around the auricle (outer ear).

For example, fractures of the petrous temporal bone can selectively damage the nerve, as can aneurysms of the intracavernous carotid artery.

The syndrome may be due to anatomical variations in the muscle nerve relationship, or from overuse or strain.

Consanguinity, as commonly defined, does not depend on the amount of shared DNA within two people's genome.

Results may indicate lesion to the spinal cord nerve root, or intervertebral disc herniation pressing on the spinal nerve roots.

All of the oculomotor muscles innervated by the third nerve may be affected, but those that control pupil size are usually well preserved early on.

And these four types of information your optic nerve has about a million fibers in it, and 900,000 of those fibers send these four types of information.

The optic nerve is ensheathed in all three meningeal layers (dura, arachnoid, and pia mater) rather than the epineurium, perineurium, and endoneurium found in peripheral nerves.

The nerve's route would have been direct in the fish like ancestors of modern tetrapods, traveling from the brain, past the heart, to the gills (as it does in modern fish).

This creates a constraint on the evolution of the visual system such that the optic nerve is forced to exit the retina through a point called the optic disc.

And then to generate the display you're about to see, all I did was touch it once per second on its nerve ring with a sharp pick that's sort of like the sharp tooth of a fish.

The fibres from the retina run along the optic nerve to nine primary visual nuclei in the brain, from which a major relay inputs into the primary visual cortex.

However, at least 85 of patients have a relapsing form of the disease with repeated attacks of transverse myelitis and or optic neuritis.

The nervous system consists of a ventral nerve cord that runs the length of the body, with several ganglia and branches along the way reaching into the extremities of the appendages.

The following districts have been chosen in the Qaliobeya for the pilot period Benha, Qalioub, Shebin El Kanater and El Kanater El Khayreya districts.

Mass lesions that push the brainstem downward can damage the nerve by stretching it between the point where it emerges from the pons and the point where it hooks over the petrous temporal bone.

In general, neuroregeneration can occur in the peripheral nervous system but is much rarer and more difficult to assist in the central nervous system (brain or spinal cord).

The cathedral of Turku was the center of the cult of Saint Henry, and naturally the cultural center of the bishopric.

Fiber tracts of the mammalian central nervous system (as opposed to the peripheral nervous system) are incapable of regeneration, and, hence, optic nerve damage produces irreversible blindness.

In the experiment, the frog's leg was almost completely severed from its body, leaving only the sciatic nerve connected, and electric current was then applied from the body to the leg.
