The parasympathetic nervous system (PSNS) is one of the three divisions of the autonomic nervous system, the others being the sympathetic nervous system and the enteric nervous system. The enteric nervous system is sometimes considered part of the autonomic nervous system, and sometimes considered an independent system. http://downloads.lww.com/wolterskluwer_vitalstream_com/sample-content/9781496347961_Frandsen11e/samples/Frandsen_ch046.pdf
