Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What part of the nervous system is responsible for restoring the body back to normal functioning after arousal?
A
Central nervous system
B
Sympathetic nervous system
C
Parasympathetic nervous system
D
Somatic nervous system
Explanation: 

Detailed explanation-1: -Your parasympathetic nervous system is a network of nerves that relaxes your body after periods of stress or danger. It also helps run life-sustaining processes, like digestion, during times when you feel safe and relaxed.

Detailed explanation-2: -The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal.

Detailed explanation-3: -When the parasympathetic nervous system (PSNS) is activated, it slows our heart and breathing rates, lowers blood pressure and promotes digestion. Our body enters a state of relaxation, and this relaxation breeds recovery.

Detailed explanation-4: -The brain is what controls all the body’s functions. The spinal cord runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part. This network of nerves relays messages back and forth from the brain to different parts of the body.

Detailed explanation-5: -The parasympathetic nervous system predominates in quiet “rest and digest” conditions while the sympathetic nervous system drives the “fight or flight” response in stressful situations. The main purpose of the PNS is to conserve energy to be used later and to regulate bodily functions like digestion and urination.
