Document Summary
Central nervous system: brain (reading material: chapter 16: pages 406-428; chapter 22: pages 585-586,594) Telencephalon: cerebral hemispheres: the two halves of the brain which are 80% of the brain mass. Longitudinal cerebral (sagital) issure: midline separaion of the two halves: cerebral cortex: outer covering of the cerebral hemispheres, gyri (us=singular): twisters and bumps, elevated ridges, increases surface area, precentral gyrus (motor cortex, postcentral gyrus (sensory cortex) Lobes: frontal, parietal, occipital, temporal, insula: hidden lobe, put ingers in lateral sulcus and pull it apart, deep in lateral sulcus is a cortex containing the insula. The brain uses gray mater for computaion, thinking, memory storage, and more. White mater allows diferent parts of the brain to communicate with each other. Pns: gray mater, located in cerebral cortex, consists of neuron cell bodies, basal nuclei/ganglia: Deep gray mater, receives a large amount of input from cerebral cortex, and ater processing, send it back to cerebral cortex via thalamus.
