Quizplus · Accepted Answer

The stapes bone, the last bone in the chain of ossicles in the middle ear, is directly connected to the oval window. When the stapes vibrates in response to sound waves, it causes the oval window to vibrate, which in turn sets the fluid inside the cochlea in motion, leading to the sensation of hearing. Therefore, vibrations in the stapes directly induce vibrations in the oval window, not in the tympanic membrane or the incus. While the round window is also connected to the cochlea, it is not directly involved in transmitting vibrations from the middle ear to the inner ear.
