Most of the adrenaline in the human body is released by the adrenal gland. The adrenal gland is a part of the sympathetic nervous system, a branch of the nervous system that regulates the classic stress response and has numerous roles in other normal body functions. Adrenaline, called epinephrine by scientists in the US, is the major hormone released during the classic stress response (also called the fight-or-flight response), which is why it is often considered a fight-or-flight hormone. It has several actions in the body that make it good at this job: it dilates the pupils to increase the amount of light that enters the eyes, it causes sweating to help dissipate heat, it increases blood flow to the muscles, it increases the heart rate and force of contraction, and it makes glucose available in the blood for use by other organs.
During the fight-or-flight response, your body provides you with energy, reflexes, and strength you may need to respond to the stressor. As past of the fight-or-flight response, your body releses epinephrine formerly called andrealine, is one of the hormones that are released by the body in times of stress. Epinephrine prepares the body for quick action by triggering the changes listed below.
This fundamental physiologic response forms the foundation of modern day stress medicine. The "fight or flight response" is our body's primitive, automatic, inborn response that prepares the body to "fight" or "flee" from perceived attack, harm or threat to our survival.
Adrenaline is the hormone that is normally release when a person is scared. It speeds up your heart rate and dilates your veins so that you are at maximum blood flow and your muscles can get the maximum energy possible as fast as possible. It is design so that in dangerous situations you either have maximum strength for a fight, or you have maximum energy to run as fast and as far as your body can.
blood pressure increases
hormones are released
The ALARM response
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.
The ALARM response
The adrenal medulla is responsible for the fight-or-flight response. It releases a hormonal cascade that results in the secretion of epinephrine and nonrepinephrine.
Walter Cannon, a harvard physiologist, first investigated the fight or flight response in 1927.
The sympathetic nervous system is responsible for the fight of flight response. The the adrenal glands release epinephrine in the fight or flight response, and norepinephrine after the threat ceases.
The fight or flight response is not only experienced by humans. Animals also experience this when danger is near. They either run away, or stand and fight.

It is the old fight or flight response.
