PSYB30H3 Study Guide - Final Guide: Autonomic Nervous System, Unconscious Mind, Sympathetic Nervous System
Document Summary
One way to be healthier and happier is to meditate. The nervous system is made of the central nervous system (cns; brain and spinal cord) and the peripheral nervous system (pns; somatic movements of muscle. And autonomic smooth and cardiac muscle, glands). The autonomic nervous system divides energy for sympathetic (fight or flight situations)/parasympathetic (replenish body: salivation and digestion). Brain is protected by cerebrospinal fluid (csf) that flows through spaces in the brain (ventricle). Researches hypothesize that differences in bodily responses, brain structure, brain activity and biochemical activity are all related to individual differences in personality. Bodily responses: the body"s responses to environment are caused by the autonomic system. The galvanic skin response (gsr) measure skin conductance or how quickly a slight electrical current passes through 2 points on the skin (the faster, the more moisture, the greater arousal). The electromyography (emg) measure muscle activity and estimates electric impulses of muscle during contraction and relaxation.
