   Glucocorticoids have massive and far-reaching effects on the body and brain, including increases in blood pressure, increased glucose circulation, decreased reproductive axis output, complex effects on immune functions and various other effects (step 5 in Figure 12.12). In addition to glucocorticoids, the adrenal gland also produces epinephrine and various other hormones from cells in the ...

   May 7, 2024 · A stressful situation, whether environmental or psychological, can activate a cascade of stress hormones that produce physiological changes. Activating the sympathetic nervous system in this manner triggers an acute stress response called the fight-or-flight response.

   Apr 5, 2023 · Stress can affect several parts of the body, including the head, heart, stomach, back, and shoulders. Stress triggers the body’s “fight-or-flight” response, which causes a surge of hormones like cortisol and adrenaline.

   Oct 17, 2020 · Dysregulation of the stress system (hyper- or hypo-activation) in association with potent and/or chronic stress can markedly disrupt the body homeostasis leading to a state of cacostasis or allostasis, with a spectrum of clinical manifestations.

   Oct 28, 2022 · Because metabolic stressors such as starvation induce high glucocorticoid levels, it’s been suggested that these hormones might help prepare the fetus for the environment it will be born into. Tough, stressful environments push fetuses to develop stress-sensitive “thrifty” metabolisms that store fat easily.

   This integration of information from the stressor itself may result in a rapid activation of the Sympathetic-Adreno-Medullar (SAM) axis and the Hypothalamus-Pituitary-Adrenal (HPA) axis, the two major components involved in the stress response.

   Which organs trigger a stress response?

   • Other important structures for triggering the stress response are the circumventricular organs (i.e., the median preoptic nucleus, the subfornical organ (SFO) and the organum vasculosum of the lamina terminalis), that respond to perturbations in fluid and send projections to other integrative brain regions.

   What is a stress response?

   • The stress response is adaptive to prepare the body to handle the challenges presented by an internal or external environmental challenge, such as stressors. For example, the body's physiological responses to trauma and invasive surgery serve to attenuate further tissue damage.

   How does stress affect the body?

   • During this recovery phase, the body remains alert until the stressful event is no longer triggering. However, if the stressful event persists for extended periods, the body adapts to cope with higher stress levels. The body continues to secrete stress hormones, which maintain the body's elevated physical response to stress.

   How is a stress response mediated?

   • A stress response is mediated through a complex interplay of nervous, endocrine, and immune mechanisms, activating the sympathetic-adreno-medullar (SAM) axis, the hypothalamic-pituitary-adrenal (HPA) axis, and the immune system.

   What causes a stress response?

   • Last Update: May 7, 2024. Any physical or psychological stimuli that disrupt homeostasis result in a stress response. The stimuli are called stressors, and physiological and behavioral changes in response to exposure to stressors constitute the stress response.

   How does the brain respond to stress?

   • The stress response to physical and/or psychological stressors, organized by the previously described brain circuitry, involves a rapid physiological adaptation mediated mainly by catecholamines (de Kloet et al., 2005a; Joëls and Baram, 2009; Tank and Lee Wong, 2015).

   Apr 3, 2024 · Over time, repeated activation of the stress response takes a toll on the body. Research suggests that chronic stress contributes to high blood pressure, promotes the formation of artery-clogging deposits, and causes brain changes that may contribute to anxiety, depression, and addiction.
