Quizplus · Accepted Answer

The eardrum (tympanic membrane) receives sound waves and vibrates, causing the bones of the middle ear (malleus, incus, and stapes) to also vibrate, which in turn transmits the vibrations to the inner ear (cochlea). Therefore, the correct answer is B - eardrum. The vestibular sacs and semicircular canals are involved in balance and spatial orientation, not hearing.
