1. The cerebellum Location:
in the posterior cranial fossa; posterior to the medulla and pons;
inferior to the occipital lobes of cerebrum;
separated it from cerebrum with transverse fissure and the
tentorium cerebelli.

3. The lobes of cerebellum: 3 lobes
anterior lobe (oldest part) : vestibulocerebellum
posterior lobe (phylogeneticaly is older part to appear): spinocerebellum

9. The function of cerebellum
superior cerebellar peduncle: brachium conjunctivum
efferent fibers--- from the globose, emboliform and dentate nuclei
(dentatorubral tract, dentatothalamic tract)
afferent fibers--- anterior spinocerebellar tract
The function of cerebellum
Maintain the equilibrium of the body.
Keep good muscular tone
Coordinate the movements of the m..
