Question one:
Match the correct letter with each description:
Sound waves are transduced in this part of the ear.

Exposure to loud noise can cause damage to this area of the ear and can result in nerve deafness, which cannot be helped by a hearing aid.

If this part of the ear is damaged or becomes brittle (as sometimes happens in old age), the result is conduction deafness, which can be helped by a hearing aid.

Sound waves are amplified in this part of the ear.

Sound waves are collected in this part of the ear.

Sound waves are transformed into coded neural messages here.
Question 2:
Match the correct letter with each description:

This structure transmits amplified vibration to the oval window.

This structure separates the middle ear from the inner ear.

Motion sickness is related to this structure

This structure contains vestibular sacs and provides our sense of balance.

The name of this spiral shaped fluid-filled tube comes from the Greek word for "snail."

Collects sound waves (A, B, or C)

Amplifies sound waves (A, B, or C)

This structure contains the basilar membrane and hair cells, where transduction takes place.

Made up of tiny bones called the hammer, the anvil, and the stirrup, which serve to amplify sound waves.

Transduction of sound waves into neural messages occurs here (A, B, or C)

This structure separates the outer ear from the middle ear.
Question 3:
Match the ear structure with the appropriate letter in the diagram below:

semicircular canals

cochlea

auditory nerve

ear canal

middle ear

pinna

inner ear

oval window

anvil

eardrum

outer ear

stirrup

hammer
