[Diagram of the Hand-Shaoyang Sanjiao Meridian]
The Sanjiao meridian originates at the tip of the fourth finger, reaches the outer canthus, and connects with the Gallbladder meridian.

The Hand-Shaoyang Sanjiao (Triple Burner) meridian originates at the tip of the ring finger (Guanchong, SI 1), ascends between the fingers (Yemen, SJ 2), follows the dorsal aspect of the hand to the wrist, emerges between the two bones of the forearm (Zhigou, SJ 6), ascends through the elbow, follows the lateral aspect of the upper arm to the shoulder, crosses posterior to the Foot-Shaoyang Gallbladder meridian, enters the supraclavicular fossa (Quepen, GB 12), and spreads in the chest center (Shanzhong, CV 17; located 1.5 cun below Yutang, CV 19, in the depression between the nipples). It disperses and connects with the Pericardium, descends through the diaphragm, and belongs to the Sanjiao. A branch arises from the Shanzhong, ascends out of the Quepen, travels up the neck behind the ear, emerges directly above the upper angle of the ear, then curves down to the cheek (or skull) to reach the infraorbital region. Another branch enters the ear from behind the ear, emerges anterior to the ear, passes through the Guest Master point (Keguren, ST 7; located in the depression anterior to the tragus when the mouth is open), crosses anteriorly at the cheek, and reaches the outer canthus.

The Hand-Shaoyang Sanjiao meridian has abundant Qi and scarce Blood. When the meridian is disturbed, symptoms include deafness, tinnitus, a muffled sensation in the head, swelling of the throat, and throat obstruction. If diseases arise from the Qi regulated by this meridian, symptoms include sweating, pain in the outer canthus, cheek pain, pain along the posterior ear, shoulder, arm, elbow, and lateral aspect of the forearm, and dysfunction of the ring and little fingers.

[Diagram of the Foot-Shaoyang Gallbladder Meridian]
The Gallbladder meridian originates at the outer canthus, enters the big toe, follows the interosseous space, emerges at the tip, and connects with the Liver meridian.

The Foot-Shaoyang Gallbladder meridian originates at the outer canthus, ascends to the frontal angle of the head, descends behind the ear, runs along the neck anterior to the Hand-Shaoyang Sanjiao meridian, reaches the shoulder, crosses posterior to the Hand-Shaoyang Sanjiao meridian, and enters the supraclavicular fossa. A branch enters the ear from behind the ear, emerges anterior to the ear, and reaches the posterior aspect of the outer canthus. Another branch diverges from the outer canthus, descends to the Daying point (ST 5), merges with the Hand-Shaoyang Sanjiao meridian, reaches the infraorbital region, descends to the Jiache point (ST 6), goes down the neck to merge with the supraclavicular fossa, descends into the chest, pierces the diaphragm, connects with the Liver, and belongs to the Gallbladder. It follows the interior of the hypochondrium, emerges at the Qichong point (ST 30), surrounds the pubic region, and enters transversely into the hip joint. The main trunk descends from the supraclavicular fossa into the axilla, passes along the lateral chest and costal margin, merges with the hip joint, descends along the lateral thigh, emerges at the lateral knee (Yanglingquan, GB 34), goes down anterior to the fibula (located in the depression), reaches the end of the Juegu (Yangfu, GB 38), emerges anterior to the lateral malleolus, follows the dorsum of the foot, and enters between the fourth and fifth toes. A branch diverges from the dorsum of the foot, enters between the big toe and the second toe, follows the medial aspect of the first metatarsal bone, emerges at the tip of the toe, returns to penetrate the nail bed, and emerges among the hair follicles (Sanmao).

The Foot-Shaoyang Gallbladder meridian has abundant Qi and scarce Blood. When the meridian is disturbed, symptoms include bitter taste in the mouth, frequent sighing, pain in the heart and hypochondrium preventing turning over, and in severe cases, a dusty complexion and lack of luster in the body. Heat on the lateral aspect of the foot indicates Yang Jue (Yang Reversal). This meridian governs the bones. Diseases governed by this meridian include headache, mandibular pain, pain in the outer canthus, swelling in the supraclavicular fossa, axillary swelling, "Horse Knife" and "Xia Ying" (types of scrofula or tumors), sweating with chills, malaria, and pain in the chest, hypochondrium, ribs, thigh, lateral knee, lower leg, Juegu, lateral malleolus, and various joints. There is also dysfunction of the fourth and fifth toes.
