Which structure within the inner ear converts sound vibrations into nerve signals that the brain can interpret?

Explanation

The cochlea, a small, fluid-filled, spiral-shaped structure in the inner ear, contains specialized hair cells that convert incoming sound vibrations into electrical nerve signals sent to the brain for interpretation as sound. Sound waves first cause the eardrum to vibrate, and these vibrations are then transmitted through the tiny bones of the middle ear before reaching the cochlea. Damage to the delicate hair cells within the cochlea, often from prolonged exposure to loud noise, is a common cause of hearing loss.
