Auditory nerve
Auditory Nerve
The Auditory Nerve (pronunciation: /ˈɔːdɪtəri nɜːrv/), also known as the Cochlear Nerve, is one of the cranial nerves that is responsible for transmitting sound information from the inner ear to the brain.
Etymology
The term "Auditory Nerve" is derived from the Latin word "audire" which means "to hear" and the Latin word "nervus" which means "nerve".
Function
The Auditory Nerve is responsible for transmitting auditory information from the cochlea of the inner ear to the auditory cortex in the brain. This nerve is composed of two types of fibers: the cochlear nerve fibers and the vestibular nerve fibers. The cochlear nerve fibers are responsible for transmitting sound information, while the vestibular nerve fibers are responsible for transmitting information about balance and spatial orientation.
