63. Pupillary reflexes

  1. The consensual light response is reflexive constriction of both pupils when only one eye is illuminated. (T/F?)
  2. Direct light response is normally slightly more vigorous and more marked than indirect, consensual response. (T/F?)
  3. Afferent limb of light reflex arch consist of small fraction of optic tract axons that synapse on the neurons in the Edinger-Westphal nuclei. (T/F?)
  4. Neurons of the Edinger-Westphal nuclei give postganglonic parasympathetic fibers that travel further in the oculomotor nerve. (T/F?)
  5. The tonic (Adie) pupil is larger than unaffected pupil. (T/F?)
  6. Argyll-Robertson pupils show light-near dissociation. (T/F?)

50. Aphasia

  1. Wernicke’s aphasia is also called receptive aphasia. (T/F?)
  2. Wernicke’s aphasia  is characterized by fluent, but nonsensical, oral and written expression. (T/F?)
  3. Broca’s aphasia is expressive aphasia.(T/F?)
  4. Patients suffering from Broca’s aphasia characteristically exhibit so called “telegraphic speech”. (T/F?)
  5. Creation of neologisms is characteristic for Broca’s aphasia. (T/F?)
  6. Global aphasia impacts expressive and receptive language and reading, but not writing. (T/F?)

17. Ataxia

  1. Widespread cerebellar lesions cause more or less symmetrical symptomatology, while localized, unilateral cerebellar lesions cause contralateral hemiataxia. (T/F?)
  2. Worsening of symptoms of ataxia when the eyes are shut indicates absence of sensory ataxia. (T/F?)
  3. Romberg’s test is negative in sensory ataxia. (T/F?)
  4. Scanning speech is typically associated with sensory ataxia. (T/F?)
  5. In tandem Romberg’s test patient places his or her feet in heel-to-toe position with one foot  in front of the other. (T/F?)
  6. Intention tremor is associated with cerebellar ataxia. (T/F?)

  1. Unilateral cerebellar lesions cause ipsilateral hemiataxia.
  2. Sensory ataxia is caused by loss of proprioception, and is worsened when proprioception cannot be compensated by visual input.
  3. Romberg’s test is positive in sensory ataxia.
  4. Scanning speech is a symptom of a lesion in the cerebellum.
