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?
(3) The famous American inventor, Thomas Edison, suffered from impaired hearing during most of his adult life. He loved listening to the piano, however, and the only way he could enjoy piano music was to bite into his piano while it was being played by another person. Which pathway of sound conduction was Edison taking advantage of in order to enjoy piano music?
(4) For high-pitched (i.e., high frequency) sounds, the displacement of the cochlear basilar membrane is maximal near the __________ of the cochlea.
(5) For low-pitched (i.e., low frequency) sounds, the displacement of the cochlear basilar membrane is maximal near the __________ of the cochlea.
