The stapes (the smallest bone in the human body) sits against the oval window, which is a membrane-covered opening between the middle ear and inner ear. This movement of the stapes against the oval window causes fluid inside the cochlea (in the inner ear) to move, which leads to the sensation of hearing. The tympanic membrane (eardrum) is located at the entrance to the middle ear, and it vibrates in response to sound waves entering the ear, ultimately transmitting these vibrations to the three tiny bones of the middle ear - the malleus, incus, and stapes - which help amplify the vibrations as they are transmitted to the inner ear. The incus is located between the malleus and stapes.
