guajiro [1.7K]

Answer:

C) It has a long preganglionic fibers

Explanation:

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

  1. somatic (voluntary) nervous system-controls the movements of the skeletal muscles
  2. autonomic (involuntary) nervous system-controls the smooth muscles and glands and thus it is the regulator of the major body functions. It is subdivided into tree groups:
  • sympathetic ("fight and flight") system-responsible for stressful and active situations (but also in normal conditions);contains short preganglionic fibers and long postganglionic fibers.
  • parasympathetic ("rest and digest") system-opposite to sympathetic, responsible for the maintenance of body's activities at rest.
  • enteric nervous system-controls the function of the gastrointestinal tract.
