Document Summary
Stressor: any physical or psychological event or condition that produces stress. Stress response: the physical and emotional changes associated with stress. Stress: the general physiological and emotional state that accompanies the stress response. Autonomic nervous system: the branch of the nervous system that controls basic body processes; consists of the sympathetic and parasympathetic divisions. Parasympathetic division: a division of the autonomic nervous system that moderates the excitatory effect of the sympathetic division, slowing metabolism and restoring energy supplies. Sympathetic division: a division of the autonomic nervous system that reacts to danger or other challenger by almost instantly accelerating body processes. Norepinephrine: a neurotransmitter released by the sympathetic nervous system onto specific tissues to increase their function during increased activity; when released by the brain, causes arousal; also called noradrenaline. Endocrine system: the system of glands, tissues, and cells that secrete hormones into the bloodstream to influence metabolism and other body processes.
