Well the nervous system divides into the central nervous system (CNS) (brain and spinal cord) and the peripheral nervous system (PNS) (everything else). From there, the CNS divides into the autonomic (ANS) (reflex functions) and the somatic (SNS) (voluntary movement) nervous systems. The ANS subdivides into the sympathetic (SANS) (fight or flight) and parasympathetic (PSNS) (rest and digest) nervous systems. Not sure exactly what the question is referring to, but this is a basic layout of all of the main nervous systems.
