Auditory System Quiz

What is the main job of the pinna?

• Help detect pitch

• Collect and direct sound into the ear canal

• Convert sound to electrical impulses

• Control ear pressure

The auditory canal protects the ear using:

• Earwax and small hairs

• Tiny bones

• Stereocilia

• The cochlea

What happens when sound waves hit the tympanic membrane?

• It produces earwax

• It vibrates and converts sound waves into mechanical energy

• It sends signals to the brain

• It balances air pressure

What are the three ossicles called?

• Cochlea, oval window, and basilar membrane

• Malleus, incus, and stapes

• Eardrum, canal, and cochlea

• Hammer, cochlea, and nerve

The ossicles help by:

• Amplifying and transmitting vibrations

• Detecting balance

• Creating nerve impulses

• Protecting the cochlea

The Eustachian tube connects the middle ear to the:

• Brain

• Nose

• Throat

• Inner ear

The oval window connects to which part of the ear?

• Tympanic membrane

• Cochlea

• Auditory nerve

• Vestibular system

What is the main function of the cochlea?

• Balance air pressure

• Turn sound vibrations into nerve signals

• Transmit vibrations to the eardrum

• Amplify sound waves

The auditory vestibular nerve:

• Controls balance and sends sound signals to the brain

• Produces mechanical vibrations

• Detects pressure changes

• Opens TRPA1 channels
