Question

when vibration reach the inner ear they are caught by a fluid and passed on to the hair which are stimulated to produce______
​

Answer 1

The hair cells located in the organ of Corti transduce mechanical sound vibrations into nerve impulses. They are stimulated when the basilar membrane, on which the organ of Corti rests, vibrates

Answer 2

The mechanical vibrations of the stapes footplate at the oval window creates pressure waves in the perilymph of the scala vestibuli of the cochlea. These waves move around the tip of the cochlea through the helicotrema into the scala tympani and dissipate as they hit the round window. The wave motion is transmitted to the endolymph inside the cochlear duct. As a result the basilar membrane vibrates, which causes the organ of Corti to move against the tectoral membrane, stimulating generation of nerve impulses to the brain.
