- Cerebellar vermis
The vermis (pl: vermes) of the cerebellum is an unpaired medial structure that separates the cerebellar hemispheres. Its anatomy broadly follows that of the cerebellar hemispheres.
Gross anatomy
The vermis is separated into a small anterior lobe and a much larger posterior lobe by the primary fissure. It can be further subdivided into nine lobules which are formed by groups of folia (sing: folium) that correspond to paired cerebellar hemisphere lobules. These are subject to variability in terms of their size, shape and number of folia 1-4.
- anterior lobe
- lingula
- central lobule
- culmen
- primary (tentorial) fissure
- posterior lobe
- declive
- folium
- horizontal (petrosal) fissure
- tuber
- prebiventral/prepyramidal (suboccipital) fissure
- pyramid
- uvula
- flocculonodular lobe
- nodulus
A helpful mnemonic to remember the lobules of the vermis can be found here.
