Document Summary

Best way to think of our physiologies is as a package of potentialities for personality. Nervous system made up of: central nervous system (cns):include brain and spinal cord, peripheral nervous system (pns): includes. Somatic nervous system: controls movements of muscles. Autonomic nervous system: regulates smooth muscle, cardiac muscle, and glands. Sympathetic division: mobilizes energy (fight or flight) Parasympathetic division: supports systems that replenish the body s energy store. Brain protected by cerebrospinal fluid (csf) that cushions brain, and flows through spaces in the brain called ventricles. Researches hypothesize differences in bodily responses, brain structure, brain activity and biochemical activity are all related to individual differences in personality. It is the autonomic nervous system that responses to arousing events in the environment: when aroused the sympathetic division responds by increasing heart rate, blood pressure, blood flow to extremities, respiration, sweating and muscle activity. Sweating measured by galvanic skin response (gsr) skin conductance test.
