Assertion: Hair cells on the basilar membrane (organ of Corti) are responsible for hearing. Reason: Pressure waves, which begin at the oval windows, cause the basilar membrane to vibrate so that the cilia of the hair cells touch the tectorial membrane. This causes the hair cells to initiate nerve impulses, which are carried by the auditory nerve to the brain.

Hair cells on the basilar membrane is responsible for hearing. In the cochlear duct of the internal ear, the basilar papilla forms a basilar membrane with hair cells constituting an organ of Corti, the fibres are embeded in a tectorial membrane lying above the organ of Corti which is sensitive to vibrations of high frequency.
