Ear Structure, Balance, and Hearing

1. What is the function of the outer ear?

• Collect and direct sound waves into the ear canal

• Regulate body temperature

• Store memories

• Filter out harmful bacteria

2. Which part of the ear is responsible for maintaining balance?

• Eardrum

• Cochlea

• Vestibular system

• Auditory nerve

4. What is the function of the cochlea in the ear?

• Regulate body temperature

• Convert sound vibrations into electrical signals

• Detect light waves

• Produce earwax

5. Which part of the ear is responsible for converting sound waves into electrical signals?

• cochlea

• eardrum

• retina

• cerebellum

6. Label the parts of the ear: Pinna, Ear Canal, Eardrum, Cochlea, Auditory Nerve

• Pinna, Ear Canal, Eardrum, Cochlea, Auditory Nerve

• Pinna, Ear Canal, Eardrum, Stapes, Auditory Nerve

• Eye, Ear Canal, Eardrum, Cochlea, Auditory Nerve

• Pinna, Ear Canal, Eardrum, Nose, Auditory Nerve

7. What is the purpose of the semicircular canals in the ear?

• Filtering sound waves

• Regulating body temperature

• Maintaining balance and orientation

• Enhancing sense of taste

8. What is the role of the auditory nerve in the hearing process?

• Producing sound waves in the inner ear

• Transmitting electrical signals from the inner ear to the brain

• Regulating the balance of fluids in the ear

• Filtering out unnecessary background noise

9. Which part of the ear is responsible for amplifying sound waves?

• Outer ear

• Nose

• Inner ear

• Middle ear

10. What is the function of the middle ear?

• Transmit sound

• Aid in digestion

• Store excess sound waves

• Regulate body temperature

12. How does the inner ear help with balance?

• It regulates body temperature

• It helps with taste perception

• It assists with breathing

• It contains the vestibular system, which detects changes in head position and movement.
