cochlear nerve

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.

cochlear nerve

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

coch·le·ar nerve

(kok'lē-ăr nĕrv) [TA]
The part of the vestibulocochlear nerve peripheral to the cochlear root. It is composed of fibers with central nerve processes that arise from the bipolar neurons of the spiral ganglion and that have their peripheral processes on the four rows of neuroepithelial cells (hair cells) of the spiral organ.
Synonym(s): auditory nerve.

cochlear nerve

The branch of the 8th cranial nerve (ACOUSTIC NERVE) concerned with hearing.

coch·le·ar nerve

(kok'lē-ăr nĕrv) [TA]
Section of vestibulocochlear nerve [CN VIII] peripheral to the cochlear root.

* Majority of CH patients have severe to profound hearing loss where a CI would be a reasonable option, if they have a cochlear nerve. During surgery, facial nerve malposition is to be expected due to associated semicircular abnormalities (particularly lateral SCC).
The close relationship between the cochlear nerve and the greater potential for tumor extension under the transverse crest is considered responsible for the low rate of hearing preservation associated with schwannomas originating from the IVN.[sup][2],[15] Adhesion of the tumor to the adjacent structures, including the cochlear nerve, is considered to be another risk factor.[sup][16] Normal VEMP suggests that the nerve of tumor origin is the SVN, indicating that the IVN and the cochlear nerve are less affected.{Table 3}
