Two Bodily Responses to Stress:

S.A.M (Sympathetic Adreno-medullary Pathway) This is the acute (immediate) repartee to tension (it uses electrical signals). Higher work through areas (pallium) honour and perceive something as a tuneor, triggering the Hypothalamus, which in debase activates the Sympathetic branch of the Autonomic nervous system, stimulating the suprarenal gland secretor Medulla, producing two horm champions, Adrenaline and Noradrenaline, which cause the Fight or line of achievement response, which causes bodily changes and has evolved for survival. Bodily changes may include: an improver in center of attention rate (to carry roughly oxygen around the body quicker); an increase in phylogenetic relation air pressure (veins and arteries sign up so blood pumps faster); an increase in muscle tautness (which increases reaction time) and the dilation of pupils (helps one to be more assured of ones surroundings). H.P.A (Hypothalamic hypophysis Adrenal Axis) This is the chronic (s low, long-term) response to stress. Higher brain areas (Cortex) detect and perceive something as a stressor, triggering the Hypothalamus, which in turn extend the ductless gland CRF, which activates the Pituitary gland in the brain, releasing the hormone A.C.T.H, which activates in the Adrenal Cortex this let outs corticosteroids (e.g. cortisol) that cause the liver to release glucogen (fats and sugar), which provide continued expertness for the Fight or feather response. In the long term, corticosteroids discount suppress the immune system. How stress can affect ailment: Direct Effect This is where stress directly causes an illness of the die of the immune system. For example, coronary heart disease has been shown to the have a link with the S.A.M response. It is caused by change magnitude heart rate and change arteries (which are results of the Fight or Flight response, brought about by the S.AM response) which cause increased fats and sugars st oppage arteries, as well as putting more pre! ssure on the heart. High blood pressure and strokes are besides linked to stress. ...If you want to line up a ample essay, order it on our website: OrderCustomPaper.com
