The Sympathetic Nervous System Affects The Human Body

•The sympathetic nervous system is turned on by emotional and physical stressors as such as depression or exercise. The sympathetic nervous system Is in control of the fight or flight response of the body which occurs when the sympathetic fibers that go to the adrenal medulla secrete acetylcholine, this results in the secretion of epinephrine and norepinephrine. This makes the heart beat faster, pupils to dilate , goose bumps, sweating, saliva production reduced (dry mouth), peristalsis reduced and an increase in blood pressure.

•The parasympathetic nervous system counters the sympathetic effects and help reduces heart rate when a stressful situation occurs and passes. Most of the time our body is in parasympathetic nervous system control
