Quizplus · Accepted Answer

The boundary between the middle ear and inner ear is the oval window, which is a flexible membrane separating the middle and inner ear. When sound waves vibrate the eardrum, the motion is transmitted through three tiny bones (the ossicles) in the middle ear, which in turn push and pull on the oval window. This movement creates pressure waves in the fluid of the inner ear, which stimulates the sensory hair cells and enables us to perceive sound.
