Concept of meridians
Meridian is a general term for meridians and collaterals. It serves as the pathway for the transportation of qi and blood throughout the body, thus connecting the viscera with extremities, the interior with the exterior as well as the upper with the lower. Meridians are the main trunks running longitudinally within the body, most of which run deeply inside and follow certain routes. Collaterals are the branches of meridians running reticular over the body. They run deeply or superficially within the body, most of which run in the shallow region and some often give a visible appearance on the surface of the body. The interconnection of meridians with collaterals throughout the body integrates the viscera, limbs and orifices, muscles and tendons into an organic whole, thus ensuring the normal performance of body activities.
