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:
“I would like to think that no one would die anymore
if we all believed in daisies
but the worms know better, don’t they?
They slide into the ear of a corpse
and listen to his great sigh.”
—Anne Sexton (1928–1974)
