Arrange the following "sound processing events" in order, from start to finish. - Vibrations are conveyed to the endolymph inside the cochlea, causing the cochlear hair cells to bend - Sound waves cause the ear drum and middle ear bones to vibrate - Bending of the cochlear hair cells causes ion channels to open, which causes neurotransmitters to be released, which results in activation of the auditory nerve, which sends signals to the brain for processing. - Sound waves move down the auditory canal toward the ear drum

1) Sound waves move down the auditory canal toward the eardrum

2) Sound waves cause the eardrum and middle ear bones to vibrate

3) Vibrations are conveyed to the endolymph inside the cochlea, causing the cochlear hair cells to bend

4) Bending of the cochlear hair cells causes ion channels to open, which causes neurotransmitters to be released, which results in activation of the auditory nerve, which sends signals to the brain for processing
