Question

Put the following sequence in the correct order:

The outside of the ear catches sound vibrations from the air.
Vibrations from the eardrum are passed on to tiny bones.
Bones pass vibrations on to a liquid inside the ear.
The liquid vibrates.
Nerves in contact with the liquid send a message to the brain.
The brain understands what the sound means.

Answer 1

When sound waves enter the ear, they pass through the ear canal and the eardrum, which vibrates. The vibrations then travel through the three tiny bones of the middle ear and reach the cochlea in the inner ear, where hair cells bend in response to the vibrations. The bending of the hair cells triggers nerve impulses that are transmitted to the brain for interpretation.

Step-by-step explanation:

Hearing is the ability to sense sound waves, and the ear is the organ that senses sound. Sound waves enter the ear through the ear canal and travel to the eardrum. The eardrum vibrates in response to the sound waves, and those vibrations pass through three tiny bones (hammer, anvil, and stirrup) in the middle ear. The vibrations then reach the cochlea in the inner ear, which is filled with liquid. The liquid moves in response to the vibrations, causing hair cells lining the cochlea to bend. The bending of the hair cells triggers nerve impulses, which are relayed to the auditory nerve and then sent to the brain for interpretation.
