Tympanum [TIM-puh-nuh m](noun): The ear opening in many amphibians, reptiles and insects (in amphibians, normally covered by a circular membrane).. that ends with a four pointed tip called an ovipositor. Frog's skin is always slimy because it has mucus on it that helps keep the skin moist. A frog's eardrum is called a tympanic membrane, or tympanum. 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's main function is to assist in human hearing. 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. Stomach 6. Frogs do not have external ears like us. The tympanic membrane acts as an eardrum.well it acts like a eardrum and it helps it hear thingsThe tympanic membrane acts as.
