Stress hormone system
During the stress response, the sympathetic nervous system and a number of hormone glands – the hypothalamus, pituitary gland, and adrenal cortex – work together to prepare the body for increased demands. The sympathetic nervous system uses the hormones adrenaline and noradrenaline as messenger substances. Their activity increases breathing and heart rate while improving blood flow to the muscles. During the stress response, the adrenal cortex releases the hormone cortisol. It acts via negative feedback on the hypothalamus and pituitary gland, thereby slowing down further cortisol release. When the stressor subsides and the sympathetic tone decreases, the parasympathetic nervous system can regain the upper hand and bring the organism into a state of rest.
