(This meridian originates at the Jingming (BL1) acupoint and terminates at the Zhiyin (BL67) acupoint.)

The Foot-Taiyang Bladder Channel of Hand-Yangming starts from the inner canthus, ascends to the forehead, and intersects at the vertex. Its branch extends from the vertex to the upper angle of the ear. The main trunk enters the brain from the vertex, emerges again, descends separately through the nape, follows the medial aspect of the shoulder blade, flanks the spine to reach the middle of the waist, enters internally to connect with the Kidney and belongs to the Bladder. Another branch descends from the middle of the waist, flanking the spine, penetrates the buttocks, and enters into the popliteal fossa. A further branch separates on the left and right from the medial aspect of the shoulder blade, descends separately penetrating the scapula, flanks the interior of the spine, passes through the hip pivot, follows the lateral posterior aspect of the thigh, and merges in the popliteal fossa from the posterior margin. It then descends through the calf muscle, emerges posterior to the lateral malleolus, follows the Jinggu (BL64) acupoint, and reaches the lateral side of the little toe. When this channel is disturbed, it causes disease characterized by headache striking upwards, eyes feeling as if they are falling out, the neck feeling as if being pulled, back pain and waist pain as if broken, inability to flex the thigh, stiffness in the popliteal region as if knotted, and pain in the calf as if torn; this is called "Huai Jue" (Ankle-Jue). This channel governs diseases related to the sinews, including hemorrhoids, malaria, mania and epilepsy, pain in the vertex, occiput, and neck, yellowing of the eyes with tearing, nasal congestion and epistaxis, pain throughout the neck, back, loins, sacrum, and feet, and dysfunction of the little toe. For these various diseases, excess conditions are treated with draining methods, deficiency conditions with tonifying methods, heat conditions with rapid needling, cold conditions with retained needling, sinking conditions with moxibustion, and neither-excess-nor-deficiency conditions are treated by selecting points from the channel itself. Excess conditions present with the Renying (ST9) pulse being more than twice as large as the Cunkou (Radial) pulse; deficiency conditions present with the Renying pulse being smaller than the Cunkou pulse.

The upper part of the head is called the Vertex (Dian), the back of the neck is called the Nape (Xiang), the lower posterior aspect of the shoulder is called the Shoulder Blade (Jianbo), the vertebral column is called the Spine (Ji), the transverse bone above the sacrum is called the Waist (Yao), the muscles flanking the spine are called the Diaphragm Muscles (Lv), the sides flanking the waist and hip bones are called the Pivot (Ji), the area posterior to the Pivot is called the Buttocks (Tun), the flexed area behind the knee is called the Popliteal Fossa (Nao), the lateral aspect of the thigh is called the Thigh (Bi), the area below the Jieguc bone is called the Hip Pivot (Bishu), and the gastrocnemius is called the Calf Muscle (Shuan).

The Foot-Taiyang Bladder Channel receives the intersection from the Hand-Taiyang Small Intestine Channel. It originates at the Jingming (BL1) acupoint in the inner canthus, ascends to the forehead, follows the Canzhu (BL1) acupoint, passes through the Shenting (GV24) acupoint, traverses the Qucha (BL8), Wuchu (BL8), Chengguang (BL9), and Tongtian (BL7) acupoints. From Tongtian, it runs obliquely to the left and right, intersecting at the Baihui (GV20) acupoint on the vertex. Its branch extends from the vertex to Baihui, reaching the upper angle of the ear. These one meridian and one collateral vessel ascend to the head. The main trunk enters the brain via the Tongtian (BL7), Luoque (BL9), and Yuzhen (GB9) acupoints, emerges again to descend to the nape to reach the Tianzhu (BL10) acupoint. From Tianzhu, it descends along the medial aspect of the shoulder blade, flanking the spine at a distance of 1.5 cun on each side, descending through the Dazhu (BL11), Fengmen (BL12), and other Shu points. Thereby, it reaches the middle of the waist, enters internally along the Lv muscles to connect with the Kidney, and descends to belong to the Bladder. Its divergent branch follows the waist and hips from the middle of the waist, descends flanking the spine, traverses the Shangliao (BL31), Ciliao (BL32), Zhongliao (BL33), Xialiao (BL34), and Huiyang (BL35) acupoints, descends through the buttocks to the Chengfu (BL36), Yinmen (BL37), Fupi (BL38), and Weiyang (BL39) acupoints, and enters the Weizhong (BL40) acupoint in the popliteal fossa. Another divergent branch consists of the acupoints in the second row flanking the spine, 3 cun apart on each side. Descending from Tianzhu (BL10), it separates on the left and right from the medial aspect of the shoulder blade, descends separately penetrating the scapula and Lv muscles, traversing the Fufen (BL17), Pohu (BL42), Gohuang (BL43), Shentang (BL44), Ge Guan (BL48), Hunmen (BL47), Yanggang (BL46), Yishe (BL45), Weicang (BL45), Huangmen (BL52), Zhishi (BL52), Baohuang (BL54), and Zhbian (BL54) acupoints. It descends through the sacral and gluteal regions, passes through the hip pivot, and follows the medial aspect of the hip pivot, between 1.5 cun external to Chengfu (BL36), descending to merge with the branch that previously entered the popliteal fossa. It descends along Heyang (BL56), penetrates the calf muscle, traverses the Chengjin (BL57), Chengshan (BL58), Feiyang (BL58), and Fuyang (BL59) acupoints, emerges posterior to the lateral malleolus at the Kunlun (BL60), Pucan (BL61), Shenmai (BL62), and Jinmen (BL63) acupoints, follows the Jinggu (BL64), Shugu (BL65), and Tonggu (BL66) acupoints, and reaches the Zhiyin (BL67) acupoint on the lateral side of the little toe, thereby connecting with the Foot-Shaoyin Kidney Channel.
