It is caused by the neurohormone called norepinephrine.
The flight or fight response causes your body to be filled with adrenaline. There are also other stress chemicals present.
The fight or flight response is triggered by the release of stress hormones like adrenaline and cortisol in response to a perceived threat or danger. This response prepares the body to either confront the threat (fight) or escape from it (flight) in order to ensure survival.
blood pressure increases hormones are released
Yep! The sympathetic nervous system causes both vasoconstriction & vasodilation. During "fight or flight" you need more O2/blood delivered to your skeletal muscles. The SNS causes vasodilation in skeletal muscles. The other organs, of the body (like digestive organs) are not needed for "fight or flight" survival. The SNS causes vasoconstriction in these organs.
During a fight or flight response, the release of stress hormones like adrenaline (epinephrine) triggers an increase in heart rate. This physiological response is designed to prepare the body for immediate action by supplying more oxygen and nutrients to the muscles and brain.
The sympathetic nervous system originates in the spinal cord and its main function is to activate the physiological changes that occur during the fight-or-flight response.
Indigestion often accompanies an emotional upset, because the part of the nervous system involved in the so-called "fight-or-flight" response also affects the digestive tract. People diagnosed with anxiety or somatoform disorders frequently.
No, it slows so you can conserve your energy.
Yes, dogs can sometimes poop when they are scared due to a physiological response called the "flight or fight" response. This can cause their digestive system to speed up and result in them needing to go to the bathroom.
During a sympathetic response, your pupils will dilate to allow more light to enter the eye, helping you to see better in a fight or flight situation. This response is driven by the release of adrenaline and is part of the body's automatic response to stress or danger.
I don't think there is because fight or flight is response action the body makes when in a dangerous situation. Stand and fight or flight RUN.
