Compare and contrast:Sympathetic nervous system and Parasympathetic nervous system

Answer»

Example: 

  • Situation: Suppose you are chased by a dog. 
  • Sympathetic nervous system: Due to the functioning of this system, your heartbeat and palpitation increase. You also start to sweat.
  • Parasympathetic nervous system: When PNS takes over, your heart rate, palpitation, and sweating become normal. You regain a cool and composed state due to the functioning of this system.
