Prof. SHD*CEREBELLUM:- Berkembang dari metencephalon, bersama-sama dng Pons Varolli- Bersama-sama dng Pons Varoli dan medulla oblongata membatasi ventriculus quartus- Dipisahkan oleh tentorium cerebelli dng hemispherium cerebri; di atas vermis terdpt falx cerebelli- Vasc.: - a.cerebelli inf.or post.or (a.vertebralis) - a.cerebelli inf.or ant.or (a.basilaris) - a.cerebelli superior (a.basilaris)

Prof. SHD

Prof. SHD*STRUKTUR CEREBELLUM:- Cortex cerebelli (= subst.grisea)- stratum moleculare- stratum ganglionare- stratum granulare- Corpus medullare (= subst.alba)- massa nuclei : - nucl.dentatus - nucl.emboliformis- nucl.globosus- nucl.festigii
