Excerpt

The tympanic membrane (eardrum, myringa) is a thin, semitransparent, oval membrane, approximately 1 cm in diameter, that separates the external acoustic meatus from the tympanic cavity. It is positioned at the lateral end of the external acoustic meatus and it is tilted medially from posteriorly to anteriorly and superiorly to inferiorly. Therefore, the lateral surface of the tympanic membrane faces anteriorly and inferiorly.
