Cochlear nerve
Cochlear Nerve
The Cochlear Nerve (pronunciation: /ˈkɒklɪər ˈnɜːrv/), also known as the auditory nerve, is one of the two parts of the vestibulocochlear nerve, the other being the vestibular nerve. The term "cochlear" is derived from the Latin word "cochlea" meaning "snail," referring to the spiral shape of the inner ear.
Function
The cochlear nerve carries auditory sensory information from the cochlea of the inner ear directly to the brain. The primary function of the cochlear nerve is the transmission of signals from the inner ear to the brain, which interprets these signals as sound.
Anatomy
The cochlear nerve originates from the spiral ganglion cells in the cochlea. It travels through the internal auditory canal to the brainstem where it synapses in the cochlear nucleus, a collection of brainstem nuclei.
