BRAIN Cognition,Pain perception Wakefulness EYES Pupils, Tears MOUTH& LUNGS Saliva, air passages HEART & BLOOD Rate of heartbeat Blood pressure Blood clotting LIVER, DIGESTION Release of glycogen General maintenance STOMACH Digestive functions Secretions BLADDER Release of urine ADRENAL GLANDS Hormone output GROWTH & SEX ORGANS.
PARASYMPATHETIC SYSTEM normal function (REST & DIGEST) activated by: end of stress cycle or drugs.
Normal thought activity Normal pain perception Longer sleep cycles Contracted pupils Increased salivation Sweat on exertion Bronchi constricted Normal heartbeat: slower Blood pressure normal Blood clotting reduced Digestion normal & relaxed Maintenance of metabolic functions Elimination of toxins Storage of vitamins enzymes Normal digestion of food Normal output of digestive juices Healthy appetite Bladder contraction Normal release of urine Replacement of stress hormones Normal growth & reproduction Regular menstruation Normal bone development & puberty
SYMPATHETIC SYSTEM emergency : (FIGHT AND FLIGHT) activated by: stress reactions and drugs
Increased cognition Dulled pain perception Wakefulness, also at night Dilated pupils Stimulated tear glands, crying Dry mouth, change in speech Increased sweating Dilated bronchi: easier breathing Rapid, violent heartbeat Rise in blood pressure Increased blood clotting Release of stored blood sugar Slow or poor digestion Inhibited liver function Inhibited metabolism of toxins Increased release of stomach acid Poor digestion of stomach contents Loss of appetite, tense stomach Inhibits bladder contraction Inhibits urination Increases output of adrenaline, noradrenaline & cortisol. Inhibits reproductive processes Inhibits growth & onset of puberty
