cerebellum Flashcards
1
Q
nuclei of cerebellum from lateral to medial
A
dentate, emboliform, globose, fastigial
2
Q
what is the efferent cell of the cerebellum? does it code position
A
purkinje cell. No vector, just speed
3
Q
where does the purkinje cell receive input from and what kind? ipsi or contralateral? Via?
A
instruction from climbing fibers. Mossy fibers>parallel fibers>purkinje. (limb position). Both are IPSILATERAL via inferior peduncle
4
Q
function of middle peduncle
A
contralateral cortex input
5
Q
superior peduncle
A
info from purkinje fibers (and deep nuclei) to contralateral cortex
6
Q
Lateral cerebellar fxn? injury? Medial cerebellar (vermis)?
A
voluntary movement of extremities; propensity to fall toward injured side (ipsilateral). Medial is balance, truncal coordination
