E3 cerebellum Flashcards
primary fissure
separates anterior and posterior lobes
posterolateral fissure
separates posterior and floculonodular lobes
floculonosudlar lobe
balance and eye movements
3 layers
molecular
purkinje
granule
3 nuclei
fastigial
interposed
dentate
inhibitory cells
basket, golgi, stellate purkinje
excitatory cell
granule
molecular layer
basket and stellate cells
dendirtes of purkinje
climbing fibers
purkinje layer
cell bodies of only output
granule
golgi and granule cells
mossy fibers
climbing fibers
from inferior olive via ICP excite deep nuclei and purkinje cells 1 collateral per purkinje 1-10 collaterals function=motor adaptaion and motor learnign
mossy fibers
inform cerebellum about planned and ongoing movements
from spinal cord and brainstem
to deep nuclei and granule cells
parallel fibers
from granule cells (activated by mossy fibers)
to purkinje dendrites
excitatory
simple cerebellum circuit
intended and ongoing info in via mossy and climbing fibers to cerebellar cortex and deep neurons
differences between planned and actual analyzed and adjuted and sent out thorugh purkinje fibers
somatotopy of cerebellum
head neck trunk in vermis sent down to fastigial nuclei arms and legs laterally in paravermis and lateral hemispheres to interposed and dentate dual reps in anteror and posterior lobes
