Cerebellum

Question 1

Vermis

Answer 1

Fastigial vestibular

• motor function- balance, eye movement, reflexes
• cognitive function- autonomic arousal, limbic regulationg

Question 2

Intermediate

Answer 2

Paravermal hemisphere

• motor function- sensorimotor integration, movement execution
• cognitive function- simple verbal responses to commands

Question 3

Lateral

Answer 3

Lateral hemisphere
-motor function- prep and planning movement
fine motor dexterity
eye movements
imagined movements
- cognitive function- verbal association
rule based learning
working memory 
problem solving
monitoring performance
temporal perception

Question 4

Purkinje cells

Answer 4

inhibitory- GABA

control thalamus and motor cortex through the deep nuclei

Question 5

Unilateral lesion to lateral lobes

Answer 5

Asthenia- loss of muscle strength
atonia- loss of muscle tone
Ataxia

Question 6

Asynergia

Answer 6

Difficulty coordinating muscular actions

Question 7

decomposition of movement

Answer 7

complex movements become broken down into single movements

Question 8

Dysmetria

Answer 8

poorly directed movements

intention tremor

Question 9

when executing movements

Answer 9

deviations from the line of movement

desdiadochokinesia

Question 10

Midline cerebellar lesions

Answer 10

Nystagmus
scanning speech
postural disorders

Question 11

Essential tremor

Answer 11

overactivity of the inferior olive
ETOH used GABA- agonist- increases activity of purkinje cells
GLU antagonist- decreases effect of Deep nucleus on thalamus and eventually the cortex
