Cerebellar disorders

Question 1

The Function of the Vestibulocerebellum, which contains the Flocculonodular Lobe is:

Answer 1

for control of eye movements, balance reactions, and postural control.

Question 2

The Spinocerebellum, which consists of the Vermis and the paravermal area of the anterior and lateral lobes of the Cb is responsible for:

Answer 2

for dynamic control of ongoing movements and acts as “comparator” of intended motor plan and executed movement

Question 3

The Cerebrocerebellum, which consists of the Lateral Cerebellar hemisphere and major afferents from Cerebral Cortex is responsible for:

Answer 3

planning, preparation and prediction of movement, regulates cortical programs, evaluation of sensory information for complex tasks

Question 4

T/F: Isolated damage to the Flocculonodular lobe and vermis usually results in disturbances of equilibrium of the trunk and head-eye movement difficulties. It does not affect the limbs, cause tremor, or significantly affect muscle tone.

Answer 4

TRUE

Question 5

T/F: Damage to the more lateral areas of the Cerebellum usually results in: hypotonia, ataxia, general loss of coordination, dysmetria, intention tremor, dysdiadochokinesia, movement decomposition, scanning speech and dysarthriaimpaired motor learning skills.

Answer 5

TRUE

Question 6

T/F: Nystagmus can occur with damage to anywhere in the cerebellum.

Answer 6

TRUE

Question 7

T/F: If damage to the Cerebellum is primarily in the lateral regions, deficits will be ipsilateral, But can have bilateral or contralateral deficits if damage is more in the intermediate area.

Answer 7

TRUE

Question 8

T/F: The Cerebellum is considered part of the motor system because damage results in motor (coordination and equilibrium) disturbances. Damage here does not result in paralysis or sensory loss.

Answer 8

TRUE

Question 9

T/F: Ataxia is a term that is used to describe any disordered motor function/movements from any pathology.

Answer 9

FALSE

Question 10

Which cerebellar subdivision contains the vermis and paravermis?

Answer 10

Spinocerebellum

Question 11

Which area is the vermis associated with?

Paravermis?

Answer 11

Vermis - trunk

Paravermis - limbs
