（肘部是臂的节段，位于肩之下、腕之上）归属于手厥阴心包经（《灵枢》记载：手厥阴心主之脉，沿中指内侧上行，至肘内侧，进入小筋之下。又说：手厥阴心主之筋，与手太阴肺经之筋，共同结聚于肘内侧）。
〔肘内侧上部〕归属于手太阴肺经，〔肘内侧下部〕归属于手少阴心经（《灵枢》记载：手太阴肺经之脉，出于寸口，运行至肘内侧，进入大筋之下。又说：手少阴心经之筋，向上结聚于肘内侧，向下形成肘网。又说：肺和心有邪气，其病气会留滞于两肘）。
〔肘外侧中间〕归属于手少阳三焦经（《灵枢》记载：手少阳三焦经之脉，从臂外两骨之间出，向上贯穿肘部。又说：手少阳三焦经之筋，沿臂上行，结聚于肘部。又说：手阳明大肠经和手少阳三焦经的大络，起于五指之间，向上汇合于肘中）。
〔肘外侧上部〕归属于手阳明大肠经。〔肘外侧下部〕归属于手太阳小肠经（《灵枢》记载：手阳明大肠经之脉，沿臂上侧上行，进入肘外侧。又说：手太阳小肠经之筋，沿臂内侧上行，结聚于肘内锐骨之后，弹拨时，感应可传至小指上方。又说：仅肘部发热者，为腰以上热；仅手部发热者，为腰以下热；仅肘前发热者，为胸膺前热；仅肘后发热者，为肩背热；仅臂中部发热者，为腰背热；肘后下方三四寸处发热者，为肠中有虫。又说：手阳明大肠经之筋，沿臂上行，结聚于肘外侧）。

〔肘内侧中间〕归属于手厥阴心包经，〔肘内侧上部〕归属于手太阴肺经，〔肘内侧下部〕归属于手少阴心经（《灵枢》记载：手厥阴心包经之脉，下行于臂，行于两筋之间。又说：邪气中于阴分者，常从臂部开始。臂与腿，其阴面皮肤薄，肌肉柔润，因此都容易受风邪侵袭，唯独损伤其阴分）。兼属肝肾二经（张鸡峰说：臂细无力不能承受重物，这是肝肾气虚，风邪客居于营卫之间，使气血不能周流滋养四肢，所以出现此症，应当专门补益肝肾）。
(The elbow is the joint of the arm, located below the shoulder and above the wrist) It belongs to the Pericardium Meridian of Hand-Jueyin (The *Ling Shu* states: The vessel of the Heart Master (Pericardium) follows the medial aspect of the middle finger, ascends to the medial aspect of the elbow, and enters below the small tendon. It also states: The tendon of the Heart Master (Pericardium), along with the tendon of the Lung Meridian of Hand-Taiyin, both knot at the medial aspect of the elbow).
[The upper medial aspect] belongs to the Lung Meridian of Hand-Taiyin, [the lower medial aspect] belongs to the Heart Meridian of Hand-Shaoyin (The *Ling Shu* states: The vessel of the Lung Meridian of Hand-Taiyin emerges from the Cun Kou pulse point and travels to the medial aspect of the elbow, entering below the large tendon. It also states: The tendon of the Heart Meridian of Hand-Shaoyin ascends to knot at the medial aspect of the elbow, forming the 'elbow net' downwards. It also states: When there is evil qi in the Lung and Heart, its qi remains stagnant in both elbows).
[The middle lateral aspect] belongs to the Sanjiao Meridian of Hand-Shaoyang (The *Ling Shu* states: The vessel of the Sanjiao Meridian of Hand-Shaoyang emerges between the two bones of the forearm, ascending through the elbow. It also states: The tendon of the Sanjiao Meridian of Hand-Shaoyang follows the forearm and knots at the elbow. It also states: The great collaterals of the Large Intestine Meridian of Hand-Yangming and the Sanjiao Meridian of Hand-Shaoyang originate between the five fingers and ascend to converge in the center of the elbow).
[The upper lateral aspect] belongs to the Large Intestine Meridian of Hand-Yangming. [The lower lateral aspect] belongs to the Small Intestine Meridian of Hand-Taiyang (The *Ling Shu* states: The vessel of the Large Intestine Meridian of Hand-Yangming follows the upper lateral aspect of the forearm and enters the lateral aspect of the elbow. It also states: The tendon of the Small Intestine Meridian of Hand-Taiyang follows the medial aspect of the forearm and knots behind the sharp bone of the inner elbow; upon palpation, the sensation responds above the little finger. It also states: Heat exclusively in the elbow indicates heat above the waist; heat exclusively in the hand indicates heat below the waist; heat exclusively in the front of the elbow indicates heat in the anterior chest; heat exclusively in the back of the elbow indicates heat in the shoulder and back; heat exclusively in the middle of the arm indicates heat in the lumbar and back regions; heat three or four cun below the posterior elbow indicates intestinal parasites. It also states: The tendon of the Large Intestine Meridian of Hand-Yangming follows the forearm and ascends to knot at the lateral aspect of the elbow).
(Below the elbow, above the wrist) [The middle lateral aspect] belongs to the Sanjiao Meridian of Hand-Shaoyang, [the upper lateral aspect] belongs to the Large Intestine Meridian of Hand-Yangming, [the lower lateral aspect] belongs to the Small Intestine Meridian of Hand-Taiyang (The *Ling Shu* states: When disease begins in the arm, one should first select points on the Large Intestine Meridian of Hand-Yangming to induce sweating. Zhu Danxi said: Symptoms arising from the combination of Yin and Yang of the hands and feet are called pain in the lateral arm, which involves the Small Intestine Meridian of Hand-Taiyang and the Sanjiao Meridian of Hand-Shaoyang).
[The middle medial aspect] belongs to the Pericardium Meridian of Hand-Jueyin, [the upper medial aspect] belongs to the Lung Meridian of Hand-Taiyin, [the lower medial aspect] belongs to the Heart Meridian of Hand-Shaoyin (The *Ling Shu* states: The vessel of the Pericardium Meridian of Hand-Jueyin descends the arm, running between the two tendons. It also states: Evil invading the Yin aspect often starts from the arm. The arm and leg, their Yin surfaces have thin skin and moist/fleshy tissue, thus they are all susceptible to Wind evil, but specifically injure their Yin aspects). It also jointly belongs to the Liver and Kidney meridians (Zhang Jifeng said: Thin arms lacking strength and unable to bear weight indicate deficiency of Qi in the Liver and Kidneys, with Wind evil lodging in the Ying and Wei levels, preventing Qi and Blood from circulating and nourishing the four limbs, hence this symptom arises; treatment should focus on tonifying the Liver and Kidneys).
