Expert Solution
Step 1

The Autonomic Nervous System forms a part of the peripheral nervous system. The processes like pulse, breathing, blood pressure and arousal during emotional circumstances are controlled by this system. This system is not under the voluntary control. 

Step 2

The sympathetic and parasympathetic nervous systems are the subdivisions of the Autonomic Nervous system.

When the activation of the sympathetic nervous system takes place , it starts to prepare the body for emergency.On activation, the sympathetic nervous system cause the production of epinephrine from the adrenal glands resulting in the activation of fight or flight response. The blood flow to the muscles increase, there is increase of the heart rate, and other processes etc as a result of fight or flight response.

The emotional regulation works proactively to prevent the threats or stress or control the levels of arousal of emotions at the situations requiring the need of fight or flight response.
