Q

course of vesticulocerbellum

A

to flocculonodular lobe

18
Q

what is immediately below the vesticulocerebellum

A

some go to deep cerebellar nuclei, majorty to vesticular nuclei in brainstem

19
Q

function of corticopontocerebellar pathway

A

motor instructions from cerebral cortex

20
Q

where does proprioceptive info comes from

A

spinocerebellar tracts and vesticular nucli

21
Q

function of dentirubrothalamic pathway

A

send info up from cerebellum to cerebral cortex

22
Q

how do you fine tune actions (what tracts)

A

vestibulospinal, rubrospinal, reticulospinal

23
Q

function of superior peduncle

A

communicate with midbrain

24
Q

function of middle peduncle

A

communicate with pons

25
function of inferior peduncle
helps cerebellum communicate with medulla
26
function of vertibulocerebellum
balance and equilibrium | coordination of eye and head movement
27
input of vestibulocerebellum
vestibular system
28
output of vestibulocerebellum
vestibular nuclei vestibulospinal tracts medial long fasciculus
29
what CN does MLF connect
II, IV, VI
30
function of spinocerbellum
adjusting movement based upon proprioceptive feedback | posture and muscle tone
31
input to the spinocerebellum
dorsal and ventral spinocerebellar tracts, cuneocerebellar, trigeminocerebellar tracts
32
output from the spinocerebellum
vestibospinal and reticulospinal tracts
33
function of the cerebocerebellum
preparation for movement | precise coordination of motor compains
34
input to the cerebrocerebellum
corticopontocerebellar tract | olivocerebellar tract
35
output from the cerebrocerebellum
dentorubrothalamic tract | rubrospinal tract
36
what are the 3 histological cortical layers
molecular layer purkinje layer granular layer
37
functino of purkinje cells
inhibitory to deep cerebellar nuclei
38
function of deep cerebellar nuclei
excitotry
39
actino of climbing fibers from inferior olive
excitatory to purkinhe cells
40
action of mossy fibers
excitatory
41
function of inferior olivary nucleus
proceduar learning
42
if you get a lesion in the cereellum what happens
no paralysis
