Chapter 39. The Control of Gaze

  1. The near response consists of
    1. Accomodation and pupillary constriction
    2. Vergence, accomodation and pupillary constriction
    3. Retinal disparity, vergence, accomodation and pupillary constriction
    4. Paradoxical accomodation
  2. The movement illustrated is an example of
    1. Intorsion
    2. Extorsion
    3. Elevation
    4. Depression
 eye movement
  1. With the eye in an adducted position, elevation is primarily the responsibility of the
    1. Superior rectus
    2. Inferior rectus
    3. Superior oblique
    4. Inferior oblique
  2. A skew deviation and a head tilt to the right may indicate a lesion affecting the
    1. Oculomotor nerve
    2. Abducens nerve
    3. Trochlear nerve
    4. Optic ganglion
  3. This is a diagram of neuronal firing patterns during a horizontal saccade. Match the firing pattern with the most likely anatomic location of the neuron (4 points).
    1. PPRF
    2. Nucleus prepositus hypoglossi
    3. Nucleus of the dorsal raphe
    4. Abducens nucleus
 eye movement neuronal firing
  1. Which of the following is not involved in horizontal saccadic eye movments?
    1. Frontal eye fields
    2. Substantia nigra
    3. Superior colliculus
    4. Dentate nucleus
