Our nervous system is organized into two broad anatomical divisions: the central nervous system (consisting of the brain and spinal cord) and the peripheral nervous system (pns). your pns is further organized into two functional divisions. if you tap your knee, the signal to act is carried via your to the muscles in your knee. in contrast, the signals that pass via the are involuntary and act primarily to regulate your body's internal environment. this involuntary nerve system is further organized into three divisions. if you need a sudden burst of energy, your is activated to you act quickly. in contrast, if you are relaxing and conserving energy, then it is your that is primarily in action. the third division is your which control the components of the digestive system.

If you tap your knee, the signal to act is carried via your somatic nervous system to the muscles in your knee. In contrast, the signals that pass via the autonomic nervous system are involuntary and act primarily to regulate your body's internal environment. This involuntary nerve system is further organized into three divisions. If you need a sudden burst of energy, your sympathetic nervous system is activated to help you act quickly. In contrast, if you are relaxing and conserving energy, then it is your parasympathetic nervous system that is primarily in action. The third division is your enteric nervous system which helps control the components of the digestive system.

Explanation:

Peripheral nervous system (PNS) is the nervous system that contains nerves and ganglia outside the central nervous system (CNS). PNS is divided into:
