Document Summary
Unit g: nervous system part 2 - cns, pns, and ans. Emotional brain- primal fear, primal anger (survival emotions: divided into hemispheres. Separated by fissure- longitudinal fissure: central fissure (r l); Side- lateral fissures: make lobes, brain waves, alpha 8-13 hz (cycles per second) Fastest: only during sensory input or extreme mental activity (making a decision, thinking about relaxing, theta 4-7 hz, children. Adults under emotional distress, problem solving: rem (dream) sleep, cns disorders too, delta 1-5 hz. Slowest: only during sleep in adults (dreamless deep sleep) In adults when awake = brain damage: coverings of the brain & spinal cord, cranial meninges, dura mater, outermost (nearest to bone) all the way around brain and spinal cord. Hco3-), wbcs: important- glucose = glycolysis, proteins basic building blocks, lactic acid backed up with krebs and etc pyruvate lactic acid glucose glycolysis. Few leaky capillaries- fluid blood plasma leaks out, plasma in nervous system =
