Encyclopedia > Tympanic membrane

The tympanum or tympanic membrane, colloquially known as eardrum, is a thin membrane that separates the outer ear from the middle ear. Its function is to transmit sound from the air to the ossicles inside the middle ear. The malleus bone connects the eardrum to the other ossicles.

The tympanum or tympanic membrane, colloquially known as the eardrum, is a thin membrane that separates the outer ear from the middle ear.
The tympanic membrane forms from the joining of the expanding first pharyngeal pouch and groove.
As a result, the tympanic membrane is one of very few adult structures that is derived from all three germ layers.
