   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 ...

   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 28, 2022 · The Stress Response. The stress response weaves together three of the brain’s parallel communication systems, coordinating the activity of voluntary and involuntary nervous systems, muscles, and metabolism to achieve one defensive goal. Messages sent to muscles through the somatic (voluntary) nervous system prime the body to fight or run from ...

   Apr 3, 2024 · Pulse rate and blood pressure go up. The person undergoing these changes also starts to breathe more rapidly. Small airways in the lungs open wide. This way, the lungs can take in as much oxygen as possible with each breath. Extra oxygen is sent to the brain, increasing alertness.

   How does the stress system work?

   • The stress system receives and integrates a great diversity of neurosensory (i.e. visual, auditory, somatosensory, nociceptive, and visceral), blood-borne, and limbic signals which arrive at the various stress system centers/stations through distinct pathways.

   How does the body respond to long-term stress?

   • The body responds in different ways to short-term stress and long-term stress following a pattern known as the general adaptation syndrome (GAS). Stage one of GAS is called the alarm reaction. This is short-term stress, the fight-or-flight response, mediated by the hormones epinephrine and norepinephrine from the adrenal medulla.

   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.

   Moreover, cortisol influences metabolism, promoting the breakdown of fat stores for energy and conserving protein by inhibiting protein synthesis. This metabolic shift helps to preserve essential tissues and organs during prolonged stress, ensuring the body’s survival over an extended period.
