visceral system

The idea is that both 'somato-visceral' and 'viscero-somatic' connections exist, and manipulation of the somatic system can affect the visceral system (and vice-versa).

Proponents of visceral osteopathy state that the visceral systems (the internal organs: digestive tract, respiratory system, etc.) rely on the interconnection synchronicity between the motion of all the organs and structures of the body, and that at optimal health this harmonious relationship remains stable despite the body's endless varieties of motion.
