Answer 1

inf peduncle

Question 2

ventral spinocerebellar tract from spinal cord to cerebellum via…

Answer 2

sup peduncle

Question 3

cuneo spinocerebellar tract from spinal cord to cerebellum via…

Answer 3

inf peduncle

Question 4

rostral spinocerebellar tract from spinal cord to cerebellum via…

Answer 4

inf peduncle

Question 5

input to cerebellum from cortex via… to…

Answer 5

contralateral middle peduncle, all esp. lateral hemisphere

Question 6

input to cerebellum from vestibular nuclei (balance) via… to…

Answer 6

ipsilateral inf. peduncle, flocculonodular lobe

Question 7

input to cerebellum from reticular formation (modulation of volitional movement) via… to…

Answer 7

ipsilateral inf. peduncle, all

Question 8

input to cerebellum from inf. olivary nucleus via… to…

Answer 8

contralateral inf. peduncle, all (as climbing fibres) –> all info into and out of cerebellum must pass through ION

Question 9

output from lateral hemisphere cerebellum from.. nucleus to… peduncle to… destination

Answer 9

denate, sup peduncle, cerebral cortex via thalamus (preprogamming mvmt)

Question 10

output from paravermal cerebellum from.. nucleus to… peduncle to… destination

Answer 10

emboliform and globose, sup peduncle, lateral descending pathways (distal execution of mvmt)

Question 11

output from vermal cerebellum from.. nucleus to… peduncle to… destination

Answer 11

fastigial, inf peduncle, medial descending pathways (axial execution of mvmt)

Question 12

output from flocculonodular cerebellum from.. nucleus to… peduncle to… destination

Answer 12

fastigial, inf peduncle, vestibular nuclei and reticular formation (posture,balance,eye mvmt co-ordination)
