Course of the Channels and Point Qualifications
Bladder Channel (Foot-Taiyang)
Course: The Bladder Channel starts at the inner canthus of the eye. It ascends across the forehead and runs 2 cun lateral to the midline over the head to the neck. At the vertex, the Bladder Channel meets GV 20 and enters the brain. At BL 10, the Bladder Channel divides into an inter and an outer branch. The outer branch descends 3 cun lateral to the body midline down to the gluteal region. There, it intersects with the Gallbladder Channel at GB 30. From the gluteal region, this branch descends along the posterior aspect of the thigh to the popliteal fossa. Here, it rejoins with the inter branch at BL 40. The inter branch of the Bladder Channel descends through the nape of the neck, to the medial aspect of the rhomboid region, where it meets GV 13 and GV 14. Then, it continues to descend 1.5 cun lateral the midline to the sacrum. In the lumbar region, a branch enters the interior and intersects the Kidneys and joins its organ, the Bladder. From the sacrum, the branch descends along the posterior aspect of the thigh to the popliteal fossa. Here, it rejoins with the outer branch at BL 40. The Bladder Channel continues to descend through the posterior aspect of the leg, passing in the middle of the parts of the gastrocnemius muscle, downward to the lateral margin of the Achilles tendon and the lateral aspect of the foot. The Channel ends at the lateral end of the fifth toe, where it joins with the Kidney Channel.
