腕下兑骨为踝，脊两旁为膂，膂上两角为肩解，肩解下成片骨为肩胛，目外角为锐 ，目下为 ，目内角

手太阳受手少阴心经之交，脉起于小指少泽穴，穴由是循外侧之前谷、后溪，上腕出踝中，历腕骨、阳谷
、养老穴，直上循臂骨下廉，支正出肘内侧两筋之间，历小海穴，上循 外廉，行手阳明、少阳之外，上肩循
肩贞、 俞、天宗、秉风、曲垣、肩
外俞、肩中俞诸穴，乃上会大椎，左右相交于两肩之上，自交肩下入缺盆，循肩向腋下行，当膻中之分，络心

小肠穴，十九中。路从少泽，步前谷后溪之隆；道遵腕骨，观阳谷养老之崇。得支正于小海，逐肩贞以相
从。值 俞兮过天宗，乘秉风兮曲垣中。肩外俞兮肩中俞，启天窗兮见天容。匪由颧 ，曷造听宫。
小指端外为少泽，前谷外侧节前觅，节后捏拳取后溪，腕骨腕前骨陷侧，兑骨下陷阳谷讨，腕上一寸名养
老，支正腕后量五寸，小海肘端五分好，肩贞胛下两骨解， 俞大骨下陷保，天宗秉风后骨中，秉风 外举有
空，曲垣肩中曲胛陷，外俞胛后一寸从，肩中二寸大杼旁，天窗扶突后陷详，天容耳下曲颊后，颧 面 锐端

手腕下方的突起骨头称为踝，脊柱两侧竖立的肌肉称为膂，膂上方的两个角称为肩解，肩解下方成片状的骨头称为肩胛，眼睛的外眼角称为锐眦，眼睛下方称为目下，眼睛的内眼角称为内眦。
手太阳小肠经与手少阴心经相交接，脉气起于小指末端的少泽穴，从此处沿着外侧的前面经过前谷穴、后溪穴，向上到达手腕，穿出踝骨中间，依次经过腕骨穴、阳谷穴、养老穴，直上沿着臂骨的下缘，从支正穴出于肘内侧两条筋之间，经过小海穴，向上沿着肱骨外缘，走在手阳明大肠经和手少阳三焦经的外侧，向上经过肩部，循行经过肩贞穴、天宗穴（注：原文“ 俞”结合上下文及穴位歌诀应为天宗或肩外俞等，此处依原文留白处理，但根据《经络解》常规理解及下文歌诀“值 俞兮过天宗”，此处“ 俞”极可能指代肩外俞或特定语境下的穴位，鉴于原文缺字，翻译时保留位置描述）、天宗穴、秉风穴、曲垣穴、肩外俞穴、肩中俞穴等穴位，于是向上会合于大椎穴，左右在双肩上方相交，从交肩穴向下进入缺盆，沿着肩膀向腋下方向下行，当膻中穴的分野处，联络心脏，沿着胃的系带，向下穿过横膈，经过上脘穴抵住胃部，向下行走于任脉的外侧，当肚脐上方二寸的位置，归属于小肠。它的分支，从缺盆沿着颈部的天窗穴、天容穴上行至面颊，抵住颧骨，上行至眼睛外眼角，经过瞳子髎穴，然后进入耳中，沿着听宫穴而终结。另一分支，沿着面颊上行至鼻旁，到达眼睛内眼角睛明穴，以斜行的络脉联系颧部，从而与足太阳膀胱经相交接。
小肠经共有十九个穴位。路线从少泽穴开始，步伐经过前谷、后溪穴所在的高隆之处；道路遵循腕骨穴，观察阳谷、养老穴的高崇之处。在支正穴与小海穴相接，追随肩贞穴一同前行。遇到肩外俞穴时经过天宗穴，乘着秉风穴、曲垣穴之中。肩外俞穴和肩中俞穴，开启天窗穴、见到天容穴。如果不是通过颧骨部位，怎能到达听宫穴呢？
小指末端外侧是少泽穴，在前谷穴外侧、掌骨节前寻找；节后捏拳取后溪穴；腕骨穴在腕前骨头的凹陷侧面；兑骨（尺骨茎突）下方的凹陷处找阳谷穴；手腕上一寸处名为养老穴；支正穴在腕后量五寸处；小海穴在肘端五分好；肩贞穴在肩胛骨下两骨缝隙间；肩外俞穴在大骨下方的凹陷处保存；天宗穴在秉风穴后的骨头中间；秉风穴在外侧举起手臂有空隙；曲垣穴在肩中部曲胛骨的凹陷处；外俞穴在肩胛后一寸处跟随；肩中穴在二寸大杼穴旁边；天窗穴在扶突穴后的凹陷处详细查找；天容穴在耳下曲颊后方；颧骨部位在面部外眼角端测量；听宫穴在耳端大小如豆粒处，这就是小肠手太阳经的穴位。
The protruding bone below the wrist is called the ankle (huái). The muscles standing vertically on both sides of the spinal column are called the lumbar muscles (lǚ). The two angles above the lumbar muscles are called the shoulder junction (jiān jiě). The flat bones below the shoulder junction are called the scapula (jiān jiǎ). The outer corner of the eye is called the acute canthus (ruì zì). The area below the eye is called the lower eye (mù xià). The inner corner of the eye is called the inner canthus (nèi zì).
The Hand-Taiyang Small Intestine Channel intersects with the Hand-Shaoyin Heart Channel. The pulse originates at the Shaose (SI1) acupoint at the tip of the little finger. From there, it follows the anterior aspect of the lateral side, passing through the Qian Gu (SI2) and Hou Xi (SI3) acupoints, ascends to the wrist, exits from the middle of the ankle bone, and successively passes through the Wan Gu (SI4), Yang Gu (SI5), and Yang Lao (SI6) acupoints. It goes straight up along the lower border of the arm bone. The Zhi Zheng (SI7) branch emerges between the two tendons on the medial side of the elbow. It passes through the Xiao Hai (SI8) acupoint, ascends along the lateral border of the humerus, runs on the lateral side of the Hand-Yangming Large Intestine Channel and Hand-Shaoyang Sanjiao Channel, and ascends to the shoulder, traversing the Jian Zhen (SI9), Tian Zong (SI11), Bing Feng (SI12), Qu Yuan (SI13), Jian Wai Shu (SI14), and Jian Zhong Shu (SI15) acupoints. It then ascends to converge at the Da Zhui (GV14) acupoint, crossing over each other above the two shoulders. From the intersection point, it descends into the Que Pen (Clavicular fossa), follows the shoulder downwards towards the axilla, reaches the region corresponding to Dan Zhong (CV17), connects with the Heart, follows the gastric system, descends through the diaphragm, passes through the Shang Wan (CV13) acupoint, reaches the Stomach, descends lateral to the Ren Mai (Conception Vessel), and at the level of two cun above the umbilicus, belongs to the Small Intestine. Its branch from the Que Pen follows the neck, ascending through the Tian Chuang (SI16) and Tian Rong (SI17) acupoints to the cheek, reaching the zygomatic bone, ascending to the outer canthus of the eye, passing through the Tong Zi Liao (GB1), entering the ear, following the Ting Gong (SI19) acupoint to terminate. Another branch follows the cheek upwards to the nose, reaches the Jing Ming (BL1) acupoint at the inner canthus of the eye, and via an oblique collateral network, connects with the zygomatic region, thereby intersecting with the Foot-Taiyang Bladder Channel.
There are nineteen acupoints in the Small Intestine Channel. The route starts from Shaose (SI1), stepping upon the prominence of Qian Gu (SI2) and Hou Xi (SI3). The path follows Wan Gu (SI4), observing the elevation of Yang Gu (SI5) and Yang Lao (SI6). Meeting Zhi Zheng (SI7) at Xiao Hai (SI8), one follows Jian Zhen (SI9). Encountering Jian Wai Shu (SI14), one passes Tian Zong (SI11); riding through Bing Feng (SI12) and Qu Yuan (SI13). Jian Wai Shu (SI14) and Jian Zhong Shu (SI15) open Tian Chuang (SI16) and reveal Tian Rong (SI17). Without passing the zygomatic bone, how could one reach Ting Gong (SI19)?
Shaose (SI1) is located laterally at the tip of the little finger. Qian Gu (SI2) is sought on the lateral side of the metacarpal bone, anterior to the joint. Hou Xi (SI3) is taken by making a fist posterior to the joint. Wan Gu (SI4) is found in the depression on the lateral side of the styloid process of the ulna anterior to the wrist. Yang Gu (SI5) is sought in the depression below the styloid process of the ulna (Dui Gu). Yang Lao (SI6) is named one cun above the wrist. Zhi Zheng (SI7) is measured five cun posterior to the wrist. Xiao Hai (SI8) is good at five fen from the end of the elbow. Jian Zhen (SI9) is between the two bone gaps below the scapula. Jian Wai Shu (SI14) is preserved in the depression below the large bone. Tian Zong (SI11) is in the middle of the bone posterior to Bing Feng (SI12). Bing Feng (SI12) has an empty space when the arm is raised laterally. Qu Yuan (SI13) is in the depression of the curved scapula in the middle of the shoulder. Jian Wai Shu (SI14) follows one cun posterior to the scapula. Jian Zhong Shu (SI15) is beside Da Zhu (BL11) at two cun. Tian Chuang (SI16) is detailed in the depression posterior to Fu Tu (LI16). Tian Rong (SI17) is posterior to the curved jaw below the ear. The zygomatic region is measured at the sharp end of the face's lateral aspect. Ting Gong (SI19) is at the end of the ear, the size of a bean. These constitute the Hand-Taiyang Small Intestine Channel.
