Question

Quizplus · Accepted Answer

The basilar membrane is responsible for detecting vibrations in the cochlea. When sound waves enter the ear, they travel down the ear canal and cause the eardrum to vibrate. The vibrations are then transmitted to the three tiny bones in the middle ear that in turn transmit the vibrations to the cochlea. The basilar membrane, which is located inside the cochlea, is made up of thousands of hair cells that detect the vibrations and send signals to the brain, allowing us to hear sounds.
