Quizplus · Accepted Answer

The external auditory canal and middle ear cavity are separated by the tympanic membrane, commonly known as the eardrum. The stapes is one of the three small bones in the middle ear that transmit sound vibrations from the eardrum to the inner ear. The vestibule is part of the inner ear and contains the utricle and saccule, which help with balance and spatial orientation. The oval window is another part of the middle ear and is connected to the inner ear.
