Document Summary
Stress: stimuli, condition or situation that causes the loss of homeostasis (anything that disturbs homeostasis: action is required to minimize damage, failure to adapt results in the loss of health & development of. Lecture 17: comparative stress physiology disease (the stress response: acute stress: prey & predator, immune response, severe weather, reproduction, chronic stress: forestry, landscape changes, global warming & pollution. Stress response: response of physiological systems to adapt to/avoid the stressor, involves the redistribution of energy usage & increase supply of energy to tissue that requires it. Different hormones require different times so their effects on target tissues can be observed. Catecholamines are fastest & glucocorticoids are much slower. Animal starts to show physiological consequences of the stress response. Cardiovascular tone, immune activation, energy mobilization etc. Catecholamines: 1st wave of stress response extreme rapid acting on all cells : act on g protein coupled receptors, cardiovascular tone, energy mobilization & mental alertness.
