Write a short note.
Autonomic Nervous System
उत्तर
Peripheral Nervous System consists of the Somatic Nervous System and the Autonomic Nervous System. Autonomic Nervous System is further divided into the Sympathetic and Parasympathetic Nervous System. Autonomic Nervous System controls internal activities of human body including heart rate, breathing, digestion, disposal of waste products and toxins.
Sympathetic nervous system prepares our body to face stressful and threatening situations. It prepares us for the "flight or fight" reaction. For example, when you are chased by a dog, that time your heartbeat, palpitation increases and you start sweating. The job of the system is just opposite to its name.
Parasympathetic Nervous System takes over when the situation becomes normal. When this system takes over, your heart rate, palpitation, and sweating become normal. We regain our cool and composed state. It directs our body to store energy for emergencies.
