7. The definition of the twelve meridians : • the main part of the meridian system • also known as “the twelve regular meridians” • including three yin and three yang meridians of the hand ,three yin and three yang meridians of the foot.

15. 1.2. 4 .3The tendons of the twelve meridians • 1. The definition : • (1)the areas where qi from the twelve meridians accumulates • (2)the regions where the twelve meridians are connected with the musculature and joints. 2. The distribution rule : • The same like the projection of the meridians that they are connected with on the body surface, especially on the four limbs. • 3.
