Presentation Transcript

  1. Cerebellum Small brain

  2. Fissures of cerebellum

  3. Lobules of Superior vermis • 1-lingula • 2-central • 3-culmen • 4-declive • 5-foilum

  4. Lobules of inferior vermis • 1-tuber • 2-pyramid • 3-uvula • 4-nodule

  5. Lobules of Superior vermis and hemisphere • 1-lingula • 2-central…………..Ala • 3-culmen………….quadrangular • 4-declive…………..simplex • 5-foilum……………superior semilunar

  6. Lobules of inferior vermis and hemisphere • 1-tuber…………..inferior semilunar • 2-pyramid………biventral • 3-uvula………….tonsile • 4-nodule………..floculus

  7. Fissures of cerebellum • 1- primary fissure • 2- horizontal fissure • 3- postrolateral fissure

  8. Division of cerebellum • Based on morphology • 1- anterior lobe • 2- middle/posterior lobe • 3-floculonodular

  9. Division of cerebellum • Based on development • 1- Archiocerebellum (lingula + floculonodular). • 2- Paleocerebellum(ant. Lobe – lingula + pyramid and uvula) • 3-neocerebellum( post. Lobe – pyramid and uvula).

  10. Division of cerebellum • Based on physiology • 1- vestibulocerebellum • 2- spinocerebellum • 3-pontocerebellum

  11. Cross section of cerebellum • Gray mater • 1- cortex • 2-deep nuclei (intracrebellar nuclei) • White mater • 1- lamina alba • 2- corpus medullaris

  12. Corpus medullaris • 1- proper fibers ( association and commisural) • 2- projecting fibers (cerebellar peduncles)
