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 tympanic membrane, or tympanum, is the circular patch of skin directly behind its eye that we commonly call its eardrum. The membrane vibrates with the force of the hitting sound waves and transmits the vibrations further, to the bones of the middle ear. Frogs (and toads) need to hear well both in the air and in the water. Frog's skin is always slimy because it has mucus on it that helps keep the skin moist. tympanic membrane, also called eardrum, thin layer of tissue in the human ear that receives sound vibrations from the outer air and transmits them to the auditory ossicles, which are tiny bones in the tympanic (middle-ear) cavity.

In the middle of the head, just in front of the eyes, there is a light coloured patch-the brow spot which represents the vestigial pineal eye. The tympanic membrane is divided into two main parts : Pars tensa - forms most of the tympanic membrane. The tympanic membrane is a thin membrane behind the frog's eyes that separates the outside from the frog's inner ear. The chemical permeation enhancers incorporated in the delivery system increased the permeability of the tympanic membrane to the anesthetics considerably. Nictitating Membrane: clear eyelid, protects the eye. What is the tympanic membrane commonly known as?
