cerebellum Flashcards
(29 cards)
where is cerebellum
posterior cranial fossa
under tent cereblli
embryonically, cerebellum is related to what
pons
cerebellum is connect to what
brainstem through 3 cerebellar peduncles
whats between pons and cerebellum
4th ventricle
lobes of cerebellum
anterior
posteiror
flocculondular
functional areas of cerebellum
spinocerebllum
cerebrocerebellum
vestibulocerebellum
wheres spinocerebellum
anterior lobe
vermis
paravermis
wheres cerebrocerebellum
posterior lobe
wheres vestibulocerebellum
flocculus nodule
parts of cerebellum
flocculus nodule paravermis vermis cerebellar tonsils cerebellar peduncles
name the three cerebrally peduncles
super middle inferior
whats main output nucleus from cerebellum
dentate nucleus
superior cerebellar peduncle
afferent
anterior spincerbellar tract
acoustic / optic info
superior cerebellar peduncle
efferent
dentatorubrothalmic tract
dentatothlaamic tract
middle cerebellar peduncle
afferent
ponotcerebllar tract
does middle cerebellar peduncle do efferent
no
inferior cerebellar peduncle
afferent
vestibulocerebllar tract
olivocerebellar tract
posterior spinocerebllar tract
inferior cerebellar peduncle
efferent
cerebello vestibular tract
cerebella olivary tract
3 function loops
vestibulocerebllar
spinocerebllar
cerebrocerebellar
vestibulocerebllar loop
coordinate balance
vestibulo-ocular reflex
output to LMN for trunk / limb stability
spinocerebllar loop
coordination and correction of trunk n limb movement
cerebrocerebellar loop
streamline cortical output
projections from vestibular nuclei to returciular formation do what
go to SC for trunk stability and influence anti gravity mm
input from cortex to cerebellum relayed through what
pontine nuclei
