Document Summary

Identify the major regions of the brain and their primary function(s) Identify the protective covering of the brain and its components. Identify the major blood vessels supplying the cerebral cortex and their regional distribution: describe the ventricular system and circulation of csf. The brain: weighs 3 pounds (2% body weight) The integration centre of the central nervous system. 20% of body energy use everyday energy intensive: wattage of an led/cfl bulb. Lobes of the brain cerebrum has four basic lobes (p,f,o,t) on midterm. Major parts of the brain cerebrum has all the gyri diencephalon all the parts that have thalamus in them brainstem contains mid brain, pons, medulla cerebellum. Cerebrospinal fluid (csf: csf produced by choroid plexus located in each of four cavities (ventricles) of the brain, network of blood capillaries expendmal cells - neuroglia cells specialized support cell responsible for. Csf if hyperactive you create too much csf and this increases pressure.
