The inner ear is the innermost part of the vertebrate ear. In mammals, it consists of the bony labyrinth, a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts:
- The cochlea, dedicated to hearing; converting sound pressure patterns from the outer ear into electrochemical impulses which are passed on to the brain via the auditory nerve.
- The vestibular system, dedicated to balance
The inner ear is found in all vertebrates, with substantial variations in form and function. The inner ear is innervated by the eighth cranial nerve in all vertebrates.

Famous quotes containing the word ear:
“All things are wearisome; more than one can express; the eye is not satisfied with seeing, or the ear filled with hearing. What has been is what will be, and what has been done is what will be done; there is nothing new under the sun.”
—Bible: Hebrew, Ecclesiastes 1:8-9.
