While we were looking for possible anatomical correlations for the gallbladder meridian, the first thing
we thought was that the highest part of its pathway is very similar to a sickle (falx-falcis in Latin), like the one that divides the right cerebral lobe from the left, called falx cerebri or cerebral falx. Although this was a good finding, it was not enough for
us. After giving a valid explanation for the presence of
the strange circle in the kidney acupuncture meridian,
we expect each meridian to have an univocal connection with the shape of the pertaining organ, or its embryologic development. And so it is. Although in Traditional Chinese Medicine (TCM) the brain is a curious - extraordinary organ, it is under the control of the liver and gallbladder. Thus
we started to compare the gallbladder meridian pathway with the gallbladder anatomy and the annexed biliary tree within the liver. So
we discovered that the first three segments of the gallbladder meridian (GB1 to GB2, GB2 to GB4 and GB4 to GB7) trace out the shape of the pancreatic duct and biliary common duct with hepatic ducts in an almost realistic way. The fourth segment (GB7 to GB12) continues to trace out the shape of the cystic duct and gallbladder body, as well as the lateral tract of the anterior-inferior margin of the liver's right lobe. In the picture below
we have overlapped the head-pathway of the gallbladder meridian onto three different liver-gallbladder images for a better understanding. The work goes on...
