The eardrum moves synchronously in response to variations in air.

Tympanic membrane anatomy. Its function is to transmit sound from the air to the ossicles inside the middle ear and then to the oval window in the fluid filled cochlea. The tympanic membrane also called the eardrum or just the drum is a stiff but flexible translucent diaphragmlike structure. Membrana tympanica is a cone shaped thin membrane at the end of the external acoustic meatus which separates the external ear from the middle ear.

The tympanic membrane also known as eardrum myringa membranous wall of tympanic cavity latin. It also serves as the lateral wall of the tympanic cavity separating it from the external auditory canal. Lettering scheme taken from jerger j clinical experience with impedance audiometry.

The membrane is held in place by a thick ring of cartilage a tough but flexible kind of tissue. The tympanic membrane is comprised of three layers of tissue. The tympanic membranes function is to assist in human hearing.

In the anatomy of humans and various other tetrapods the eardrum also called the tympanic membrane or myringa is a thin cone shaped membrane that separates the external ear from the middle ear.
