When faced with imminent physical danger, thehuman body’s sympathetic nervous system triggers our "fight-or-flight" response. The sympathetic nervous system is a normally harmonized network of brain structures,nervesandhormonesthat, if thrown off balance, can result in serious complications. What is...
Your sympathetic nervous system is responsible for your “fight or flight” response. It’s activated when your brain senses that you’re in a stressful situation. The sympathetic nervous system function includes: Dilating (enlarging) your pupils, the dark hole in the center of your eye, so it...
Fight or Flight To produce the fight-or-flight response, thehypothalamusactivates two systems: the sympathetic nervous system and the adrenal-cortical system. The sympathetic nervous system uses nerve pathways to initiate reactions in the body, and the adrenal-cortical system uses the bloodstream. The...

Our sympathetic nervous system plays a vital role in helping us respond to dangerous situations. Here's how 'fight or flight' works.
How does fight or flight affect the body? Upon perceiving a threat, your stress response gets triggered by two components of your body: your sympathetic nervous system and your hypothalamic-pituitary-adrenal axis, or HPA axis for short. Together, your HPA axis and your sympathetic nervous system...
You may have heard of the “fight or flight” response—an evolutionary system that allows us to enter a survival state in the presence of physical or psychological threats. Your fight-or-flight mode is activated by the sympathetic nervous system. It’s meant to force you into action in ord...

When you experience acute panic, your adrenal glands dump cortisol and adrenaline into our system, causing your blood pressure to surge and your heart to race. This energy surge enables you to (hopefully) escape from the bear’s attack. Without this “fight or flight” response mechanism, you...
The ‘fight or flight’ response describes the most immediate changes in physiological and behavioral state within an animal subsequent to stress exposure. These changes are mediated by thecentral nervous system(CNS), although this component of a stress response is often attributed to the actions of...
