Inner Ear

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:

    That strain again, it had a dying fall;
    O, it came o’er my ear like the sweet sound
    That breathes upon a bank of violets,
    Stealing and giving odor. Enough, no more,
    ‘Tis not so sweet now as it was before.
    William Shakespeare (1564–1616)
