cochlea
Has tiny hairs that turn vibrations into nerve impulses
The cochlea is a spiral-shaped, fluid-filled structure located in the inner ear. It is responsible for transforming sound vibrations into electrical signals that can be interpreted by the brain as meaningful sounds. The cochlea contains tiny hair cells along its length that are responsible for transducing the movement of the fluid within the cochlea into electrical signals that are sent to the brain. These hair cells are extremely sensitive and can be damaged or destroyed by exposure to loud noise, certain medications, or aging. Damage to the hair cells in the cochlea can lead to hearing loss or even complete deafness. Treatment for hearing loss caused by cochlear damage may include hearing aids, cochlear implants, or other assistive devices.
