Nervous system: divisions: central (a) brain, b) spinal cord, peripheral (a) somatic (voluntary), b) autonomic (involuntary) sympathetic (arousing), parasympathetic (calming)) 20% of total resting oxygen utilized by brain. Major left hemisphere landmarks: central sulcus, sylvian fissure. Major landmarks: frontal lobe, parietal lobe, occipital lobe, temporal lobe, cerebellum. Primary areas: primary motor area, primary somato-sensory area, primary auditory area, primary visual area. The outermost layer of fray matter making up the superficial aspect of the. Meninges: three membrane layers: dura mater (outer), arachnoid (intermediary), pia mater (inner). Produced in brain ventricles (4 ventricles are present in the brain) Note: if csf reabsorption is blocked: accumulation occurs causes hydrocephalus ( water in brain ), treated surgically with drainage tubes. Involved in: impulse control, judgment, motor function, problem solving, and socialization. Assists in planning, coordinating, controlling, and executing behaviour.
