Answer: Autonomic nervous system
Step-by-step explanation:
- The autonomic nervous system (ANS) is a division of the peripheral nervous system which is responsible for controlling the involuntary actions in our body.
- The ANS has two divisions- the sympathetic division and the parasympathetic division. It is the sympathetic division of the ANS which is responsible for the flight or fight responses and the parasympathetic for rest and digest responses.
- Whenever we face stressful conditions the sympathetic nerves signal the adrenal gland to release the catecholamines which are epinephrine and norepinephrine which causes several reactions in our body and help us to cope up with stress.
