general adaptation syndrome | Developed by Hans Selye, a profile of how organisms respond to stress; the general adaptation syndrome is characterized by three phases: a nonspecific mobilization phase that promotes sympathetic nervous system activity; a resistance phase, during which the organism makes efforts to cope with the threat; and an exhaustion phase, which occurs if the organism fails to overcome the threat and depletes its physiological resources.
