Examples include the acceleration of the heartbeat, raising of blood pressure, shrinkage of the pupils of the eyes, and the redirection of blood away from the skin to muscles, brain, and the heart.
The fight or flight response is a physical response; a strong stimulus or emergency causes the release of a chemical called nor-adrenaline (also called norepinephrine)
the thyroid gland
The fight or flight response is the hormone adrenaline so the chances are that at least some of your senses become more alert.
The sympathetic nervous system, more specifically, fight or flight response is mediated through the hypothalamus.
Adrenaline is released during alarm phase of the general adaptation syndrome, when it is necessary to enlist the fight or flight response. This adaptation is so hard-wired in our bodies that simply watching a scary movie can elicit the response, cause the body to release Adrenaline, and bring about all the same physiological changes that are produced if a knife-wielding person attacked you. The same response can occur when you open your electric bill and see that you owe nearly $500, or when a person softly approaches so you didn't hear them coming and they surprise you.
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.

The sympathetic nervous system, more specifically, fight or flight response is mediated through the hypothalamus.
It is caused by the neurohormone called norepinephrine.
This is known as the fight-or-flight response. It includes the release of adrenaline and noradrenaline. The heart rate increases, the pupils dilate, breathing rate increases to prepare the body to be able to survive the immediate stressful situation.
The ALARM response
Adrenaline is released during alarm phase of the general adaptation syndrome, when it is necessary to enlist the fight or flight response. This adaptation is so hard-wired in our bodies that simply watching a scary movie can elicit the response, cause the body to release Adrenaline, and bring about all the same physiological changes that are produced if a knife-wielding person attacked you. The same response can occur when you open your electric bill and see that you owe nearly $500, or when a person softly approaches so you didn't hear them coming and they surprise you.
Epinephrine, adrenaline, and cortisol are hormones that have all been linked to the "flight or fight" response.
