Literature Review Of Stress
3 Review of literature
3.1. Stress Model and stressor The term stress typically refers to an internal or external (environmental) event that disrupts normal homeostasis. Stressful events always evoke an extensive multi-system and highly integrative physiological response (Kopin et al, 1995 and Goldstein et al, 2007). There exist sex- and age-dependent variations among individuals in response to various stressors and other exogenous stimuli as determined using a wide range of biochemical and physiological endpoints (Smith and Vale et al, 2006). Stress-induced events are complex phenomena involves a galaxy of factors. Laboratory animals have been indispensable in their roles as models in the study of stress, and consequently explore the understanding of what stress is about. A large body of literature has centered on examining the effects of acute and chronic stress. The stress response following a stressor includes the activation of the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal (HPA) axis. The SNS is responsible for the acute stress response, involving the release of catecholamines (epinephrine and norephinephrine) within seconds of the onset of the stressor. The HPA axis is responsible for the chronic stress response, within several minutes of stressor onset involving the release of glucocorticoids. It is found that the glucocorticoid secreted in humans is cortisol and in rodents corticosterone

979 Words | 4 PagesOften called the fight or flight reflex, stress has been known to save people’s lives, whether it be on a battlefield or some dangerous situation back home.

When we go too long without a sharp stimulating response, the body loses its ability to handle stress properly (Tom Scheve, 2009). Somewhere between too much, and too little stress can actually be good for you, helping you perform under pressure. It is when someone cannot turn off that fight or flight feeling that it begins to show its negative effects.

To quote a definition: “Stress is an adaptive response to an external situation that results in physical, psychological and / or behavioural deviations for organizational participants” (Luthans, 1998). Stress has generally been viewed as a set of neurological and physiological reactions that serves an adaptive function (Franken, 1994). Traditionally, stress research has been oriented toward studies involving the body's reaction to stress and the cognitive processes that influence the perception of stress. However, social perspectives of the stress response have noted that different people experiencing similar life conditions are not necessarily affected in the same manner (Pearlin, 1982).

However re-exposure has proven to be more enigmatic or difficult to reverse. Conrad et al (1999) stated that severe or prolonged exposure to stressors is harmful, brief or moderate stressors actually enhance neural function. Various behavioral studies focusing on the memory functions of the hippocampus have demonstrated that moderate stress enhances memory performance but severe stress causes adaptive plasticity and impairs memory. Prolonged stress produces interaction between local neurotransmitters and hormones leading to structural and functional damage causing suppression of neurogenesis.
