Only present in vertebrates, the ear is the organ of hearing. It is the management center sounds through the auditory apparatus whose functions extend from the capture process to that of deciphering.

The inner ear comprises the cochlea and the vestibule while posterior middle ear contains the eardrum, the hammer, anvil and stirrup, and the Eustachian mastoid trunk.
