Muscles, Nerves and Hormones
  1. The 'Fight or Flight' Response
    1. Physiological Changes
      1. Pupils Dilate
        1. Heart rate and BP increase
          1. Blood glucose levels increase
            1. Metabolic rate increases
              1. Endorphins are released
                1. Sweat production increases
              2. Co-ordination of the Physiological Changes
                1. The cerebral understanding of a threat activates the hypothalamus
                  1. Stimulates increased activity in the sympathetic nervous system and triggers the release of adrenaline from the adrenal medulla into the blood.
                  2. The hypothalamus releases CRF into the pituitary gland stimulating the release of ACTH.
                    1. This then stimulates the release of cortisols from the adrenal cortex
