Jing-Luo System
Traveling course of the regular meridian
It starts from LI 1 Shangyang (商阳), on the radial side of the tip of the index finger, runs upward along the anterior portion of the lateral aspect of the upper limb to the shoulder, goes up to the seventh cervical vertebra [DU 14 Dazhui (大椎)], where it meets the Du Meridian, descends into the supraclavicular fossa to communicate with the lung, and homes to the large intestine.
One branch from the supraclavicular fossa runs upward to the neck and cheek, enters the lower teeth and gums, curves around the mouth to the upper lip, crosses the opposite meridian at the philtrum [DU 26 Renzhong ], and ends on the side of the nose at LI 20 Yingxiang (迎香), where it links with the Stomach Meridian.
Traveling course of the divergent meridian
It diverges from the regular Large Intestine Meridian on the hand, and ascends the arm to the shoulder and breast. From the top of the shoulder at LI 15 Jianyu it enters the spine at the nape and runs downward to connect with the large intestine and lung. One branch travels along the throat and emerges at the supraclavicular fossa, where it rejoins the regular Large Intestine Meridian.
Traveling course of the collateral
It separates from the regular Large Intestine Meridian at LI 6 Pianli (偏历) and joins the Lung Meridian of Hand Taiyin 3 cun above the wrist. One branch ascends the arm to the shoulder through LI 15 Jianyu (肩髃), , and reaches the jaw and teeth. From the cheek, another branch enters the ear to join the zong mai or the gathering place of the Meridians of the Large Intestine, Stomach, Small Intestine, Gall Bladder, and San Jiao.
The muscle region
It starts at the tip of the index finger at LI 1 Shangyang (商阳) and knots at the dorsum of the wrist. Then it ascends the forearm and binds at the lateral aspect of the elbow. It continues to ascend the upper arm and binds at the shoulder. One branch winds around the scapula and attaches to the spine. From the shoulder the straight branch runs upward to the neck, where a branch ascends across the cheeks to bind at the side of the nose. Meanwhile, the straight branch continues to ascend anterior to the small intestine muscle region, crosses the temple to the corner of the forehead, and crosses over the top of the head to connect with the mandible on the opposite side.
The cutaneous regions
