Eardrum - definition

aka tympanic membrane. The tympanic membrane is a membrane that separates the outer from middle ear. Sound waves hit the tympanic membrane, causing it to vibrate. The vibration is then transferred to the ossicles, which transmit the vibrations to the inner ear where the receptors for hearing are located.

BIZARRE

This book shows a whole other side of how brains work by examining the most unusual behavior to emerge from the human brain. In it, you'll meet a woman who is afraid to take a shower because she fears her body will slip down the drain, a man who is convinced he is a cat, a woman who compulsively snacks on cigarette ashes, and many other unusual cases. As uncommon as they are, each of these cases has something important to teach us about everyday brain function.

Through case studies of both exceptional people as well as those with disorders, Bizarre takes us on a fascinating journey in which we learn more about what is going on in our skull. - William J. Ray, PhD, Emeritus Professor of Psychology, The Pennsylvania State University, author, Abnormal Psychology
