Question

where would you expect to find the otolithic membrane?

a. scala vestibuli
b. utricle and saccule
c. ampullae
d. scala media

what is the name for this anatomical part?

Explanation:

Identify location of otolithic membrane

The otolithic membrane is a gelatinous structure containing calcium carbonate crystals (otoliths). It is located in the maculae of the vestibular system, specifically within the utricle and saccule, which detect linear acceleration and gravity.

Identify the pointed anatomical structure

The second question shows an anatomical diagram of the inner ear. The black arrow points directly to the snail-shell-like structure responsible for hearing, which is the cochlea.

Relate to auditory physiology

Using the Auditory Physiology knowledge point, we recognize that while the cochlea processes sound waves, the vestibular apparatus (including the utricle, saccule, and semicircular canals) is dedicated to equilibrium.

Answer:

Question 1

• a. scala vestibuli
• b. utricle and saccule (Correct answer)
• c. ampullae
• d. scala media

Question 2

Cochlea
