Ear and Hearing Quiz

What is the function of the cochlea in the ear?

• Moves sound waves through the ear canal

• Detects different tones or frequencies

• Converts mechanical energy of sound into electrical signals

• Causes tension differences in the hair cells

Which part of the ear is responsible for high frequencies?

• Inner ear

• Middle ear

• Base of the cochlea

• Apex of the cochlea

What is the role of the ossicular chain in the ear?

• Detects different tones or frequencies

• Converts sound waves into electrical signals

• Moves sound waves through the ear canal

• Transmits sound vibrations from the ear drum to the inner ear

What causes the movement of the fine structures on the surface of the hair cells in the cochlea?

• Motion of the fluid in the cochlea

• Ossicular chain in motion

• Change in tension differences

• Vibration of the ear drum

What is the main function of the auditory cortex in the brain?

• Converts mechanical energy of sound into electrical signals

• Detects different tones or frequencies

• Moves sound waves through the ear canal

• Interprets electrical signals as sound

Which part of the ear is affected in outer ear hearing loss?

• Hair cells

• Ossicular chain

• Cochlea

• Ear drum

What causes an individual to experience hearing loss?

• Loss of sensitivity in the hair cells

• Change in tension differences

• Motion of the fluid in the cochlea

• Vibration of the ear drum

What is the main function of the ear drum in the ear?

• Receives sound waves and begins to vibrate

• Converts mechanical energy of sound into electrical signals

• Detects different tones or frequencies

• Moves sound waves through the ear canal
