Exploration of the cerebellum and brain stem from the medial aspect

Medullary substance of cerebellar hemisphere

The dissection illustrates the manner in which systems of fibers connect the cerebellar cortex with subjacent structures, either as corticofugal fibers passing toward the dentate nucleus (2) or as corticopetal fibers ascending from the restiform body and brachium pontis.

1 .	Medullary substance of culmen
2 .	Dentate nucleus (visible between bundles of fibers)
3 .	Medullary substance of central lobule
4 .	Branch of superior cerebellar artery
5 .	Commissural fibers of cerebellum
6 .	Brachium conjunctivum (superior cerebellar peduncle) (cut across)
7 .	Lateral lemniscus
8 .	Position of motor and main sensory nuclei of trigeminal nerve
9 .	Area acustica
10 .	Medial lemniscus
11 .	Position of facial colliculus
12 .	Root of trigeminal nerve (V)
13 .	Primary fissure
14 .	Declive of cerebellum
15 .	Folium vermis
16 .	Tuber vermis
17 .	Pyramid (vermis)
18 .	Medullary substance of uvula (cut across)
19 .	Fastigium
20 .	Tonsil (ventral paraflocculus)
21 .	Posterior inferior cerebellar artery
