Quizplus · Accepted Answer

The sympathetic nervous system is responsible for the body's fight or flight response and prepares the body for action in emergency situations, such as perceiving a potential danger like the possibility of a child falling down the stairs. This system causes physiological changes like increased heart rate, blood pressure, and sweating. The parasympathetic nervous system is responsible for calming the body down and returning it to a relaxed state. The somatic nervous system is responsible for voluntary movements, while the central nervous system consists of the brain and spinal cord.
