Which is the correct order of events of sound transmission through the ear?
1. sound waves strike the eardrum
2. the ear ossicles vibrate
3. hair cells of the organ of corti vibrate
4. the perilymph in the cochlea moves
5. sound waves enter the external auditory canal
(a) 5, 4, 3, 2, 1
(b) 1, 2, 3, 4, 5
(c) 5, 1, 2, 4, 3
(d) 5, 2, 1, 3, 4

Option C,    5, 1, 2, 4, 3

Explanation:

The first interaction of sound wave is with the outer ear from where it passes through the external auditory canal. After passing through this external canal the sound wave reaches the eardrum where it vibrates ear ossicles . The ear ossicles are the three tiny bones found in the middle ear. The middle ear amplifies the sound vibration and send it to the cochlea filled with fluid. The fluid within cochlea ripples thereby producing waveform that travel through the sensory hair cells and reaches the auditory nerves.

Hence, option C is correct.
