  • Stress
    • Short-term (acute)
      • Sympatho-Medullary Pathway
        • Hypothalamus
          • Sympathetic branch of the autonomic nervous system (ANS)
            • Adrenal Medulla
              • Adrenaline and Noradrenaline
                • Fight or Flight
                  • Increased Glucose
                    • Supprssion of non-essential systems
                      • Parasympathetic branch of the autonomic nervous system (ANS)
                        • Countershock response, returns body to its normal resting state
                      • Including the digestive systems
                    • Glucose is quickly released into the bloodstream
                  • Physical changes caused by adrenaline and noradrenaline
                • Prepares the body for flight or fight response
              • Secretes adrenaline and noradrenaline (hormones)
            • Stimulates the adrenal medulla (inner part of the adrenal gland)
          • Recognises acute stress
    • Long-term (chronic)
      • Pituitary-Adrenal System
        • Hypothalamus
          • Corticotropic Releasing Factor (CRF)
            • Pituitary Gland
              • Adreno-corticotropic hormone (ACTH)
                • Adrenal Cortex
                  • Corticosteroids
                    • Immuno-suppression
                      • Suppression of the body's immune system as a way of conserving energy
                    • Stimulates the liver to release a steady supply of glucose and cuases immuno-supression
                  • Releases corticosteroids (a range of hormones) including cortisol
                • Stimulates the adrenal cortex (the outerpart of the adrenal glands)
              • Releases serveral hormones into the bloodstream
            • Alerts the pituitary gland in the brain
          • Recognises chronic stress
