Our ear and hearing is made up of many parts. Hearing loss can happen when any part of the ear or auditory (hearing) system is not working in the usual way.
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).
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.
The inner ear is made up of the snail shaped organ for hearing (cochlea), the semicircular canals that help with balance, and the nerves that go to the brain.
The ear (auditory) Nerve
The hearing (auditory) System pathway in 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.
