Document Summary
Chapter 10: stress, coping, and health y resistances to the adverse effects of stress may be the key to longevity, as all of the anti- aging genes appear to regulate cell-based stress resistance. Stress y there are three major ways of defining stress: physiological state of the organism (sometimes referred to as strain) cannon was the first physiologist to systematically describe the physiological effects of stress. the sns reacts to stress in two ways: The sympathetic nerves originate in the spinal column (preganglionic nerves) and radiate to the target organs (postganglionic nerves). The preganglionic nerves are cholinergic, that is they secrete the neurotransmitter acetylcholine. The second type of sns response to stress is a little less direct. In the sympathetic/adrenal medulla (sam) system, the sympathetic nerves radiate to the adrenal medualla, which is a small structure lying atop of the kidneys.
