cerebellum Flashcards
1
Q
what does cerebellum do
A
Error correction, difference between intent and actual, influences UMN
2
Q
2 main gray matter structures
A
Laminated cerebellar cortex and Deep cerebellar nuclei
3
Q
main source of output?
A
Deep cerebellar nuclei
4
Q
how is output integrated
A
with input from cerebellar cortex before
being sent to UMNs in the cerebral cortex
5
Q
Cerebrocerebellum characteristics
A
- largest
- lateral
-receives directly from cerebral cortex
-reg of high skill(speech/planning)
6
Q
Spinocerebellum characteristics
A
- medial
-receives from spinal cord
-medial-lateral reg of muscles
7
Q
Vestibulocerebellum
A
- caudal-inferior
- input from vestibular nuclei
- reg of posture and equilibrium
- vestibulo-ocular reflex
8
Q
pathways called what
A
cerebellar peduncles
9
Q
middle cereb peduncle
A
- afferent
- input via contralateral pontine nuclei
10
Q
inferior cereb peduncle
A
- afferent from vestibular nuclei, spinal cord, and brainstem
-efferent to vest nuclei, and reticular form(sleep-wake, cardiovas)
11
Q
Superior cerebellar peduncle
A
- Efferent pathway
- deep cereb nuclei projections to thalmus and UMNs in superior colliculis
12
Q
A
