As the stapes moves, it pushes a structure called the oval window in and out. This action is passed onto the cochlea, which is a fluid-filled snail-like structure that contains the receptor organ for hearing. The cochlea contains the spiral organ of Corti, which is the receptor organ for hearing. It consists of tiny hair cells that translate the fluid vibration of sounds from its surrounding ducts into electrical impulses that are carried to the brain by sensory nerves.
Organ of Corti. (inside cochlea) organ located in the cochlea; contains receptors (hair cells) that receive vibrations and generate nerve impulses for hearing -------sense organ of hearing; runs along length of basilar membrane; consists of hair and support cells that react to the traveling wave. î î î.----- Sensorineural deafness: caused by the impairment if hair cells in the cochlea or damage of the cochlear branch of the vestibulocochlear nerve. -------Conduction deafness: caused by impairment of the outer and middle ear mechanisms for transmitting sounds to the cochlea.
