Explanation:

PNS (peripheral nervous system) is one of the two branches of nervous system (the second being CNS that includes brain and spinal cord) that connects the CNS (central nervous system) to rest of the body parts (like different organs of body).

PNS is further divided into two branches-

1) Parasympathetic nervous system (controls the body at rest and homeostasis of body, called "rest and digest" function).

2) Sympathetic nervous system (controls the response of body to situations of threat and produces e "fight or flight" response).
