Understanding the Ear

What is the cochlea and what is its primary function?

• A membrane that vibrates when sound waves hit it

• A part of the outer ear that collects sound waves

• A spiral-shaped organ in the inner ear that helps in hearing

• A bone in the middle ear that transmits sound

Which part of the ear is responsible for collecting sound waves and funneling them to the eardrum?

• Inner ear

• Middle ear

• Outer ear

• Auditory nerve

What is the role of the eardrum in the hearing process?

• It transmits sound directly to the brain

• It helps maintain balance

• It vibrates when sound waves hit it, transmitting vibrations to the middle ear

• It produces earwax to protect the ear canal

What is the primary function of earwax?

• To protect the ear canal from dirt and infections

• To convert sound waves into nerve impulses

• To transmit sound vibrations

• To help maintain balance

Which tiny bones in the middle ear are responsible for transmitting sound vibrations?

• Cochlea, auditory nerve, and semicircular canals

• Cartilage, cochlea, and eardrum

• Eardrum, ear canal, and pinna

• Hammer, anvil, and stirrup

How does the cochlea contribute to the hearing process?

• It collects sound waves from the environment

• It vibrates to transmit sound to the middle ear

• It converts sound vibrations into nerve impulses

• It maintains air pressure in the ear

What is the function of the auditory nerve?

• To collect sound waves

• To maintain balance

• To transmit sound vibrations to the middle ear

• To carry nerve impulses from the cochlea to the brain

What role do the semicircular canals play in the ear?

• They produce earwax to protect the ear

• They vibrate to transmit sound to the cochlea

• They maintain balance by detecting head movements

• They help in hearing by transmitting sound

How does the inner ear help maintain balance?

• By collecting sound waves

• By sending signals to the brain about head movements

• By vibrating in response to sound

• By producing earwax

What happens when the fluid in the semicircular canals moves?

• It causes the eardrum to vibrate

• It sends signals to the brain about balance

• It transmits sound to the cochlea

• It produces earwax
