Meniere's Disease Anatomy
To better understand Meniere's disease, it helps to understand the anatomy of the inner ear.
The inner ear contains the semi-circular canals, which also contain fluid and hair cells. The hair cells in the semi-circular canals sense the position of the body and send this information to the brain. This structure allows the body to maintain balance and equilibrium.
- Pinna: the cartilage and skin of the external ear
- Ear canal: passageway that leads to the eardrum
- Tympanic membrane: the eardrum
- Ossicles: three tiny bones that vibrate when sound waves strike the eardrum
- Inner ear, or labyrinth: includes the cochlea and semi-circular canals
- Cochlea: contains fluid and hair cells
- Semi-circular canals: contains fluid and hair cells
