Quizplus · Accepted Answer

The correct sequence of steps in the production of an auditory sensation is:
1. Sound waves arrive at the tympanic membrane (4)
2. Movement of the tympanic membrane causes displacement of the auditory ossicles (6)
3. Movement of the stapes at the oval window establishes pressure waves in the perilymph of the vestibular duct (3)
4. The pressure waves distort the basilar membrane on their way to the round window (1)
5. Vibration of the basilar membrane causes vibration of hair cells against the tectorial membrane (2)
6. Information concerning the frequency and intensity of stimulation is relayed to the CNS (5)
Therefore, the correct order is 4-6-3-1-2-5, which is option B.
