ANATOMY- cerebellum Flashcards
where in the skull is the cerebellum found?
in the posterior cranial fossa of the skull
what attaches the cerebellum to the brainstem?
the cerebellum attaches to the brainstem via 3 stalks found on the inferior aspect
3 stalks AKA peduncles (superior, middle and inferior)
how is the cerebellum seperated from the occipital and temporal lobes?
it is seperated by the tentorium cerebelli (tough layer of dura mater ‘tent of cerebellum’
what are peduncles ?
a bundle of fibres connecting cerebellum and brain stem
what peduncle connects the cerebellum to the midbrain?
superior peduncle
what peduncle connects the cerebellum to the pons?
middle peduncle
what peduncle connects the cerebellum to the medulla oblangata?
inferior peduncle
what are the lobes of the cerebellum?
anterior, posterior and flocculonodular lobe
what are 1, 2 and 3 (superior surface of cerebellum)
1= anterior lobe
2= primary fissure
3= posterior lobe
what seperates the anterior and posterior lobe of the cerebellum?
the primary fissure
anterior lobe= behind primary fissure
what makes up the inferior surface of the cerebellum?
posterior lobe
what seperates the posterior lobe and the flocculonodular lobe?
the posterolateral fiss
what is yellow, orange, red, green and blue?
yellow= anterior lobe
orange= primary fissure
red= posterolateral fissure
blue= flocculonodular lobe
green= posterior lobe
(this is a pic of cerebellum flattened out)
Name the parts
orange= superior vermis
yelllow= anterior lobe
red= primary fissure
green= posterior lobe
light blue= inferior vermis
dark blue= flocculonodular lobe
pink= posterolateral fissure
pruple= horizontal fissure
what is the ‘Arbor Vitae’ or ‘Tree of life’ in the cerebellum?
-white matter that lies within the center of the cerebellum
-it looks like a tree
-there is some grey matter deep to this
