There are 14 ‘main’ meridians or pathways joining the acupuncture points. 12 meridians are bilateral (both on the right and left). And 2 are midline on the body (front and back). There have been new meridians discovered which are called “Extra Meridians”. I am not covering them at this time.
Each meridian has a definite pathway on the body, and is divided into internal and external pathways.
The internal pathway begins at an organ. It traverses inside the body and is linked to the external pathway at the ‘starting’ acupuncture point.
