What Is the Cochlear Nerve?

The cochlear nerve refers to the branch of the auditory nerve. The inherent part of hearing originates from the spiral ganglia, and finally extends to the cochlear nucleus at the junction of the dorsal side of the brain and the dorsal side of the pontine. In the ganglia, bipolar nerve cells conduct the auditory information received by the Curtis' organ to the auditory cortex. The peripheral processes (ie, the dendrites of the cells) emit nerve fibers in a radial pattern and are distributed in the spiral. In the spiral organ, nerve fibers are mainly divided into two groups, one reaches the inner hair cells, and the other reaches the outer hair cells. The central process of a bipolar nerve cell is an axon. After it is emitted from the ganglion cells, it passes through the snail axis through the spiral hole at the bottom of the inner ear canal to the inner ear canal and merges with the vestibular nerve fibers into the auditory nerve. ^[1]
