Semester 2 Neuro, Quiz 2 - Cerebellum
.
- 1.A 70-year old man with a history of hypertension went to work and had sudden onset of nausea and vomiting. He was taken to ER, where his exam was notable for slurred speech, dysmetria on finger-to-nose testing on the left side. His gait was normal. Where is the lesion?
- A.
Cerebellar vermis
- B.
Right cerebellar hemisphere
- C.
Left cerebellar hemisphere
- D.
Fastigial nucleus
- E.
Vestibular nuclei
- 2.A 45-year-old man was admitted to the hospital with a cerebellar hemorrhage. The patient exhibited an unsteady "drunk like" gait and the physician noted that he swayed while entering the examination room. Which region of the cerebellum was most likely affected by the bleed?
- A.
Hemispheres of the anterior lobe
- B.
Hemisphere of the posterior lobe
- C.
Interposed nuclei
- D.
Dentate nucleus
- E.
Flocculonodular lobe
- 3.Dysdiadokmesia refers to which of the following?
- A.
Inability to perform the Tandem-Gait test
- B.
Inability to stand without swaying with eyes open
- C.
Inability to control distance, power or speed of a movement
- D.
Inability to control vestibulo-ocular reflexes
- E.
Inability to perform rapid alternating movements with the hands
- 4.Concerning the circuitry between mossy fibers, climbing fibers and cells of the cerebellar cortex, which of the following pairs both provide excitatory input?
- A.
Mossy fibers & Purkinje cells
- B.
Purkinje cells & Golgi cells
- C.
Granule cell parallel fibers & Mossy fibers
- D.
Golgi cells & Climbing fibers
- E.
Climbing fibers & Basket cells
- 5.As a researcher studying the circuitry of the cerebellum, which of the following nuclei do you wish to lesion if you are focusing mainly on the flocculo-nodular lobe circuitry of the cerebellum?
- A.
Fastigial nucleus
- B.
Dentate nucleus
- C.
Clarkes nucleus
- D.
Spinal border cells
- E.
Globose nucleus
- 6.Your 27-year old patient displays ataxia when asked to walk across the examination room. You ask him to stand still with his eyes closed and note marked swaying back and forth. When he opens his eyes the swaying persists. Vibration sense is normal on all four limbs. Given the clinical picture in this case, such ataxia is likely due to damage to which of the following structures?
- A.
Dorsal columns
- B.
Cerebral peduncles
- C.
Posterior limb of the internal capsule
- D.
Ventral horns of the spinal cord
- E.
Cerebellum
- 7.Efferent axons from the dentate nucleus terminate in what thalamic nucleus and travel through what peduncle?
- A.
Ventral anterior nucleus of the thalamus (VA) ---superior cerebellar peduncle
- B.
Ventral anterior nucleus of the thalamus (VA) ---middle cerebellar peduncle
- C.
Ventral lateral nucleus of the thalamus (VL) ---superior cerebellar peduncle
- D.
Ventral lateral nucleus of the thalamus (VL) ---middle cerebellar peduncle
- E.
Ventral posterolateral nucleus of the thalamus (VPL) ---superior cerebellar peduncle
- 8.As a researcher studying the circuitry of the cerebellum, which of the following nuclei do you know to be the major output neuron of the cerebellar cortex?
- A.
Purkinje cells
- B.
Dentate nucleus
- C.
Fastigial nucleus
- D.
Clarke's nucleus
- E.
Spinal border cells
- 9.
