Brain stem Flashcards
what is the facial colliculus
bulging fibres of facial nerve looping around abducens nucleus (CN6)
superior cerebellar peduncles aka
brachium conjunctivum
middle cerebellar peduncle aka
brachium pontis
inferior cerebellar peduncle
restiform
what nerve goes through superior medullar velum
trochlear nerve
2 main fissures of cerebellum on convex
anterior lobe primary issue middle lobe horizontal fissure posterior lobe posterolateral fissure flocconodular lobe
vermis lobules and fissures
lingula precentral fissure central preculminate fissure culmen primary fissure declive posterior superior fissure(SPF) folium great horizontal fissure tuber and folium prepryamidal fissure pyramis secondary fissure uvula posterlateral fissure nodulus
which is midline and which is lateral of floccolonodular
nodulus is midline
flocculus is lateral
what fissure separates anterior lobe and posterior lobe
primary fissure
what seperates middle and posterior lobe
great horizontal lobe
what separates posterior lobe and flocculonodular lobe
posterolateral fissure
what fissure separates culmen from declive
primary fissure
fissure separating folium and tuber
horizontal fissure
fissure separating pyramis and uvula
secondary fissure
posterior (occipital) surfaces great horizontal fissure separates
superior semilunar lobules and inferior semilunar lobules
vermis from anterior to posterior
culmen
declive
folium
tuber
fissure separating declive and folium
superior posterior fissure(SPF)
neocerebellar syndrome
movements are ataxia- intermittent or jerky dymetria- overshoots or deviates away disdiadochokinesia asynergy- mechanical movements hypotonia intention tremor dyarthria- monotonous speech
vestibulocerebellum
muscle tone in response to vestibular stimuli- maintain equilibrium
spinocerebellum
adjustment of posture - proprioception
pontocerebellum
afferent from pontine nuclei
hemispheric of lingula
wings
hemispheric of central lobule
ala
hemispheric of culmen
anterior quadrangular lobe
