The cochlear nerve or auditory or acoustic nerve is a nerve in the head that carries signals from the cochlea of the inner ear to the brain. It has been empirically recognized that the cochlear nerve is highly vulnerable to traumatic stress. Hearing loss can result from a lesion anywhere within the auditory system and the problems of differentiating cochlear dysfunction from nerve lesions have received major emphasis during the past several years.

Can conduction deafness result from a lesion on the cochlear nerve?
Yes the result from a lesion on the cochlear nerve is sensorineural deafness. The result from the fusion of the ossicles is conduction deafness.
What is another name for the auditory nerve?
VESTIBULO-COCHLEAR nerve which is 8th cranial nerve.
What causes Compressive optic neuropathy?
This is the result of a tumor or other lesion putting pressure on the optic nerve
Where is the vestibulocochlear nerve situated?
extends from the inner ear to the brain and is made up of a vestibular branch, often called the vestibular nerve, and a cochlear branch, called the cochlear nerve. The vestibular and cochlear nerves lie next to one another
The axons of the cochlear nerve first synapse on the cochlear nucleus which is located within the?
medulla oblongata
Carries auditory information to the brain?
cochlear nerve
What nerves combine to form the auditory nerve?
Vestibular nerve and cochlear nerve combines to form the vestibulocochlear nerve or the auditory nerve.
What nerves carries messages of sound to the brain?
the cochlear nerve
What is the function of cochlea nerve?
The cochlear nerve (also auditory or acoustic nerve) is a nerve in the head that carries signals from the cochlea of the inner ear to the brain. It is part of the vestibulocochlear nerve, the 8th cranial nerve which is found in higher vertebrates; the other portion of the 8th cranial nerve is the vestibular nerve which carries spatial orientation information from the semicircular canals. The cochlear nerve is a sensory nerve, one which conducts to the brain information about the environment, in this case acoustic energy impinging on the tympanic membrane. The cochlear nerve arises from within the cochlea and extends to the brainstem, where its fibers make contact with the cochlear nucleus, the next stage of neural processing in the auditory system.
Does the cochlear duct relays vibrations to the auditory nerve fibers?
no
Nerve hearing impairment can be best treated with what?
cochlear implants
Impulses are transmitted from the inner ear to the brainstem by way of the?
cochlear nerve
