Quizplus · Accepted Answer

The eardrum, also called the tympanic membrane, is located deep in the ear canal and vibrates in response to sound waves. The vibration of the eardrum is the first step in the process of transmitting sound waves through the ear. The pinna, stapes, and malleus are also important parts of the ear, but they do not vibrate in response to sound waves. The pinna is the visible outer part of the ear that helps to collect sound waves, while the stapes and malleus are bones in the middle ear that transmit and amplify sound waves.
