Cerebellum Flashcards
Cerebellar tonsils is found in which part of the cerebellum?
Posterior
vestibullocerebellum vs spinocerebellum vs cerebrocerebellum
corresponds to the flocculonodular lobe
vestibulocerebellum
for body equilibrium and eye movement
vestibullocerebellum vs spinocerebellum vs cerebrocerebellum
corresponds to the anterior lobe
spino cerebellum
for muscle tone and axial and limb movement
vestibullocerebellum vs spinocerebellum vs cerebrocerebellum
corresponds to the posterior lobe
cerebrocerebellum or pontocerebellum
for planning and initiation of movement
regulation of discrete limb movement
Phylogenetic divisions of cerebellum, describe
Archicerebellum
flocculonodular lobe
Paleocerebellum
anterior lobe and small part of the posterior lobe
Neocerebellum
posterior lobe
What are the three layers of the cerebellum?
Molecular layer
Purkinje cell layer
Granule cell layer
Only cell that sends axons outside the cerebellum
Purkinje cells
What is the main difference between the basket and stellate cells?
They are similar in input and act on Purkinje cells. However,
stellates: on Purkinje’s dendriates only
basket: on Purkinje’s dendrite, perikarya and axons
vestibular nuclei to the cerebellum
inferior
medial
Describe the relationship between the climbing fiber and Purkinje?
intimate
It is one-to-one
Mossy fiber projection
Deep ONLY Purkinje X Basket X Stellate X Granule ONLY Golgi ONLY
Climbing fiber projection
Deep Purkinje Basket Stellate Granule-- NOT Golgi
Efferents from the cerebellum leave via
inferior and superior cerebellar peduncles
fibers leaving via the inferior cerebellar peduncles
cerebellovestibular
cerebelloreticular
fibers leaving via the superior cerebellar peduncles
cerebellothalamic
cerebellorubral
cerebelloolivary
