Middle Ear Physiology

Question 1 of 5

1

What are the components of the middle ear?

Select one of the following:

  • Vestibular canal, middle ear muscles, cochlea

  • Cochlea, middle ear muscles, ossicles

  • Eustachian tube, middle ear muscles, cochlea

  • Ossicles, middle ear muscles, Eustachian tube

Explanation

Question 2 of 5

1

What is the function of the ossicles?

Select one of the following:

  • Amplification

  • Decreasing instensity

  • Localisation

  • Protection

Explanation

Question 3 of 5

1

How else does the middle ear increase amplification?

Select one of the following:

  • The middle ear muscles vibrate helping sounds reverberate

  • 17:1 ratio of oval window to tympanic membrane leading to increased intenisity

  • The opening and closing of the Eustachian tube intensifies vibrations

  • The external auditory meatus is funnel shaped increasing amplitude further down

Explanation

Question 4 of 5

1

a) How does the middle ear help protect against loud noises?
b) What is this effective against?

Select one of the following:

  • a) Ossicles send some vibrations back toward tympanic membrane and out the ear
    b) Short term and self-generated sounds

  • a) Middle ear muscles clench around ossicles
    b) Only sounds above 45 deciBels

  • a) Middle ear muscles clench around ossicles
    b) Short term and self-generated sounds

  • a) Ossicles send some vibrations back toward tympanic membrane and out the earb) Only sounds above 45 deciBels

Explanation

Question 5 of 5

1

What is the function of the Eustachian tube?

Select one of the following:

  • Equalize the frequency of most sounds so that they are within the human-hearing spectrum

  • Decrease the intensity of sounds before they reach the inner ear

  • Amplify sounds before they reach the inner ear

  • Equalize pressure build-up in the ear
