肺脉起于中焦出于大指之端注大肠经
手太阴肺之脉，起于中焦(在胃中脘)，下络大肠，环循胃口(胃口谓贲门)，上膈属肝，
系横出腋下，下循 内(臂肘也)，行少阴心主之前，下肘中(尺泽穴也)，循臂内上骨下廉(
直大指日上骨，内谓内侧)，入寸口(经渠穴也)，上鱼(循鱼际穴也，自大指本节后内侧)，
出大指之端(谓出少商穴也)。其支者，从腕后直出次指内廉出其端。
手太阴少血多气，《难经》云∶脉有是动，有所生病。是动者，气也；所生病者，血也
在气，气为是发；邪在血，血为所生病。是动则病，肺胀满，膨而喘咳，缺盆中痛，甚则交
两手而瞀，是为臂厥。主肺所生病者，咳嗽上气，喘渴烦心胸满， 臂内前廉痛，掌中热。
气盛有余，则肩背痛，风汗出中风，小便数而欠；气虚则肩背痛，寒，少气，不是叹息，溺
色变，卒遗矢无度。

手太阴肺经图
手太阴肺经的经脉，起始于中焦（位于胃的中脘部位），向下联络大肠，环绕胃的入口（胃口指贲门），向上穿过膈肌，归属于肝，横向穿出腋下，向下沿上臂内侧前行，走在手少阴心经和手厥阴心包经的前面，下行至肘窝中（即尺泽穴），沿前臂内侧桡骨下缘（“直大指日上骨”指桡骨，“内”指内侧），进入寸口（即经渠穴），上行至大鱼际（沿鱼际穴，自大指本节后的内侧），出于大拇指尖端（指出少商穴）。其支脉，从腕后直行至食指内侧边缘，出于其末端。
手太阴肺经血少气多，《难经》说：脉有“是动病”，有“所生病”。所谓“是动”，是指气分病变；所谓“所生病”，是指血分病变。邪在气分，气先发病；邪在血分，血后发病。“是动”则出现以下病症：肺胀满，腹部膨隆且喘咳，缺盆中疼痛，严重时双手交叉按于胸前而视物模糊昏蒙，这称为臂厥。主治肺经“所生”的病症：咳嗽气逆，气喘口渴，心烦胸满，上臂内侧前缘疼痛，手掌发热。若肺气盛有余，则肩背痛，易出汗且易受风邪侵袭，小便频数但量少；若肺气虚，则肩背痛，怕冷，气短，喜欢叹气，尿液颜色改变，突然大便失禁无节制。
手阳明大肠经图
手阳明大肠经的经脉，起始于食指内侧末端（即商阳穴），沿手指上缘，出于合谷穴两骨之间，上行进入两筋之中，沿前臂上缘（沿阳溪穴），进入肘部外侧（曲池穴），沿上臂外侧前缘，上行至肩部，出于肩峰前缘（肩峰指肩部的骨头，即肩端），上行出于柱骨（肩井等穴）的交会处，向下进入缺盆（缺盆穴位于锁骨上窝凹陷中），联络肺，向下穿过膈肌，归属于大肠。其支脉，从缺盆直行而上颈部（颈，即头茎），贯穿面颊，进入下齿中，环绕口唇，在人中穴处左右交叉（水沟穴），左侧走向右侧，右侧走向左侧，上行夹行于鼻孔两旁。
手阳明大肠经多血多气，“是动”则出现以下病症：牙齿疼痛，腮肿，主治津液代谢失常所生的病症：目黄，口干，鼻衄，喉痹，肩前痛，食指和拇指疼痛且活动不便。
Figure of the Hand-Taiyin Lung Meridian
The Lung meridian originates in the middle jiao (Middle Burner), emerges at the tip of the thumb, and transmits to the Large Intestine meridian.
The meridian of Hand-Taiyin Lung originates in the middle jiao (located at the Zhongwan point in the stomach region), descends to connect with the Large Intestine, circles around the cardia (the "stomach opening" refers to the cardia), ascends through the diaphragm, and attaches to the Liver. It branches out horizontally from below the axilla, descends along the medial aspect of the upper arm, running anterior to the Heart meridian of Hand-Shaoyin and the Pericardium meridian of Hand-Jueyin, descends into the cubital fossa (i.e., Chize [LU5]), follows the lower border of the radius on the medial aspect of the forearm (where "bone pointing to the thumb daily" refers to the radius, and "inner" refers to the medial side), enters the Cun Kou (i.e., Jingqu [LU8]), ascends to the Thenar eminence (following Yuji [LU10, from the medial side posterior to the first metacarpophalangeal joint), and emerges at the tip of the thumb (referring to Shaoshang [LU11]). Its branch arises from behind the wrist, goes straight to the medial border of the index finger, and emerges at its tip.
The Hand-Taiyin Lung meridian has less blood and more Qi. The *Nan Jing* states: "Meridians have 'Shi Dong' diseases and 'Suo Sheng Bing' diseases." "Shi Dong" refers to Qi-level pathology; "Suo Sheng Bing" refers to Blood-level pathology. When pathogenic factors are in the Qi, the Qi manifests disease first; when in the Blood, the Blood manifests disease later. "Shi Dong" results in: lung distension and fullness, abdominal bloating with wheezing and coughing, pain in the supraclavicular fossa (Quepen), and in severe cases, crossing both hands over the chest with visual blurring or faintness, known as Bi Jue (Arm Jue). It primarily treats "Suo Sheng Bing" of the Lung: cough with qi rebellion, asthma, thirst, vexation, chest fullness, pain along the anteromedial aspect of the arm, and heat in the palm. If Lung Qi is excessive, there is shoulder and back pain, sweating upon exposure to wind, frequent urination with scanty volume; if Lung Qi is deficient, there is shoulder and back pain, aversion to cold, shortness of breath, sighing, changes in urine color, and sudden involuntary defecation.
Figure of the Hand-Yangming Large Intestine Meridian
The Large Intestine meridian originates at the tip of the thumb, runs alongside the nostrils, and transmits to the Stomach meridian.
The meridian of Hand-Yangming Large Intestine originates at the radial side of the tip of the index finger (i.e., Shangyang [LI1]), follows the radial border of the finger, emerges between the two bones at Hegu (LI4), ascends into the space between the two tendons, follows the radial border of the forearm (along Yangxi [LI5]), enters the lateral aspect of the elbow (Quchi [LI11]), follows the lateral anterior aspect of the upper arm, ascends to the shoulder, emerges anterior to the acromion (the "acromion" refers to the bone at the end of the shoulder), ascends past the intersection of the Zhu Gu (shoulder wells such as Jianjing [GB21]), descends into the Quepen (supraclavicular fossa, where Quepen points are located in the depression above the clavicle), connects with the Lung, descends through the diaphragm, and attaches to the Large Intestine. Its branch arises from the Quepen, goes straight up the neck (the neck is the stem of the head), passes through the cheek, enters the lower teeth, circles the lips, crosses at Renzhong (Shuigou [GV26]), moving from left to right and right to left, ascending to flank both sides of the nostrils.
The Hand-Yangming Large Intestine meridian has abundant blood and abundant Qi. "Shi Dong" results in: toothache and swelling of the gums. It primarily treats diseases arising from disorders of Jin Ye (Body Fluids): yellow eyes, dry mouth, epistaxis, throat obstruction, pain in the anterior shoulder, and pain with dysfunction of the index and thumb fingers.
