Question

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?

Answer 1

The correct order of events of sound transmission through the ear is as follows: sound waves enter the external auditory canal, sound waves strike the eardrum and make it vibrate, ear ossicles vibrate and amplify the vibrations, the perilymph in the cochlea moves, and hair cells of the organ of Corti vibrate.

Step-by-step explanation:

The correct order of events of sound transmission through the ear is as follows:

1. The sound waves enter the external auditory canal.
2. The sound waves strike the eardrum (tympanic membrane) and make it vibrate.
3. The ear ossicles (hammer, anvil, and stirrup) vibrate and amplify the vibrations.
4. The stapes presses into the oval window, causing the perilymph in the cochlea to move.
5. The hair cells of the organ of Corti vibrate in response to the moving perilymph, generating nerve impulses that are transmitted to the brain.

Answer 2

The correct order of events of sound transmission through the ear is;

5. Sound waves enter the external auditory canal

1. Sound waves strike the eardrum

2. The ear ossicles vibrate

4. The perilymph in the cochlea moves

3. Hair cells of the organ of corti vibrate
