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
First of all it's "response".. And to answer your question, Adrenaline. It may also include how the person was raised. Either they were raised to sty and fight.. Or run away.
The Adrenal Medulla controls the fight-or-flight reaction. :)
Adrenal Medulla
The pineal gland releases melatonin, which regulates sleep/wake cycles. The adrenal glands release epinephrine, which is the fight or flight hormone.
secretes adrenalin, which puts you in fight-or-flight mode.
The thyroid gland controls metabolism.
The adrenal gland excretes adrenalin (epinephrin) which is a hormone that gives sudden bursts of energy to muscles. Used a response to stress. Part of the fight or flight mechanism.
pituitary gland
The hypothalamus controls the pituitary gland.
