Presentation Transcript

  1. Optic chiasm midbrain (cerebral peduncles) pons pyramids Medulla oblengata

  2. Superior colleculus Inferior colleculus Cerebellar peduncle Vistebular area

  3. pons midbrain medulla

  4. Anterior cerebral Middle cerebral Internal Carotid Artery Posterior cerebral artery Superior cerebellar artery Pontine arteries Labyrinthine artery Basilar Artery Anterior inferior cerebellar artery Anterior spinal artery Posterior inferior cerebellar artery vertebral arteries

  5. * Identify ? • Basilar Artery • List its branches ? • Pontine • Labyrinthine • Anterior inferior cerebellar • Superior cerebellar • Posterior cerebral • * Identify ? • vertebral artery: • List its branches ? • Meningeal branches • Posterior spinal • Anterior spinal • Posterior inferior cerebellar • Medullary

  6. supply all the medial surface of the cerebral till parieto-occipital sulcus. + and 1 inch of lateral surface Anterior cerebral artery :

  7. supply entire lateral surfaces of cortex except the 1 inch and occipital pole . Middle cerebral artery :

  8. Supply occipital pole, and inferolateral surface of hemisphere . posterior cerebral artery :

  9. third ventricle Coroidplexues of third ventricle Cerebral aqueduct Fourth ventricle

  10. Cingulategyrus Septum pellucidum Corpus callosum fornix Coroidplexues of third ventricles Superior colliculus And inferior colliculus Optic chiasma Pituitary Mammillary body

  11. Corpus callosum (splenium ,body, genu, rostrum). fornix What type of fiber ? Commissural fibers, Connect corresponding regions of the two hemispheres.

  12. Corpus callosum : body splenium genu rostrum

  13. Septum pellucidum fornix Corpus callosum Coroidplexues of third ventricles Cerebral aqueduct Fourth ventricle third ventricle
