手少阴心经的经脉，起始于心脏内部，归属于“心系”（连接心脏与其他脏器的组织），向下穿过膈肌，联络小肠。所谓“心系”有两部分：一部分向上与肺相连，进入肺的两叶之间；另一部分由肺系向下，曲折向后，沿着脊柱内部的细络相连，贯通脊髓并与肾脏相通，位置正当第七节椎骨之间。这是因为五脏的联系都通达于心，而心也通达五脏的联系。其分支从心系出发，挟着咽喉上行，联系到眼睛。其主干再次从心系出来，向上进入肺，再从腋下发出（此处为极泉穴的分界），向下沿着上臂内侧后缘行走，走在手太阴肺经和手厥阴心包经的后面，下行至肘部内侧边缘（此处为少海穴的分界），沿着前臂内侧后缘，到达手掌后方豌豆骨的末端，进入手掌内侧后缘，沿着小指的内侧，出于小指的尖端（手腕后的突起骨头称为兑骨）。
手太阳小肠经的经脉，起始于小指的末端，沿着手的尺侧（外侧）上行至腕部，出腕部的踝骨处（手臂骨骼尽头称为腕，手腕处的豌豆骨称为踝），直行向上沿着前臂尺侧下缘，出肘部内侧两筋之间，向上沿着上臂外侧下缘，出肩关节解溪处，环绕肩胛部，交会于肩上（脊柱两旁肌肉称为膂，膂上两角称为肩解，肩解下方成片状的骨头称为肩髀，髀通作胛），进入缺盆，联络心脏，沿着食管下行穿过膈肌，到达胃部，归属于小肠。其分支从缺盆出发，沿着颈部上行至面颊，到达目外角（目外角称为锐眦），然后进入耳中（目外角称为锐眦）。另一支别脉从面颊分出，上行至颧骨，到达鼻旁，直至目内角（眼下部位，目大角称为内眦，此处为睛明穴的分界，以交于足太阳膀胱经）。
足太阳膀胱经的经脉，起始于目内角（内眦），上行至额部，交会于头顶（发际前方称为额，脑上方称为巅顶）。其分支从头顶出发，上行至耳上角（此处在率谷穴分界，位于耳上如前三分，入发际一寸五分，凹陷宛宛之中）。其直行者从头顶进入，联络脑部，再出来，分别下行至项部（脑即头髓，颈上部称为脑，脑后称为项，此处当天柱穴分界，在大筋外侧，挟持颈部发际的凹陷中）。沿着肩膊内侧，挟持脊柱，到达腰部中间，深入循行于膂肉，联络肾脏，归属于膀胱（肩后下方称为肩膊，椎骨称为脊，尻上横骨称为腰，挟持脊柱的肉称为膂）。其分支从腰部中间下行，贯穿臀部，进入腘窝中（臀部和尻统称为臀，挟持腰髋骨两旁称为机，机后为臀，腓肠肌上方、膝后弯曲处称为腘，此处当委中穴）。另一支别脉从肩膊内侧左右分开，下行贯穿胂肉（膂肉称为胂，挟持脊柱的肉），经过髀枢（大腿外侧称为髀，犍骨之下称为髀枢），沿着大腿外侧后缘下行，在腘窝中与前面的分支汇合，向下贯穿小腿肚（腓肠肌），出于外踝之后，沿着京骨穴行至小趾外侧端（此处当至阴穴，交于足少阴肾经，腓肠肌也称为腨）。
The Hand-Shaoyin (Heart) Meridian originates within the heart, connects to the Xinxi (Heart System, tissues connecting the heart to other organs), descends through the diaphragm, and interrelates with the Small Intestine. The Xinxi has two parts: one part connects upward with the lungs and enters between the two lobes of the lungs; the other part descends from the lung system, curves backward, and is connected via fine collaterals along the spinal cord, communicating with the kidneys, located precisely at the level of the seventh vertebral segment. This is because the systems of the five zang organs all connect to the heart, and the heart connects to the systems of the five zang organs. Its branch arises from the Xinxi, runs alongside the pharynx, and connects to the eyes. The main trunk again emerges from the Xinxi, ascends into the lungs, and then exits from the axilla (boundary of the Jiquan [LI1] acupoint). It descends along the posterior medial aspect of the upper arm, running posterior to the Hand-Taiyin (Lung) and Hand-Jueyin (Pericardium) meridians, reaching the medial border of the elbow (boundary of the Shaohai [HT3] acupoint). It follows the posterior medial aspect of the forearm, reaches the end of the pisiform bone (Duigu, also known as the ulnar styloid process) at the back of the palm, enters the posterior medial aspect of the palm, follows the medial side of the little finger, and exits at its tip (the pisiform bone is called Duigu).
The Hand-Taiyang (Small Intestine) Meridian originates at the tip of the little finger, follows the ulnar side of the hand, ascends to the wrist, and emerges from the malleolus of the wrist (the end of the arm bones is called the wrist, and the pisiform bone at the wrist is called the malleolus). It goes straight up along the lower medial border of the forearm bone, emerges from the medial side of the elbow between two tendons, ascends along the lower lateral border of the upper arm, emerges from the shoulder joint gap (the muscles on both sides of the spine are called Lü, the two angles above Lü are called Jianjie, and the flat bone below Jianjie is called Jianbi, where Bi is a variant of Jia), enters the Supraclavicular Fossa (Quepen), interrelates with the heart, follows the pharynx, descends through the diaphragm, reaches the stomach, and belongs to the Small Intestine. Its branch arises from the Quepen, follows the neck, ascends to the cheek, reaches the outer canthus (the outer corner of the eye is called Ruizi), and then enters the ear (the outer corner is called Ruizi). Another branch separates from the cheek, ascends to the zygomatic arch, reaches the nose, and extends to the inner canthus (the area under the eye, the large angle of the eye is called Neijingming, boundary of the Jingming [BL1] acupoint, to intersect with the Foot-Taiyang Bladder Meridian).
The Foot-Taiyang (Bladder) Meridian originates at the inner canthus (Neijingming), ascends to the forehead, and intersects at the vertex (the area before the hairline is called E, and above the brain is called Dianding). Its branch arises from the vertex, ascends to the upper angle of the ear (this is at the boundary of the Shuaigu [GB8] acupoint, located three fen above the ear, entering the hairline by one cun and five fen, in a depression). The main trunk enters from the vertex, interrelates with the brain, then emerges, branches off, and descends to the nape (the brain is the marrow of the head, the upper neck is called Nao, and the back of the neck is called Xiang; this corresponds to the Tianzhu [BL10] acupoint, outside the large tendon of the neck, in the depression flanking the hairline of the neck). It follows the medial aspect of the scapula, flanks the spine, reaches the middle of the waist, descends deeply into the Lü muscle, interrelates with the kidneys, and belongs to the Bladder (the lower part behind the shoulder is called Jianbo, the vertebrae are called Ji, the transverse bone above the coccyx is called Yao, and the muscle flanking the spine is called Lü). Its branch descends from the middle of the waist, penetrates the buttocks, and enters the popliteal fossa (the buttocks and coccyx are collectively called Tun; the areas beside the hip bones are called Ji; behind Ji is the buttock; the area above the calf and behind the knee bend is called Guo, corresponding to the Weizhong [BL40] acupoint). Another branch separates from the medial aspect of the scapula, descends bilaterally, penetrates the Shen muscle (Lü muscle is called Shen, muscle flanking the spine), passes through the Bitu (lateral thigh is called Bi, below the fibular head is Bitu), follows the posterior lateral border of the thigh, converges with the previous branch in the popliteal fossa, descends through the calf (Gastrocnemius, also called Chuan), emerges posterior to the lateral malleolus, follows the Jinggu [BL64] acupoint, and reaches the lateral tip of the little toe (corresponding to the Zhiyin [BL67] acupoint, intersecting with the Foot-Shaoyin Kidney Meridian; the gastrocnemius is also called Shuan).
