Cochlear nerve

Index Cochlear nerve

The cochlear nerve (also auditory or acoustic neuron) is one of two parts of the vestibulocochlear nerve, a cranial nerve present in amniotes, the other part being the vestibular nerve. [1]

Action potential

In physiology, an action potential occurs when the membrane potential of a specific axon location rapidly rises and falls: this depolarisation then causes adjacent locations to similarly depolarise.

Amniote

Amniotes (from Greek ἀμνίον amnion, "membrane surrounding the fetus", earlier "bowl in which the blood of sacrificed animals was caught", from ἀμνός amnos, "lamb") are a clade of tetrapod vertebrates comprising the reptiles, birds, and mammals.

Axon

An axon (from Greek ἄξων áxōn, axis) or nerve fiber, is a long, slender projection of a nerve cell, or neuron, that typically conducts electrical impulses known as action potentials, away from the nerve cell body.

Bipolar neuron

A bipolar neuron or bipolar cell, is a type of neuron which has two extensions.

Brain

The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals.

Cochlea

The cochlea is the part of the inner ear involved in hearing.

Cochlear implant

A cochlear implant (CI) is a surgically implanted electronic device that provides a sense of sound to a person with severe to profound sensorineural hearing loss in both ears.

Cochlear nerve

The cochlear nerve (also auditory or acoustic neuron) is one of two parts of the vestibulocochlear nerve, a cranial nerve present in amniotes, the other part being the vestibular nerve.

Cochlear nucleus

The cochlear nuclear (CN) complex comprises two cranial nerve nuclei in the human brainstem, the ventral cochlear nucleus (VCN) and the dorsal cochlear nucleus (DCN).

Cranial nerves

Cranial nerves are the nerves that emerge directly from the brain (including the brainstem), in contrast to spinal nerves (which emerge from segments of the spinal cord).

Dendrite

Dendrites (from Greek δένδρον déndron, "tree"), also dendrons, are branched protoplasmic extensions of a nerve cell that propagate the electrochemical stimulation received from other neural cells to the cell body, or soma, of the neuron from which the dendrites project.

Glutamic acid

Glutamic acid (symbol Glu or E) is an α-amino acid with formula.

Inner ear

The inner ear (internal ear, auris interna) is the innermost part of the vertebrate ear.

Internal auditory meatus

The internal auditory meatus (also meatus acusticus internus, internal acoustic meatus, internal auditory canal, or internal acoustic canal) is a canal within the petrous part of the temporal bone of the skull between the posterior cranial fossa and the inner ear.

Myelin

Myelin is a lipid-rich substance that surrounds the axon of some nerve cells, forming an electrically insulating layer.

Organ of Corti

The organ of Corti, or spiral organ, is the receptor organ for hearing and is located in the mammalian cochlea.

Ribbon synapse

The ribbon synapse is a type of neuronal synapse characterized by the presence of an electron-dense structure, the synaptic ribbon, that holds vesicles close to the active zone.

Semicircular canals

The semicircular canals or semicircular ducts are three semicircular, interconnected tubes located in the innermost part of each ear, the inner ear.

Spiral ganglion

The spiral (cochlear) ganglion is the group of nerve cells that serve the sense of hearing by sending a representation of sound from the cochlea to the brain.

Tonotopy

In physiology, tonotopy (from Greek tono.

Unipolar neuron

A unipolar neuron is a type of neuron in which only one protoplasmic process (neurite) extends from the cell body.

Vestibular nerve

The vestibular nerve is one of the two branches of the vestibulocochlear nerve (the cochlear nerve being the other).

Vestibulocochlear nerve

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.
