When a stress response is triggered, it sends signals to two other structures: the pituitary gland, and the adrenal medulla. These short term responses are produced by The Fight or Flight Response via the Sympathomedullary Pathway (SAM). Long term stress is regulated by the Hypothalamic Pituitary-Adrenal (HPA) system.What are some ways that the body reacts to stress?
When we are stressed, we release excitatory neurotransmitters. Your body responds to these hormones by increasing your heart rate, blood pressure, and respiration. More blood is pumped into your muscles, sending more oxygen to your muscles, brain, heart and lungs.
