Parts of the Ear

Mom holding babyThe ear has three parts: the outer ear, the middle ear, and the inner ear. A hearing loss can happen when any of these parts are not working in the usual way.


Outer Ear

The outer ear is made up of three parts; the part we see on the sides of our heads (pinna), the ear canal, and the eardrum (tympanic membrane).

Middle Ear

The middle ear is made up of the eardrum and three small bones (ossicles) that send the movement of the eardrum to the inner ear.

Inner Ear

The inner ear is made up of the snail shaped organ for hearing (cochlea) and the nerves that go to the brain.

Pinna: (Auricle) This is the part of the ear that we see on each side of our heads. It is a part of the outer ear. The pinna collects sound and sends it down the ear canal to the rest of the ear.
Outer Ear: The outer ear is made up of the parts we see (pinna), the ear canal, and eardrum (tympanic membrane).
Tympanic membrane: The eardrum.
Ossicles: The chain of three tiny bones in the middle ear (malleus, incus, stapes).
Inner Ear: The inner ear is made up of the snail shaped organ for hearing (called the cochlea) and the nerves that go to the brain.
Cochlea: The cochlea is in the inner ear. It's a snail-shaped tube that is filled with fluid and has tiny hair cells. Sound that comes into the cochlea moves the hair cells back and forth. This turns sounds into electrical signals that are sent to the brain through the auditory (hearing) nerve.
Middle Ear: The inner ear is made up of the snail shaped organ for hearing (called the cochlea) and the nerves that go to the brain.
