Physiology of Hearing - Part 14
The auditory system is responsible for converting sound waves in the environment into electrical signals that the brain can receive and utilize as useful information about the sound characteristics of the external environment. Test your basic knowledge of auditory physiology by taking this simple quiz.
(1)   Another name for this structure is the secondary tympanic membrane.



(2)   When considering the conduction of sound waves to the inner ear, which of the following conduction pathways plays the greatest role in normal hearing?
