co·chle·ar nerve

[TA]
the part of the vestibulocochlear nerve [CN VIII] peripheral to the cochlear root; composed of the central nerve processes of the bipolar neurons of the spiral ganglion, which have their peripheral processes on the four rows of neuroepithelial cells (hair cells) of the spiral organ.
See also: cochlear root of cranial nerve VIII.

cochlear nerve

n.
One of two divisions of the vestibulocochlear nerve that facilitate hearing by conducting stimuli to the brain.

cochlear nerve

Etymology: L, cochlea, snail shell, nervus, nerve
one of the main divisions of the eighth cranial nerve, with fibers that arise in spiral ganglion cells of the spiral organ and terminate in the dorsal and ventral cochlear nuclei of the brainstem. See also vestibulocochlear nerve.
