Question

Quizplus · Accepted Answer

The stirrup (or stapes bone) of the ear transmits vibrations from the eardrum to the oval window, which is a membrane that separates the middle ear from the inner ear. When the stirrup vibrates against the oval window, it creates pressure waves within the fluid-filled cochlea of the inner ear, which causes the hair cells on the basilar membrane to move and generate signals to the brain that are interpreted as sound.
