Lesson 1 - 12: Autonomic Nervous System
Sympathetic and Parasympathetic..... "fight or flight" versus "rest and repair". Separate structures and chemistry. Different nerves. Different locations. Different branching patterns. Different neuro-transmitters. Sympathetic responds to stress... running from a bear. Parasympathetic heals, stores and regenerates/grows. Parasympathetic dominates at night. Balance needed most times. Kind of like tides. Stress stimulates sympathetic - disrupts digestion. Adrenalin rush can cause low blood sugar afterward. During adrenaline rush, mouth becomes dry, pupils dilate, eyesight becomes more acute, nasal glands dry up/arteries constrict, tear glands dry, gastric juice production stops, ditto pancreas, sweat glands dry... but palms, soles of feet fate and neck sweat more. Heart rate increases. Blood to heart increases. Bronchia dilate to take in more oxygen. GI tact tube enlarges to reduce feeling of fulness, sphincters' contract to stop movement. Stored sugar comes out of reserve into the blood. Bile increases. Kidneys decrease output. Blood pressure increases. Bladder gets bigger and urine production turns off. If full, may pee. Spleen contracts and stores blood. Any blood vessel that can contract will contract. Blood is shunted to brain, heart, lungs and muscles. Blood coagulation clotting increases. Fat cells break down, lipids become available. Increased basal metabolism. Krebs cycle increases, more ATP, cellular functions speed up. Mental activity increases. Hair stands on end (like a cat to look bigger). Muscles get stronger, sometimes super human. Reproductive system shuts down. If pregnant, may induce labor.
His talk of having been an adrenaline junky and how we all live on stress and excitement is foreign to me. Seems I'm more laid back than the hippie... go figure... I guess hillbillies just know how to live. 😉
