Which view of the cerebellum?

Right (inferior); left (superior)

4

What dural extension separates the cerebellum from the inferior occipital lobe?

Tentorium cerebelli

5

Which ventricle is located between the pons and cerebellum?

4th

6

Where is the flocculus

visible on anterior surface just below the middle CP

7

On which surface is the paravermis visible?

Superior

8

Which lobe of cerebellum is largest?

Posterior

9

Which two regions make up the vestibulocerebellum

Flocculus and nodule

10

Which region represents the cerebrocerebellum?

Most of posterior lobe

11

Which structures make up the spinocerebellum?

1) Vermis 2)Paravermis 3)Anterior lobe

12

What are the two afferents to the SUPERIOR cerebellar peduncle?

1) Anterior spinocerebellar tract; 2) Acoustic and optic information

13

What are the two EFFERENTS of the SUPERIOR cerebellar peduncle?

1) Dentatorubrothalamic tract; Dentatothalamic tract

14

What afferent tract travels via the middle cerebellar peduncle (hint: why is the MCP the biggest peduncle?)

Pontocerebellar tract

15

Middle cerebellar efferents?

None!

16

Inferior cerebellar peduncle afferents

Vestibulocerebellar tract; olivocerebellar tract; posterior spinocerebellar tract

17

ICP efferents

Cerebello-vestibular tract; cerebello-olivary tract

18

Which cerebellar nucleus is involved in the vestibulocerebellar loop?

Fastigial

19

Which cerebellar lobe do projections from the pontine nuclei terminate in?

Posterior lobe (contralateral)

20

Which artery supplies the cerebellar peduncles?

AICA

21

Which artery supplies the flocculonodular lobe?

AICA

22

Which arteries supply the posterior lobe?

PICAs and SCA

23

Which artery supplies the tonsils?

PICAs

24

Which artery supplies the anterior lobe?

SCA

25

Which arteries supply the vermis

PICAs (inferior) and SCA (superior)

26

Which arteries supply the deep cerebellar nuclei

Mostly SCA with help from AICAs

27

Lesions to the cerebellum result in

Truncal instability or IPSILATERAL limb deficits

28

What are the 4 deep nuclei from lateral to medial? (don't eat greasy food)

1) Dentate 2) Emboliform 3)Globose 4)Fastigial

29

Which cerebellar region and nucleus are responsible for truncal movements

Vermis + fastigial nucleus

30

Which region (spinocerebellum) is associated with truncal movements

Anterior lobe; efferents via globose and emboliform nuclie
