The perivascular plexus or meridian are identic structures. The Chinese foundation research for acupuncture science has found out, that a meridian is a real existing structure of our body, called the perivascular plexus.
The perivascular plexus or vascular nerve cord, which is identic to the meridian, is formed in the same way, like the Chinese medicine describes in its meridian science since thousands of years, here as an example the gall bladder meridian.
The perivascular plexus are the fibres of the sympathetic nerve (part of the vegetative, nearly not steerable by will) nervous system, which are coating the arterial vessels, up into the organs and the periphery. This means, that our whole organism is connected by a network of vegetative nervous fibres.
Central connections of the perivascular plexus or meridian
The vegetative nervous system surely is the oldest part of our nervous system. It is unknown until today, how the meridians are connected in the brain. I am convinced, that the central perception of the information flow of the vegetative nervous system and its interaction takes place in the until today still quite mysterious limbic system (as one of the developmentally oldest brain areas).
Functional circuit science of the Chinese medicine
The vertebrae, segments and meridians are connected among each other after a very certain system in so-called functional circuits (Picture).
To a functional circuit there always belong a store- and a hollow organ as well as a body orifice. All body orifices are to be found at the cervical spine.
The damage at one part of a functional circuit produces at the same time a disturbance in other parts of the same functional circuit.
There exist five different functional circuits.
In addition the functional circuits are connected among each other.
The functional circuit heart (Th2 SMT®)/ small intestine (Th12 SMT®)/ tongue and eyes (C2) is connected via the second cervical vertebra with the functional circuit gallbladder (Th4 SMT®)/ liver (Th5 SMT®)/ eyes and tongue (C2).
The functional circuit lung (Th3 SMT®)/ colon (L1 SMT® u. L2 SMT®)/ nose and mouth(C4) is connected via the fourth cervical vertebra to the functional circuit stomach (Th6 SMT®)/ spleen/pancreas (Th8 SMT® u. Th7 SMT®).
Only the functional circuit bladder (L3 SMT®)/ kidneys (Th10 SMT® and Th11 SMT®)/ teeth and ears (C3)need no connection to other functional circuits, because due to its run over the whole spine it automatically has contact to all other functional circuits.
