What is the purpose of the eardrum?

• The purpose of the eardrum is to vibrate in response to sound waves and transmit the vibrations to the middle ear.

• The purpose of the eardrum is to filter out unwanted sounds.

• The purpose of the eardrum is to produce sound waves.

• The purpose of the eardrum is to protect the inner ear from infections.

• auditory nerve

• cochlea

• eardrum

• pinna

What is the role of the cochlea in the ear?

• The cochlea converts sound vibrations into electrical signals.

• The cochlea filters out background noise.

• The cochlea helps maintain balance in the ear.

• The cochlea amplifies sound vibrations.

What is the function of the auditory nerve?

• Transmit visual signals from the retina to the brain.

• Regulate blood flow in the brain.

• Control muscle movement in the limbs.

• Transmit sound signals from the cochlea to the brain.

What happens when sound waves reach the cochlea?

• The sound waves are absorbed by the cochlea and do not cause any vibration.

• The sound waves cause the fluid in the cochlea to vibrate, stimulating the hair cells.

• The sound waves pass through the cochlea without any effect.

• The sound waves cause the cochlea to shrink and become less sensitive to sound.
