Ear Vocabulary

Back

The Outer Ear The diagram on the left shows the outer ear and the ear canal. The outer ear is the part that is on the outside of your body. The outer ear catches the sound waves and funnels them into the middle ear through the ear canal.

Back

The Middle Ear The diagram on the right shows the middle ear. It is located in the ear canal. It is also called the "Tympanic Cavity".This is also referred to as the ear drum. The vibrations hit the ear drum. When you have a middle ear infection there is fluid in the middle ear that stops the ear drum from moving.

Back

The Inner Ear The diagram to the left shows the inner ear. It is in the inner ear that the sound vibrations are changed into energy that our brains can understand. The fluid inside the cochlea (This is the section that looks like a sea shell.)vibrates a series of tiny hairs called cilia, which are attached to auditory nerves. The movement of these cilia stimulates the nerves, and they send signals to the brain, which, in turn, processes these signals into the sounds we hear.
