Walter Cannon, a harvard physiologist, first investigated the fight or flight response in 1927.
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).
The Wright brothers' first powered flight on December 17, 1903, lasted for about 12 seconds and covered a distance of 120 feet.
1621 when it was named after the Bursa of Fabricius
Richard Paltauf first described a case of mucormycosis in the middle of the 19th decade (1850s).
Johannes Kepler did that first.
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
blood pressure increases hormones are released
flight or fight and if it is afraid it is going to have a flight instinct
blood pressure increases hormones are released
The first psychological response a person might notice in the alarm phase of the general adaptation syndrome is the body's fight-or-flight response, where adrenaline is released to prepare the body to face the perceived threat or stressor. This can lead to heightened awareness, increased heart rate, and a sense of urgency.
To run. The first thing a horse will do when frightened is to run. If they feel trapped then they will fight by rearing and by kicking. Its called "Fight or flight". Fight or run. A horse will bolt (run) and can squeal. If a horse is really scared, or has fear, there would be little whites in their eyes.
The first rule of Fight Club is: You do not talk about Fight Club
The fight or flight response is primarily associated with the first stage of General Adaptation Syndrome (GAS), known as the alarm reaction stage. This initial response occurs when an individual perceives a threat, triggering the body's immediate physiological reactions, such as increased heart rate and adrenaline release. This prepares the body to either confront or flee from the danger. If the stressor persists, the body may move into the resistance stage, where it attempts to adapt to the ongoing stress.
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.
