甲乙经曰∶跷脉有阴阳，何者当其数？曰∶男子数其阳，女子数其阴，当数者为经，不当数者为络。
气之在身也，如水之流，如日月之行不休。故阴脉营其脏，而阳脉营其腑。如环之无端，莫知其纪，终而
复始。其流溢之气，内溉脏腑，外濡腠理。
阳跷脉，是足太阳膀胱经的别行分支。其脉气起始于足跟中部，从外踝下方的足太阳经申脉穴发出。（该穴位于外踝下方五分处的凹陷中，恰在爪甲与白肉交界的边缘）
经脉行至踝关节后方，环绕足跟，以仆参穴为本源。（该穴位于跟骨下方的凹陷中，拱起足部即可触及）向上行至外踝上方三寸处，以附阳穴为（关键穴位）。（该穴位于外踝上三寸，属于足太阳膀胱经的穴位）随后直上沿大腿外侧边缘，沿着胁肋后方上行至髀部。向上在（肩井穴附近）与手太阳小肠经、阳维脉相会合。（该交会点位于肩后大骨之下、肩胛骨上缘的凹陷中）继续上行经过肩部外侧边缘，在巨骨穴与手阳明大肠经相会合。（该穴位于肩尖端向上，两叉骨缝隙间的凹陷中）在肩髃穴处与手阳明大肠经、手少阳三焦经相会合。（该穴位于肩髃骨头处，肩端上方，两骨之间的凹陷宛宛之中。举起手臂取穴时有空隙感）再上行至人迎穴附近，夹口吻两侧，在地仓穴处与手阳明大肠经、足阳明胃经、任脉相会合。（地仓穴位于口角旁四分处，外侧近下位置有轻微脉搏跳动之处）接着同足阳明胃经一起向上行走于巨髎穴。（该穴位于鼻孔旁八分处，正对瞳孔，平齐水沟穴）再次在承泣穴处与任脉相会合。（该穴位于眼下七分处，正对瞳孔的凹陷中）到达目内眦（睛明穴），与手太阳小肠经、足太阳膀胱经、足阳明胃经、阴跷脉，共五条经脉在睛明穴相会合。（详见阴跷脉章节）从睛明穴上行进入发际，向下经过耳后，进入风池穴而终止。（风池穴位于耳后，夹玉枕骨下发际线的凹陷中）共计二十二个穴位。《难经》说：跷脉从足部运行至眼部，长度为七尺五寸，加上另一侧合计一丈五尺。
《甲乙经》说：跷脉分为阴跷和阳跷，哪一条计算其正经之数呢？回答说：男子计算阳跷，女子计算阴跷，应当计算的那条作为经，不应当计算的那条作为络。
人体之气，如同水流一般，如同日月运行一样永不停息。所以阴脉滋养五脏，阳脉滋养六腑。气血循环如圆环般没有开端，难以知晓其纪纲，周而复始，循环不息。其中流溢出来的气，向内灌溉脏腑，向外濡润腠理（皮肤纹理及汗孔）。
The Yang Qiao Mai (Yang Heel Vessel) is a divergent branch of the Foot-Taiyang Bladder Channel. Its pulse originates from the middle of the heel and emerges from below the lateral malleolus at the Shenmai (BL62) acupoint of the Foot-Taiyang channel. (Located 0.5 cun below the lateral malleolus in the depression, at the junction of the nail bed and white flesh.)
It passes behind the ankle, circles the heel, and takes Pucan (BL63) as its root. (Located in the depression under the calcaneus, accessible by arching the foot.) It ascends to three cun above the lateral malleolus, taking Fuyang (BL59) as [a key point]. (Located three cun above the lateral malleolus; it is an acupoint of the Foot-Taiyang channel.) It then goes straight up along the lateral aspect of the thigh, following the posterior hypochondrium to the hip. Ascending, it meets the Hand-Taiyang Small Intestine Channel and the Yang Wei Mai (Yang Linking Vessel) at [Jianjing area]. (Located in the depression below the large bone of the shoulder and the upper edge of the scapula.) It continues upward along the lateral edge of the shoulder, meeting the Hand-Yangming Large Intestine Channel at Jugu (SI14). (Located in the depression between the two forked bones, ascending from the tip of the shoulder.) It meets the Hand-Yangming Large Intestine Channel and the Hand-Shaoyang Sanjiao Channel at Jianyu (LI15). (Located at the Jianyu bone, above the shoulder end, in the deep depression between the two bones. The point can be located with a sense of emptiness when the arm is raised.) It ascends to the vicinity of Renying (ST9), flanking the corners of the mouth, and meets the Hand-Yangming, Foot-Yangming Stomach Channel, and Ren Mai (Conception Vessel) at Dicang (ST4). (Located 0.4 cun lateral to the corner of the mouth, where a slight pulsation can be felt slightly lower and outward.) Together with the Foot-Yangming Stomach Channel, it ascends to Juliao (ST3). (Located 0.8 cun lateral to the nostril, directly opposite the pupil, level with Shuigou.) It again meets the Ren Mai at Chengqi (ST1). (Located 0.7 cun below the eye, in the depression directly opposite the pupil.) Arriving at the medial canthus of the eye, it meets five channels—the Hand-Taiyang, Foot-Taiyang, Foot-Yangming, Yin Qiao Mai (Yin Heel Vessel)—at Jingming (BL1). (See Yin Qiao Mai for details.) From Jingming, it ascends into the hairline, descends behind the ear, enters Fengchi (GB20), and terminates. (Fengchi is located in the depression below the hairline, flanking the Yuzhen bone behind the ear.) There are twenty-two acupoints in total. The Nan Jing states: "The Qiao vessels run from the foot to the eye, measuring seven chi and five cun, totaling one zhang and five chi."
The Jia Yi Jing states: "Qiao vessels have Yin and Yang aspects. Which one counts as the principal vessel? The answer is: For men, count the Yang; for women, count the Yin. The one counted is the Jing (Principal Vessel); the one not counted is the Luo (Connecting Vessel)."
Qi in the body flows like water and moves ceaselessly like the sun and moon. Thus, Yin vessels nourish the Zang organs, while Yang vessels nourish the Fu organs. Like a circle without beginning or end, its order is hard to discern, yet it ends and begins anew. The overflowing Qi irrigates the internal Zang and Fu organs and moistens the external Couli (skin texture and pores).
