Cochlear Nerve

Sunday, June 19, 2011

The cochlear nerve is one of the two branches of the vestibulocochlear nerve (CN VIII), the other being the vestibular nerve. It transmits information about hearing. The cochlear nerve consists of axons that arise from the bipolar cells in the spiral ganglion, which is located in the cochlea, and have their receptors in the spiral organ of the cochlea. The cochlear nerve is a sensory nerve whose fibers extends to the brainstem, providing the temporal lobe of the brain with acoustic information from the invironment.
