Summary Information: Cochlea

Cochlea: The cochlea is one component of the inner ear, the deepest cavity of the ear. The cochlea is shaped like a snail shell and is important to the sense of hearing. It contains three fluid-filled canals, one of which contains the hair cells, or sensory receptors for hearing in the organ of Corti.

Sound waves travel through the outer ear, into the middle ear where they cause vibration of the tympanic membrane. These vibrations are then transmitted through the auditory bones and into the fluid of the cochlea of the inner ear. In the cochlea, these sound vibrations or waves are picked up by the hair cells of the organ of Corti and converted into electrical impulses or signals and carried by the 8th cranial nerve to the brain.

Conditions that can afflict the cochlea include deterioration of the hair cells, aging, chronic exposure to loud noise, nerve deafness, and trauma.
