D)basilar membrane.

Question

Quizplus · Accepted Answer

The vibrations of sound waves cause the eardrum to vibrate, which in turn causes the bones of the middle ear (the malleus, incus, and stapes) to vibrate. These vibrations transmit the sound waves to the inner ear where they are processed by the cochlea. Therefore, the correct answer is B, the eardrum. The sacule is part of the vestibular system and the basilar membrane is within the cochlea, but neither directly cause vibrations of the middle ear bones.
