Question 1

function

Answer 1

1. coordinate precise motor function
2. procedural memory

Question 2

components of motor function

Answer 2

1. velocity
2. force
3. duration
4. timing
5. trajectory

Question 3

flocculonodular lobe

Answer 3

flocculus + nodulus

superior part of ventral side

Question 4

zones

Answer 4

1. spinocerebellum = vermal + paravermal
2. vestibulocerebellum
3. hemispheric/lateral/cerebro-cerebellum

Question 5

deep cerebellar nuclei

Answer 5

1. fastigial @vermal zone
2. globose
3. emboliform
4. dentate (biggest and most lateral)

all are paired

Question 6

major inputs

Answer 6

1. spinocerebellum
2. cerebrocerebellum
3. vestibulocerebellum

Question 7

spinocerebellum pathway

Answer 7

1. spinal cord
2. vermis > fastigial nucleus
3. or paravermal > interposed nuclei

Question 8

cerebrocerebellum pathway

Answer 8

1. cerebral cortex
2. hemispheric zone
3. dentate nucleus

Question 9

vestibulocerebellum pathway

Answer 9

1. vestibular receptors/system
2. flocculonodular lobe
3. vestibular nuclei + vestibulospinal tracts + medial longitudinal fasciculus (III, IV, VI)

Question 10

vestibulocerebellum function

Answer 10

1. balance and equilibrium (anti gravity muscles)
2. coordination of eye and head movements

Question 11

spinocerebellum inputs

Answer 11

1. dorsal and ventral spinocerebellar tracts
2. cuneocrebellar
3. trigeminocerebellar tracts

Question 12

spinocerebellum outputs

Answer 12

1. vestibulospinal
2. reticulospinal tracts

Question 13

spinocerebellum functions

Answer 13

adjust movements based on proprioceptive feedback from axial and proximal muscles of trunk and limbs
-posture and muscle tone
