Stress management encompasses techniques intended to equip a person with effective coping mechanisms for dealing with psychological stress, with stress defined as a person's physiological response to an internal or external stimulus that triggers the fight-or-flight response. Stress management is effective when a person uses strategies to cope ...
A stressor is a chemical or biological agent, environmental condition, external stimulus or an event seen as causing stress to an organism. [1] Psychologically speaking, a stressor can be events or environments that individuals might consider demanding, challenging, and/or threatening individual safety.
They argue that this is due to the underlying physiological changes that the rodent goes through in response to stress. For instance, the changes that occur to the hypothalamic-pituitary-adrenal (HPA) hormonal axis is directly related to the changes in social behaviour. Social avoidance is another consequence of stress that can be seen in rodents.
Stress (biology), an organism's response to a stressor such as an environmental condition; Stress (mechanics), the internal forces that neighboring particles of a continuous material exert on each other; Oxidative stress, an imbalance of free radicals; Psychological stress, a feeling of strain and pressure Occupational stress, stress related to ...
Allostatic load is not unique to humans and may be used to evaluate the physiological effects of chronic or frequent stress in non-human primates as well. [14] The rat cumulative allostatic load measure (rCALM) is a marker for allostatic load in rodents .
The fight-or-flight or the fight-flight-freeze-or-fawn [1] (also called hyperarousal or the acute stress response) is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival. [2] It was first described by Walter Bradford Cannon in 1915.
Skeletal muscles are sensitive to physiological stress, as exercise can impair ER homeostasis. This causes the expression of ER chaperones to be induced by the UPR in response to the exercise-induced ER stress. Muscular contraction during exercise causes calcium to be released from the sarcoplasmic reticulum (SR), a specialized ER network in ...
Cellular stress response is the wide range of molecular changes that cells undergo in response to environmental stressors, including extremes of temperature, exposure to toxins, and mechanical damage. Cellular stress responses can also be caused by some viral infections. [1]
