Tympanic membrane
The tympanic membrane, also called an eardrum, is a thin membrane that separates the external ear from the middle ear in humans and other animals. It moves sound from the air to the ossicles inside the middle ear.[1] The malleus bone bridges the gap between the eardrum and the other ossicles.
