tympanic membrane

tympanic membrane
= eardrum
the membrane at the inner end of the external auditory meatus, separating the outer and middle ears. It is formed from the outer wall of the lining of the tympanic cavity and the skin that lines the external auditory meatus. When sound waves reach the ear the tympanum vibrates, transmitting these vibrations to the malleus – one of the auditory ossicles in the middle ear – to which it is attached.
