属足少阳胆经（《灵枢》曰∶足少阳之脉，抵绝骨之端，下出外踝之前。所生病者，外
踝前及诸节皆痛。又曰∶足少阳之筋，上结外踝上。又曰∶足少阳之下，血气盛，则胫毛美长，外踝肥；血气
皆少，则胫无毛，外踝瘦无肉。《素问》曰∶膝痛淫泺胫酸，不能久立，治少阳之络，在外踝上五寸。注∶淫
泺，谓似酸痛而无力也。外踝上五寸，乃足少阳之络，光明穴也。沈承之曰∶手足六经，散而为十二则，曰∶
自下臂，外廉之中，手少阳也；外之上廉，手阳明也；外之下廉，手太阳也。自髀下胫，外廉之中，足少阳
也；外之前廉，足阳明也；外之后廉，足太阳也。自 下臂，内廉之中，手厥阴也；内之上廉，手太阴也；内
之下廉，手少阴也。自股下胫，内廉之中，足厥阴也；内之前廉，足太阴也；内之后廉，足太阴也。统而为
六则，曰∶外则三阳主之，中曰少阳，前曰阳明，后曰太阳；内则三阴主之，中曰厥阴，前日太阴，后曰少阴。
约而为三则，曰∶阳明与太阴为表里，故并居于前；太阳与少阴为表里，故并居于后；少阳与厥阴为表里，
故并居于中。在手为手经，在足为足经。虽若不齐，而实则一贯，学人知此，则易晓而不忘矣）。又属阳跷脉
（《难经》曰∶阳跷脉，起于跟中，循外踝上行入风池）。
归属于足少阳胆经（《灵枢》记载：足少阳经脉，抵达绝骨末端，向下出于外踝之前。其所发生的病症，包括外踝前部及各个关节疼痛。又记载：足少阳经筋，向上结聚于外踝上方。又记载：足少阳经之下，若血气旺盛，则小腿毛发美观修长，外踝丰满；若血气皆虚弱，则小腿无毛，外踝消瘦且无肉。《素问》记载：膝部疼痛、腿部酸软无力、不能久立，治疗足少阳经络，取穴在外踝上五寸。注释：淫泺，指感觉像酸痛但身体无力。外踝上五寸处，是足少阳经络穴光明穴。沈承之说：手足六经，分散为十二条经脉，其规律如下：从手臂下方至外侧中间，是手少阳经；外侧上部边缘，是手阳明经；外侧下部边缘，是手太阳经。从大腿下方至小腿，外侧中间，是足少阳经；外侧前部边缘，是足阳明经；外侧后部边缘，是足太阳经。从手臂下方至内侧中间，是手厥阴经；内侧上部边缘，是手太阴经；内侧下部边缘，是手少阴经。从大腿下方至小腿，内侧中间，是足厥阴经；内侧前部边缘，是足太阴经；内侧后部边缘，也是足太阴经（注：原文此处可能有误，通常后廉为足少阴，但依原文翻译）。统合为六条主要路径，其规律是：外侧由三阳经主导，中间是少阳经，前部是阳明经，后部是太阳经；内侧由三阴经主导，中间是厥阴经，前部是太阴经，后部是少阴经。概括为三条主要路径，其规律是：阳明经与太阴经互为表里，所以共同位于前部；太阳经与少阴经互为表里，所以共同位于后部；少阳经与厥阴经互为表里，所以共同位于中部。在上肢称为手经，在下肢称为足经。虽然看似不整齐，但实际上是一脉相通的，学习者了解这一点，就容易理解且不会忘记）。另外归属于阳跷脉（《难经》记载：阳跷脉，起于脚跟中部，沿外踝向上进入风池穴）。
Belongs to the Foot-Shaoyang Gallbladder Meridian (The *Ling Shu* states: The Foot-Shaoyang meridian reaches the end of the Jiegu bone, descends and emerges anterior to the lateral malleolus. Diseases occurring in this meridian include pain in the area anterior to the lateral malleolus and in various joints. It also states: The Foot-Shaoyang sinew channel ascends and binds above the lateral malleolus. Furthermore: Below the Foot-Shaoyang, if blood and qi are abundant, the leg hair is beautiful and long, and the lateral malleolus is fleshy; if both blood and qi are deficient, there is no leg hair, and the lateral malleolus is thin without flesh. The *Su Wen* states: Pain in the knees, heaviness and soreness in the calves with inability to stand for long periods, should be treated by the collateral of the Shaoyang of the Foot, located five cun above the lateral malleolus. Note: Yinluo refers to a sensation resembling soreness and weakness. Five cun above the lateral malleolus is the Luo-connecting point Guangming of the Foot-Shaoyang meridian. Shen Chengzhi said: The six meridians of the hand and foot, when dispersed into twelve, follow these rules: From the lower arm to the middle of the lateral aspect, it is the Hand-Shaoyang; at the upper edge of the lateral aspect, it is the Hand-Yangming; at the lower edge of the lateral aspect, it is the Hand-Taiyang. From the thigh down to the leg, at the middle of the lateral aspect, it is the Foot-Shaoyang; at the anterior edge of the lateral aspect, it is the Foot-Yangming; at the posterior edge of the lateral aspect, it is the Foot-Taiyang. From the lower arm to the middle of the medial aspect, it is the Hand-Jueyin; at the upper edge of the medial aspect, it is the Hand-Taiyin; at the lower edge of the medial aspect, it is the Hand-Shaoyin. From the thigh down to the leg, at the middle of the medial aspect, it is the Foot-Jueyin; at the anterior edge of the medial aspect, it is the Foot-Taiyin; at the posterior edge of the medial aspect, it is also the Foot-Taiyin [Note: Textual error likely intended Foot-Shaoyin]. Unified into six main pathways, the rule is: The lateral side is governed by the three Yang meridians, with Shaoyang in the middle, Yangming anteriorly, and Taiyang posteriorly; the medial side is governed by the three Yin meridians, with Jueyin in the middle, Taiyin anteriorly, and Shaoyin posteriorly. Summarized into three main pathways, the rule is: Yangming and Taiyin are exterior-interior pairs, thus residing together anteriorly; Taiyang and Shaoyin are exterior-interior pairs, thus residing together posteriorly; Shaoyang and Jueyin are exterior-interior pairs, thus residing together medially. In the upper limbs they are called Hand meridians, and in the lower limbs Foot meridians. Although they may appear irregular, they are essentially consistent. Understanding this makes it easy to comprehend and remember.) It also belongs to the Yang Qiao Mai (The *Nan Jing* states: The Yang Qiao Mai originates from the center of the heel, follows the lateral malleolus upward, and enters Fengchi).
