Stress: Fight or Flight Response The response was later recognized as the first stage of a general adaptation syndrome that regulates stress responses among vertebrates and other organisms. The onset of a stress response is associated with specific physiological actions in the sympathetic nervous system, primarily caused by release of adrenaline and norepinephrine from the medulla of the adrenal glands. The release is triggered by acetylcholine released from preganglionic sympathetic nerves.

- By its very design, the fight or flight response leads us to fight or to flee—both creating immense amounts of muscle movement and physical exertion. This physical activity effectively metabolizes the stress hormones released as a result of the activation of our fight or flight response. Once the fighting is over, and the threat—which triggered the response—has been eliminated, our body and mind return to a state of calm.
