Physiological stress represents a wide range of physical responses that occur as a direct effect of a stressor causing an upset in the homeostasis of the body. Upon immediate disruption of either psychological or physical equilibrium the body responds by stimulating the nervous, endocrine, and immune systems. The reaction of these systems ...
Real or perceived threat in the environment elicits stress response in animals, which disrupts internal homeostasis. [2] Physiological changes cause behavioural responses in animals, including: impairment of response inhibition and lack of motivation, [3] as well as changes in social, sexual, [4] [5] aggression [6] and nurture [7] [8] behaviour ...
Traumatic events or any type of shock to the body can cause an acute stress response disorder (ASD). The extent to which one experiences ASD depends on the extent of the shock. If the shock was pushed past a certain extreme after a particular period in time ASD can develop into what is commonly known as Post-traumatic stress disorder (PTSD). [11]
Allostatic load is the accumulation of stressors and maladaptive responses that may result in an extreme state, where the stress response does not terminate. [ 26 ] The long-term impact of childhood adversity (e.g., abuse, neglect) has been shown to have lasting effects, including the increased risk for allostatic load in adulthood. [ 27 ]
Chronic stress is the physiological or psychological response induced by a long-term internal or external stressor. [1] The stressor, either physically present or recollected, will produce the same effect and trigger a chronic stress response. [ 1 ]
Defense physiology is a term used to refer to the symphony of body function changes which occur in response to a stress or threat.. When the body executes the "fight-or-flight" reaction or stress response, the nervous system initiates, coordinates and directs specific changes in how the body is functioning, preparing the body to deal with the threat. [1]
Chronic stress is the response to emotional pressure suffered for a prolonged period of time in which an individual perceives they have little or no control. [18] When chronic stress is experienced, the body is in a state of continuous physiological arousal. [ 19 ]
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]
