Nervous System

1. Central Nervous System

   • Humoral regulation is one of the earliest evolutionary mechanisms of vital processes regulation in the body, carried through the body fluids (blood, lymph, tissue fluid) with the help of hormones excreted by cells, organs, tissues. In organisms of highly developed animals and man the humoral regulation is subject to the neural regulation and both of them are integrated in a single system of neurohumoral regulation.
   •    VLF – very low frequency, slow waves. Their duration exceeds 30 sec., the oscillation frequency of 0.04 Hz. This range is associated with an activity of the central nervous system (humoral regulation).   

2. Autonomic Nervous system

   • parasympathetic
     • rest, relaxation   HF – high frequency, fast waves. Their duration is 2,5-6,6 sec., the oscillation frequency – 0,15-0,4 Hz. This range is associated with a parasympathetic activity.   
     • Parasympathetic system is responsible for relaxation, recreation, preservation and accumulation of vital energy.
     • rest, relax
   • sympathetic
     • Fight or flight   LF – low frequency, medium wave. Their duration is 10-30 seconds, the oscillation frequency – 0,04-0,15 Hz. This range is associated with an activity of the sympathetic division.   
     • Sympathetic nervous system is responsible for the mobilization of domestic resources of the body
     • Fight or Flight
   • Enteric
