The main function of the tympanic membrane is to transmit sound from the air to the ossicles inside the middle ear and also to the oval window in the fluid-filled cochlea. A Frog's Tympanum. The tympanic Membrane's main function is to assist in human hearing. Carlos Mota, Serena Danti, in Comprehensive Biotechnology (Third Edition), 2019. It does not process sound waves; it simply transmits them to the inner parts of the amphibian's ear, which is protected from the entry of water and other foreign objects. The tympanic membrane is comprised of three layers of tissue: the outer cutaneous layer, the fibrous middle layer, and a layer of mucous membrane on its innermost surface. The tympanic membrane (eardrum) is an oval, semi-transparent structure situated between the external auditory meatus and the tympanic cavity of the middle ear .

Describe the interprofessional team strategies for improving care coordination and communication to advance tympanic membrane perforation and improve outcomes. Tympanic Membrane: eardrum, located behind eyes. Just behind the eyes on the frog's head is a circular structure called the tympanic membrane. The membrane vibrates with the force of a sound wave strike and transmits the vibrations further into the bones of the middle ear. The tympanic membrane is a thin membrane behind the frog's eyes that separates the outside from the frog's inner ear. The size of the tympanum and the distance between them are relative to the frequency . frog can breath through these with it's mouth closed, can be opened or closed with sphincter muscles: external nares: external nostril opening: eustachian tubes: opening to the typanum (eardrum) typanum (tympanic membrane or eardrum) serves to equalize pressure within: vocal sacs: only in males, can be inflated with air to make the mating call .
