Place the steps in the production of an auditory sensation in order from start to finish. information concerning the frequency and intensity of stimulation is relayed to the cns over the cochlear branch of n viii. the pressure waves distort the basilar membrane on their way to the round window of the tympanic duct. sound waves arrive at the tympanic membrane. movement of the stapes at the oval window establishes pressure waves in the perilymph of the vestibular duct. vibration of the basilar membrane causes vibration of hair cells against the tectorial membrane, resulting in hair cell stimulation and neurotransmitter release. movement of the tympanic membrane causes displacement of the auditory ossicles.
