Document Summary
In the early 1930s hans selye was the first to describe a group of anatomic changes that occurred in rats that were exposed to a variety of different experimental stimuli. He described stress as a state manifested by a specific syndrome of the body developed in a response to any stimuli that made an intense systemic demand on it . Stressors: events or environmental agents responsible for initiating the stress response. Stressors can be endogenous, arising from within the body. The stress response is designed to be an acute response, turned on when necessary. Therefore under normal circumstances the normal responses and the hormones that are released during the response do not persist long enough to cause damage to vital tissues. It is an external or internal stressor that alters homeostasis. Eustress: a positive stress, like a new baby, or a new job. Premenopausal women have lower sns activation in response to stressors(cf men)
