The fight or flight structuring within the human body, what is it really comprised of?
Fight and flight reaction in human body is brought about by the activation of the sympathetic nervous system. The sympathetic drive causes release of adrenaline (epinephrine) from the adrenal medulla and noradrenaline from sympathetic nerve endings. The result is an increase in the heart rate and blood pressure, decreased salivation, dilatation of pupils and increase in the blood level of glucose etc.
The aim of the response is to prepare the body to provide with blood to the important organs (muscles to give power, brain to plan) to fight or run. Dilated pupils makes the field of vision more broader. Diversion of blood from the skin reduces bleeding during the response even if injured.
This response was an important response for survival evolutionarily but currently the use of the response is limited to conflicts (e.g. - a fight between two kids to battle field)and sports.
The emergency hormone Epinephrine (Adrenaline or Adrenalin) make the fight-flight (stress) response in human body.Chemically it is amino acid derivatives.
It is secreted for meeting emergency as in injury, pain, emotional stress, fear, anger, grief, fall in blood sugar and pressure.
Adrenaline increases blood supply in the body by constriction of spleen for pouring reserve blood and constriction of arterioles of skin and abdominal organs.

What if your prayers are not answered? Do you continue to pray or fight with God?

I don't think so. I believe that the sub-conscious mind already knows there is no god.The flight and fight mechanism is the driving force behind the need for a god, but the mind already knows it is a self preservation mechanism the conscious mind sets up to cope with the fear of dying.That is why...

Confronted with negativity should you FIGHT or FLIGHT?I always wondered how people should react on certain negative situations. They say it's the attitude that counts and defines the person. But still, should one FIGHT or FLIGHT?
