Stress, whether physiological, biological or psychological, is an organism's response to a stressor such as an environmental condition. [ 1 ] When stressed by stimuli that alter an organism's environment, multiple systems respond across the body. [ 2 ] In humans and most mammals, the autonomic nervous system and hypothalamic-pituitary-adrenal ...
Dec 1, 2018 · The term "stress" is used to describe important phenomena at multiple levels of biological organization, but finding a general and rigorous definition of the concept has proven challenging. Current models in the behavioral literature emphasize the cognitive aspects of stress, which is said to occur when threats to the organism are perceived as uncontrollable and/or unpredictable.

Oct 17, 2020 · Stress constitutes a state of threatened homeostasis triggered by intrinsic or extrinsic adverse forces (stressors) and is counteracted by an intricate repertoire of physiologic and behavioral responses aiming to maintain/reestablish the optimal body equilibrium (eustasis). The adaptive stress response depends upon a highly interconnected neuroendocrine, cellular, and molecular infrastructure ...

Mar 31, 2022 · The term stress was widely popularized in its biological connotation in 1936 by Hans Selye, who defined it as “the non-specific response of the body to any demand for change” [1]. Stress was originally understood to be a collection of peripheral symptoms that accompany a variety of chronic illnesses affecting different parts of the body.
Researchers have had a difficult time agreeing on an acceptable definition of stress. Some have conceptualized stress as a demanding or threatening event or situation (e.g., a high-stress job, overcrowding, and long commutes to work), however, for the purpose of this course, we will describe stress as a response to environmental conditions.
