Answer 2

1. Superior cerebellar peduncle
   (efferent info)
2. Middle cerebellar peduncle (allows it to pass)
3. Inferior cerebellar peduncl (afferent)

Question 3

what are the fissures of the cerebellum

Answer 3

Question 4

3 functional divisions of the cerebellum

Answer 4

cerebrocerebellum

spinocerebellum

vestibulocerebellum

Question 5

What happens in the cerebrocerebellum / lateral

Answer 5

Input: from cerebral cortex + pontine nucleus
= muscle activation/ planning

nuclei: DENTATE

Question 6

What happens in the spinocerebellum / vermis + intermeidate

Answer 6

input: proprioceptive info
= regulating body movements

nuclei:
limb = interposed nucleus (vermis)
Postural = fastigial and vestibular nucleus (intermediate)

Question 7

what happens in the Vestibulocerebellum/flocculonodular lobe

Answer 7

input: vestibular system
= balance, relaxs

nuclei: vestibular nuclei

Question 8

what are the nuclei of the cerebellum

Answer 8

Medial to lateral
1. Fastigial
2. globose (interpositus)
3. emboliform (interpositus)9
4. dentate

Question 9

Answer 9

Superior cerebellar art. (SCA)
Anterior inferior cerebellar art. (AICA)
Posterior inferior cerebellar art. (PICA)
Basilar art.
Pontine art.
