Question

What triggers the fight or flight response?

Answer 1

Hormones of Flight or fight:

1. Adrenaline or epinephrine and noradrenaline or norepinephrine are the two hormones secreted by the adrenal medulla region of the adrenal gland.
2. These two hormones are also called catecholamines which are released under stress conditions.
3. The release of two hormones leads to increased heartbeats, sweating, and pupillary dilation.
4. They also stimulate the breakdown of glycogen resulting in increased blood glucose levels.

Flight or fight response:

1. It is the response generated to mark the presence of an acute threat to survival by showing some physical changes, including nervous and endocrine changes.
2. The fight-or-flight response is characterized by an increased heart rate, anxiety, increased blood glucose concentrations, and an increased rate of respiration.
