Question

Quizplus · Accepted Answer

The oval window is the structure in the middle ear that vibrates in response to the vibrations of the ossicles (the bones in the middle ear). This vibration is then transmitted into the cochlea of the inner ear, initiating the process of hearing. The tympanic membrane (or ear drum) is what initially vibrates in response to sound waves, not what the bones in the middle ear vibrate against. The auditory nerve carries the electrical signals from the cochlea to the brain but is not directly vibrated by the bones.
