Sound waves arrive at tympanic membrane

1

Movement of the tympanic membrane causes displacement of the auditory ossicles

2

Movement of the stapes at the oval window establishes pressure waves in the perilymph of the scala vestibuli

3

The pressure waves distort the basilar membrane on their way to the round window of the scala tympani

4

Vibration of the basilar membrane causes vibration of hair cells against the tectorial membrane

5

Information about the region and the intensity of stimulation is relayed to the CNS over the cochlear branch of cranial nerve VIII
