What is the tympanic membrane?

Explanation:
The tympanic membrane is the eardrum, a thin, flexible membrane at the end of the ear canal that vibrates when sound waves reach it. Those vibrations convert air-pressure fluctuations into mechanical motion, which then drives the middle-ear ossicles and ultimately helps transfer sound into the inner ear. It is not a bone in the middle ear, not a canal in the outer ear, and not a nerve carrying signals to the brain.
