Three different major ways to describe stress: stress as a physiological state. Classic theories: cannon (1915) was the first physiologist to systematically describe the physiological effects of stress.

Acth stimulates the cortex of adrenal glands to release corticosteroids [glucocorticoids] www. notesolution. com. 1: hans selye expanded on cannon"s conceptions in two ways.
