Vibrate Cochlea Diagram. The sound waves on striking the eardruip make it vibrate exactly the same way as the given sound emitting object. The brain interprets the impulses as sound and can tell which.
It houses the organ of corti which has sensory hair cells called stereocilia. These signals travel to the brain along the cochlear nerve also known as the auditory nerve. Resting on the basilar membrane is the spiral organ or organ of corti.
Sound causes the eardrum and its tiny attached bones in the middle portion of the ear to vibrate and the vibrations are conducted to the nearby cochlea.
These little bones transfer the sound to the cochlea which is full of fluid. When a vibration is carried through the cochlea the fluid within the three compartments causes the basilar membrane to respond in a wave like manner. They then convert the vibrations into nerve impulses that are sent to our brains for interpretation. Total internal reflection b.
