Cerebellar Hypoplasia
Rostral View
Components: [NOTE: * = not paired]
Cerebellum* . . . (connected to brainstem by peduncles)
Pons . . .* (part of the brainstem)
Cerebellar Components/Regions:
• cerebellar vermis* - median region ("worm-like")
nodulus* (most caudal lobule of the vermis)
• cerebellar hemispheres - bilateral regions
flocculus (most ventrolateral lobule of the hemisphere)
• cerebellar peduncles - rostral, middle, & caudal
Cerebellar Surface Features . . .
Ventral surface: (when removed from pons)
• cerebellar peduncles (three peduncles merged)
• flocculonodular lobe (consists of the nodulus and
bilateral tracts connecting to flocculi)
Dorsal surface:
• cerebellar vermis*
• cerebellar hemispheres
Median surface:
• cerebellar vermis*
• nodulus*
Typical-Section Features:
• cerebellar cortex
-sulci (grooves)
- folia (ridges)
• cerebellar white matter
- cerebellar peduncles
• three cerebellar nuclei
- fastigeal nucleus
- interpositus nucleus
- dentate nucleus
