\r小肠腑形\ps127a71.bmp\r
经曰∶小肠者，受盛之官，化物出焉。食下则肠实而胃虚。又云∶小肠为赤肠。
胃之下口，小肠之上口也，在脐上二寸，水谷于是分焉。大肠上口，小肠之下口也，至是而
泌别清浊，水液渗入膀胱，滓秽流入大肠。
手太阳之脉起于小指之端，循手外侧上腕，出踝中，直上循臂骨下廉，出肘内侧两骨之间，
上循 外后廉，出肩解，绕肩胛，交肩上，入缺盆，络心，循咽，下膈抵胃，属小肠。
其支者，从缺盆循颈上颊至目锐 ，却入耳中。其支别者，别循颊上 ，抵鼻至目肉 。凡一十
九穴，左右共三十八穴。

手少阴心经共有九个穴位，分别是极泉、青灵、少海（位置较深）。灵道、通里、阴郄（原文作“阴 邃”，据《针灸甲乙经》及上下文修正为阴郄）、神门、少府、少冲。
手少阴心经起始于极泉穴，位于腋下筋脉之间，经脉由此进入胸部。青灵穴在肘后节（尺骨鹰嘴）上三寸处。少海穴在肘内侧关节后方。灵道穴在掌后横纹上一寸半处。通里穴在腕后横纹上一寸处。阴郄穴在腕后五分处，可触及动脉搏动。神门穴在掌后锐骨（豌豆骨）隆起处。少府穴在掌后节与劳宫穴垂直相对的位置。少冲穴在小指内侧取穴。
小肠腑的形态与功能：
经典记载说：小肠是负责接受和盛纳食物的器官，负责将食物转化为精微物质。食物下行则肠道充实而胃中空虚。又说：小肠被称为赤肠。胃的下口是小肠的上口，位于脐上二寸处，水谷在此处开始分离。大肠的上口是小肠的下口，到达此处时，小肠分别清浊，水液渗入膀胱，糟粕流入大肠。
手太阳小肠经的脉气起于小指末端，沿着手外侧上行至手腕，出于踝中（指尺骨茎突处），直上沿前臂骨下缘，出于肘内侧两骨（尺骨鹰嘴与肱骨内上髁）之间，向上沿上臂外后侧下缘，出于肩解（肩关节后方），绕行肩胛部，交会于肩上，进入缺盆（锁骨上窝），联络心脏，沿咽部，向下穿过膈肌抵达胃部，归属于小肠。
其分支，从缺盆沿颈部上行至面颊，到达目外眦，再退回进入耳中。另一分支，别行沿面颊上行至鼻旁，抵达目内眦。本经共有十九个穴位，左右两侧共三十八个穴位。
少泽穴（又名少吉）：位于手小指末端外侧，距爪甲角下一分陷中。为手太阳小肠经所出之井穴，五行属金。针刺一分，艾灸一壮。
【主治】疟疾寒热往来，无汗，喉痹舌强，心烦咳嗽，抽搐臂痛，颈项疼痛不能回顾，目生翳膜。
前谷穴：位于手小指外侧本节（掌指关节）前陷中。为手太阳小肠经所溜之荥穴，五行属水。针刺一分，艾灸三壮。
【主治】热病无汗，疟疾癫疾，耳鸣喉痹，颈项颊肿牵引耳后，咳嗽鼻塞吐血衄血，手臂疼痛不能举起，妇女产后无乳汁。
The Hand-Shaoyin Heart Meridian contains nine acupoints: Jiquan (HT1), Qingling (HT2), Shaohai (HT3, located deeply), Lingdao (HT4), Tongli (HT5), Yinxi (HT6), Shenmen (HT7), Shaofu (HT8), and Shaochong (HT9).
The Hand-Shaoyin Heart Meridian originates at Jiquan (HT1), located between the tendons in the axilla, where the meridian enters the chest. Qingling (HT2) is three cun above the elbow joint (olecranon). Shaohai (HT3) is located posterior to the medial aspect of the elbow joint. Lingdao (HT4) is one and a half cun proximal to the transverse crease of the wrist. Tongli (HT5) is one cun proximal to the transverse crease of the wrist. Yinxi (HT6) is taken five fen proximal to the wrist crease, where the arterial pulse can be palpated. Shenmen (HT7) is located at the prominence of the sharp bone (pisiform) distal to the palm. Shaofu (HT8) is directly opposite Laogong (PC8) relative to the post-palm joint. Shaochong (HT9) is located on the medial side of the little finger.
Morphology and Function of the Small Intestine Zang-Fu:
The Classics state: The Small Intestine is the official responsible for receiving and containing, transforming substances. When food descends, the intestine becomes full while the stomach becomes empty. It is also said that the Small Intestine is the "Red Intestine." The lower opening of the Stomach is the upper opening of the Small Intestine, located two cun above the umbilicus, where water and grain begin to separate. The upper opening of the Large Intestine is the lower opening of the Small Intestine; here, clear and turbid substances are separated: fluid seeps into the Bladder, while dregs flow into the Large Intestine.
The vessel of the Hand-Taiyang Small Intestine Meridian originates at the tip of the little finger, follows the lateral aspect of the hand up to the wrist, emerges from the ankle region (styloid process), goes straight up along the lower border of the forearm bone, emerges between the two bones at the medial aspect of the elbow, ascends along the posterior-lower border of the upper arm, emerges from the shoulder joint (jianjie), winds around the scapula, intersects at the shoulders, enters the supraclavicular fossa (quepen), connects with the Heart, follows the pharynx, passes through the diaphragm to reach the Stomach, and belongs to the Small Intestine.
Its branch arises from the supraclavicular fossa, follows the neck up to the cheek, reaches the outer canthus of the eye, and then re-enters the ear. Another branch diverges, follows the cheek upwards to the nose, and reaches the inner canthus of the eye. There are nineteen acupoints in total, thirty-eight on both sides combined.
Shaoze (SI1, also known as Shaoji): Located at the ulnar end of the little finger, one fen distal to the corner of the nail in the depression. It is the Jing-Well (Metal) point of the Hand-Taiyang Small Intestine Meridian. Needle 1 fen, moxibustion 1 cone.
【Indications】 Malaria with chills and fever, absence of sweating, throat obstruction with tongue stiffness, vexation, cough, convulsions with arm pain, neck and nape pain with inability to turn the head, cornea opacity.
QianGu (SI2): Located in the depression anterior to the metacarpophalangeal joint on the ulnar side of the little finger. It is the Ying-Spring (Water) point of the Hand-Taiyang Small Intestine Meridian. Needle 1 fen, moxibustion 3 cones.
【Indications】 Febrile diseases with absence of sweating, malaria and epilepsy, tinnitus and throat obstruction, swelling of the neck, nape, and cheek radiating to behind the ear, cough, nasal congestion, hematemesis and epistaxis, arm pain with inability to lift, postpartum agalactia in women.
Houxi (SI3): Located in the depression posterior to the metacarpophalangeal joint on the ulnar side of the little finger; take the point with the fist clenched. It is the Shu-Stream (Wood) point of the Hand-Taiyang Small Intestine Meridian. Needle 1 fen, moxibustion 1 cone.
