Primary functions: receive/process sensory info, appropriate responses mucles and glands, emotion, memory, cognition and learning. Basic patterns of cns: central cavity, filled with csf, ependymal cell lining, grey matter (cell bodies), external white matter (myelinated tracts) surrounds, cerebral hemisphere/cerebellum outer cortex is grey matter. Protection of cns: skul + vertebral column, meninges: dura mater, arachnoid, pia, csf: flows between subarachnoid space, shielded from periphery by tght junctions between cells of capillary endothelium (blood brain barrier) Anterior circulation: external ad internal carotids, anterior cerebral, posterior communicating branches. Connected at base: circle of willis. Easy stuff, obvs should know this already. The brain: cerebrum the brain you think is the brain. Left and right hemispheres: cerebral cortex is outermost (6 layers of grey matter) Occipital : visual cortex and association areas. Parietal: somatosensory cortex and association areas, interpret vision! Temporal: hearing and equilibriujm, emotion, memory, interpret language and vision.
