Chapter 40. The Vestibular system

    1. Draw a line from the receptor organ to its function
    1. Hair cells
    2. Utricle and saccule
    3. Semicircular canals
    1. Angular acceleration
    2. Linear acceleration
    3. Sound
    1. With the head in a normal position, the macula of each utricle is approximately
      1. Vertical
      2. Horizontal
      3. Diagonally tilted
      4. Opposite
    2. Otoconia are found in the
      1. Utricle and saccule
      2. Vestibular labyrinth
      3. Hair cells
      4. All of the above
    3. The basic life question "which way is up?" is answered by the
      1. Semicircular canals
      2. Utricle
      3. Hair cells
      4. None of the above
    4. The semicircular canals are primarily responsible for the
      1. Rotational vestibulo-ocular reflex
      2. Translational vestibulo-ocular reflex
      3. Ocular counter-rolling response
      4. All of the above
    5. The optokinetic reflex is important for tracking
      1. In the dark
      2. With sustained steady rotation
      3. Neither of the above
      4. Both of the above
    6. If the head and environment are still, firing in the vestibular nerves is
      1. Absent
      2. High
      3. Medium
    7. The patient states "I feel that I'm moving backwards if I stop at a red light and the cars beside me begin to move forward." This suggests that the patient
      1. Has a normally-functioning nucleus of the optic tract
      2. Has an abnormality of the vestibular nucleus
      3. Has a lesion of the magnocellular pathway
      4. All of the above
This is an open-book test due 3/12/2002
A score of 80% or better is required. If your score is less, you are required to retake the test.
