\r督脉之图\p06-d32a27.bmp\r
本篇此处无督脉任脉之说，止下文有督脉任脉之别盖指络穴言也。今附二图于此，则十四经始全。
督脉行于背部正中，共有十七个穴位，起始于长强穴。接着是腰俞、阳关，进入命门、悬枢之间，沿着脊中筋束向上到达至阳穴。灵台、神道、身柱，陶道与大椎穴相接，哑门、风府、脑户、强间，后顶、百会、前顶依次排列在前上方。囟会靠近上星穴，神庭可见素髎之妙用，水沟穴直达兑端穴而无差错，龈交穴位于唇内可治疗疾病。
督脉的龈交穴在唇内深处，兑端穴正位于唇端夹缝处，水沟穴在鼻下沟中素髎下方，素髎穴宜向鼻端仔细辨认。头部形状北高南低，先以前后发际之间的距离来测量，分为一尺二寸。发际上五分处为神庭穴，发际上一寸处为上星穴，发际上二寸处为囟会穴，发际上前顶穴在三寸半处，发际上百会穴在五寸中央（位于头顶中央旋毛中，可容纳豆子，两耳尖连线与正中线的交点）。性理学家北溪陈氏说：略偏北一点如同天的极星，居北方。会后一寸半处是后顶穴，会后三寸处是强间穴，会后四寸半处是脑户穴，后发际入内一寸处是风府穴（项后发际入内一寸，大筋内的凹陷中），发上五分处是哑门穴（后发际上五分，项中央凹陷中，仰头取穴，深入联系舌根），从项骨至此共有十个穴位。自这项骨下的脊柱开始，分为二十四个椎体，大椎上有项骨存在，大约有三个椎体不计算在内，尾骨处的长强穴也不计算在内，中间二十一个椎体可以依次排列。大椎的大骨为第一个椎体，第二个椎节内有陶道穴，第三个椎间有身柱穴，第五椎间有神道穴不必怀疑，第六、第七椎间有灵台和至阳穴，第九椎间有筋缩穴，第十一椎间有脊中穴，第十二椎间有悬枢穴，第十四椎间有命门穴与肾俞穴并列，第十六椎间有阳关穴自然可知，第二十一个椎体即腰俞穴，脊尾骨端有长强穴跟随。（共二十七个穴位）
The Du Mai (Governing Vessel) runs along the midline of the back, starting with seventeen acupoints beginning at Changqiang (GV1). Following are Yaoshu (GV2), Yangguan (GV3), entering between Mingmen (GV4) and Xianshu (GV5), ascending along the spinal ligament to reach Zhiyang (GV9). Lingtai (GV10), Shendao (GV11), Shenzhu (GV12), Taodao (GV13) connect with Dazhui (GV14); Yameng (GV15), Fengfu (GV16), Naohu (GV17), Qiangjian (GV18), Houding (GV19), Baihui (GV20), and Qianding (GV21) are arranged successively in the upper anterior region. Xinhui (GV22) is close to Shangxing (GV23); Shenting (GV24) reveals the subtlety of Suxiao (GV26); Shuigou (GV26) reaches Duanduan (CV15) without error; Yinjiao (GV28) resides within the lip to treat diseases.
Yinjiao (GV28) of the Du Mai is deep within the lip; Duanduan (CV15) is located precisely at the tip of the lip. Shuigou (GV26) is in the groove below the nose beneath Suxiao (GV26); Suxiao (GV26) should be carefully identified towards the nasal tip. The head shape is higher in the north and lower in the south; first measure the distance between the anterior and posterior hairlines, dividing it into one chi and two cun. Five fen above the hairline is Shenting (GV24); one cun above is Shangxing (GV23); two cun above is Xinhui (GV22); three and a half cun above is Qianding (GV21); five cun above is Baihui (GV20) at the center (located in the central whorl of hair on the vertex, where a bean can fit, intersection of lines connecting ear tips and the midline). Chen Bixi, a scholar of Neo-Confucianism, stated: slightly closer to the north, like the Pole Star of heaven, residing in the north. One and a half cun behind Baihui is Houding (GV19); three cun behind is Qiangjian (GV18); four and a half cun behind is Naohu (GV17); entering one cun from the posterior hairline is Fengfu (GV16) (one cun inside the posterior hairline, within the depression of the large tendon); five fen above the hairline is Yameng (GV15) (five fen above the posterior hairline, in the depression of the center of the neck, take with head extended, entering to connect with the root of the tongue); there are ten true acupoints from this point down to the cervical vertebrae. From the cervical vertebrae downwards along the spine, there are twenty-four vertebrae in total. Above Dazhui (GV14), there are cervical vertebrae, approximately three which are not counted; Changqiang (GV1) at the tailbone is also not counted; the middle twenty-one vertebrae can be arranged sequentially. The great bone of Dazhui (GV14) is the first; Taodao (GV13) is known within the second vertebral segment; Shenzhu (GV12) is in the third intervertebral space; Shendao (GV11) is in the fifth, no need to doubt; Lingtai (GV10) and Zhiyang (GV9) are in the sixth and seventh; Jinsuo (GV9) is thought of in the ninth; Jizhong (GV11) is in the eleventh; Xianshu (GV5) is singular in the twelfth; Mingmen (GV4) and Shenshu (BL23) coincide at the fourteenth; Yangguan (GV3) is naturally known at the sixteenth; the twenty-first vertebra is Yaoshu (GV2); Changqiang (GV1) follows at the end of the sacrococcygeal bone. (Total twenty-seven acupoints)
This section does not mention the Du Mai and Ren Mai here; only later text mentions the distinction between Du Mai and Ren Mai, likely referring to the Luo-connecting points. Now attaching two diagrams here, so that the Fourteen Meridians are complete.
