Eardrum (tympanic Membrane)
The Eardrum, or tympanic membrane, is a thin flap of skin at the end of the ear canal. When sound waves hit the eardrum it creates vibrations that travel through the middle ear to the inner ear. The inner ear then sends a message to our brain about what we are hearing. The eardrum also protects the inside of the ear from water, bacteria, and other foreign objects.
