  Neurological System Ammad MahmoodMohamed AbdelhalimGUMSA Revision Lectures  Neuroanatomy ã Brain ã Cranial nerves ã Spinal cord  Brain Anatomy ã Massive area  – will try and give you a briefoverview  – not all the detail is included, justenough to give you a rough understanding of thelayout of the brain ã Developmentally the brain can be divided intothe:  – Forebrain  – Midbrain  – Hindbrain  Grey and White Matter ã Grey matter  – Contains the cell bodies of 85% of the body’s neurons  – Located in the cerebral cortex and the basal nuclei ã White matter  – Contains the axons of the neurons, 3 types: ã Association fibers  – interconnect the cortex within onehemisphere ã Commisural fibers  – interconnect hemispheres ã Projection fibers  – link cortex to lower structures(diencephalon, brainstem, cerebellum, spinal cord)  –  form the internal capsule
