What part of the ear is responsible for hearing?

The inner ear consists of a spiral shaped structure known as the cochlea (means snail-shell). Within the cochlea sits the organ of hearing where we have thousands of tiny cells, known as hair cells. The hair cells are stimulated and send messages to the auditory nerve.

What are the middle ear bones quizlet?
