Introduction:
The ear has three main parts: the outer ear, middle ear, and inner ear. The outer ear (the part you can see) opens into the ear canal. The eardrum separates the ear canal from the middle ear. The middle ear contains three small bones which help amplify and transfer sound to the inner ear. These three bones are called the malleus, the incus, and the stapes. The inner ear contains the cochlea which changes sound into neurological signals and the auditory nerve, which takes sound to the brain.
