1

cerebellum fxn

planning and fine tuning muscle contractions

2

cerebellum from....

metoncephalon

3

cerebellum parts

vermis (midline)
2 intermediate hemispheres
2 lateral hemispheres
flocculonodular lobe

4

vermis fxn

axial and proximal limb muscles

5

intermediate fxn

distal musculature

6

lateral fxn

motor planning

7

which parts influence CST

lateral and intrermediate

8

flocculonodular lobe fxn

balance and eye mvmts

9

input for vermis

spinal cord

10

input for intermediate

spinal cord

11

input for lateral

cerebral cortex
inferior olivary nuc

12

input for flocculonodular

vestibular nuclei (VIII)

13

tracts out

SCP
superior cerebellar peducle

14

tracts in

inferior cerebellar peduncle (ICP)
middle cerebellar peduncle (MCP)

15

cells that leave cerebellum (have influence)

purkinje cells

16

cells that leave cerebellum (have influence)

purkinje cells

17

NTs in cerebellum

all cells use GABA except granulse cells (glutamate)

18

cells in cerebellum

purkinje
granule cells
stellate cells
basket cell
golgi cell

19

fibers in cerebellum

climbing (from olivary nuc)
mossy (from spinal cord, pontine, vestibular)

20

fibers in cerebellum

climbing (from olivary nuc)
mossy (from spinal cord, pontine, vestibular)

21

deep nuclei

lateral: dentate

22

cerebellar lesion (side)

ipsilateral

23

cerebelllum lesion theme

tremor w/ mvmt

24

vermis lesion sx

difficult ot maintain posture/balance
motor/cerebellar ataxic gait

25

motor ataxia vs sensory ataxia

motor has Romberg sign

26

Romberg sign

sway when close eyes (no more visual help)

27

cerebellar hemisphere lesion

intention tremor w/ voluntary mvtmt
mostly fine @ rest
dysmetria
dysdiadochokinesis

28

dysmetria

can't stop mvmt at right place (measure)
use finger to nose test

29

dysdiadochokinesis

can't perform rapidly alternating mvmts

30

flocculonodular lobe lesion sx

scanning dysarthria
abnormal conjugate gaze
