Structure of the Ear Quiz

Anatomy of the outer ear: What are the three main parts of the outer ear?

• Nose, Mouth, Throat

• Finger, Hand, Arm

• Eye, Eyebrow, Eyelash

• Pinna, Ear Canal, Eardrum

Anatomy of the outer ear: What is the function of the pinna in the outer ear?

• Collect and direct sound waves into the ear canal

• Regulates the temperature of the ear

• Stores excess earwax

• Helps in balancing the body

Function of the middle ear: What is the role of the three small bones in the middle ear?

• They store excess sound vibrations

• They are responsible for taste perception

• They transmit sound vibrations from the eardrum to the inner ear.

• They help in regulating body temperature

Function of the middle ear: How does the middle ear help in amplifying sound?

• Creating balance in the ear canal

• Transmitting vibrations from the eardrum to the inner ear

• Regulating the temperature of the ear drum

• Producing mucus to protect the inner ear

Structure of the inner ear: What are the main components of the inner ear?

• earlobe, eardrum, and ear canal

• tympanic membrane, oval window, and round window

• hammer, anvil, and stirrup

• cochlea, vestibule, and semicircular canals

Structure of the inner ear: What is the function of the semicircular canals in the inner ear?

• Detect changes in head position and rotational movement

• Regulate body temperature

• Control blood pressure

• Filter out noise

Role of the cochlea in hearing: What is the main function of the cochlea in the ear?

• Filters out unnecessary background noise

• Convert sound vibrations into electrical signals

• Detects changes in air pressure

• Regulates the balance of fluids in the ear

Role of the cochlea in hearing: How does the cochlea convert sound vibrations into electrical signals for the brain?

• The cochlea sends sound vibrations directly to the brain without converting them into electrical signals

• The cochlea amplifies sound vibrations

• The cochlea filters out certain frequencies of sound

• The cochlea contains hair cells that convert sound vibrations into electrical signals.
