Walter Cannon, a harvard physiologist, first investigated the fight or flight response in 1927.
Walter Cannon
The sympathetic nervous system. The hypothalamus, in close association with the limbic system of the brain. The "fight or flight" response is the term used for the activation of the sympathetic nervous system. The two main chemicals invoved here are the neurotransmitter "norepinephrine" (noradrenaline) and the hormone "epinephrine" (adrenaline). Noradrenaline is produced in the neurones and is secreted at the synapse to exert its "sympathetic" activity on various organs throughout the body. The nervous system is also responsible for eliciting epinephrine production from the adrenal medulla (a part of the suprarenal glands situtated on the top of each kidney).

Richard Paltauf first described a case of mucormycosis in the middle of the 19th decade (1850s).
Neurofibromatosis type 1 (NF1) was first described in 1882 by the German pathologist Von Recklinghausen. Neurofibromatosis type 2 (NF2) was first described in 1820 by the Scottish surgeon JH Wishart.
It was first described by Walter Bradford Cannon.
A horse has either a flight or fight response. The horse with either run away from what is scaring it, or it will try to fight it.

You might have heard of the fight or flight response in animals. Some animals like bears have the fight instinct, when something scares them they will stand and fight whatever it is and only run if they know they can't win. Horses have the flight instinct, if something scares them they will choose to run first and only fight if they have no other option

flight or fight and if it is afraid it is going to have a flight instinct

Horses are what is called a 'flight or fight' animal. When in a dangerous situation his first choice will be to run or 'flight'. When flight is not an option for whatever reason he will have no choice but to fight. I don't know about you but I don't want to fight with an animal that is 10x bigger than myself.
Horses are prey animals, there instincts are flight and then fight. So they first will flee from the situation and then if that doesnt work they fight.
adreno-cortical. in sync with most systems in your body especially neurological and vasculature. the threshold to whether the fight or flight response is induced is regulated by the brain and perception of a threat. if the a threat is perceived to be real or serious enough to cause the F O F response the kidney release epinephrine, aka adrenaline and the most body system become involved and then you either fight or run based on your brains decision multiple systems are involved along the way this is eblodge's answer When the hypothalamus tells the sympathetic nervous system to kick into gear, the overall effect is that the body speeds up, tenses up and becomes generally very ale
the immediate reaction to a stressor. In the initial phase of stress, humans exhibit a "fight or flight" response, which prepares the body for physical activity
