Answer:
sympathetic , parasympathetic
Explanation:
The autonomic nervous system have primarily two divisions in the body. One is the sympathetic nervous system division and the other is the parasympathetic nervous system division.
The sympathetic division of the nervous system activates what is often called as the flight response or flight. It operates through a series of neurons that are interconnected to each other. the prolonged activation of the sympathetic division can obtain the release of adrenaline from adrenal medulla. Thus it prepares the body for any action.
Where as the parasympathetic division of the nervous system lowers the adrenaline rush in the body and the excitation effect of the sympathetic part and restores the body's energy supplies.
