organ of Corti
The organ of Corti lies with the cochlea of the inner ear. In the organ of Corti, sound vibrations which pass along the cochlear duct are converted into nerve impulses. These impulses are transmitted along the cochlear nerve, or auditory nerve, to the brain, where they are interpreted as sound.
The organ of Corti lies on the basilar membrane close to the attachment to the osseus lamina. In this situation it extends throughout the whole of the 2 and three-quarter turns of the cochlear duct.
At the upper and free end of each hair a small number of acoustic hairs project into the cochlear duct. To each cell a minute fiber of the cochlear or acoustic nerve is attached.
