    The ANS (Autonomous nervous system) is divided to PNS (parasympathetic nervous system) and SNS (sympathetic nervous system).


    The PNS maintains homeostasis and digestive response. The SNS involves fight and flight response. The SNS releases adrenaline. PNS do not involve any secretion of adrenal gland. The PNS relaxes the muscular system, The SNS allows muscles contraction. The PNS decreases heart rate. The SNS increases heart rate.
