（前阴、后阴之间，会阴穴分也）
属任脉别络，挟督脉、冲脉之会（《素问》曰∶下阴别一。注∶下阴，即会阴穴也，是任脉别络，挟督脉、冲
脉之会，故曰下阴别一也。又曰∶屏翳两筋间，为篡内深处，即下极之俞，是督脉之起处。又曰∶督脉之络，
循阴器，合篡间，绕篡后）。
（股外骨也）属足少阳胆经（《灵枢》曰∶足少阳之筋，其支者，别起外辅骨，上走髀。
又曰∶足少阳之脉，过季胁，下合髀厌中，以下循髀阳）。〔前廉〕属足阳明胃经（《灵枢》曰∶足阳明之筋，
循伏兔上结于髀枢，其病转筋，髀前肿。《素问》曰∶胃脉搏坚而长，其色赤，当病折髀）。〔后廉〕属足太
阳膀胱经（《灵枢》曰∶足太阳脉，是动则病髀不可以曲）。兼属足太阴脾经（《灵枢》曰∶足太阴之筋，循
阴股结于髀，其病阴股引髀而痛。又曰∶脾有邪，其气留于两髀）。
〔中间〕（髀之内也）属足厥阴肝经（《灵枢》曰∶足厥阴之脉，上 内廉，循股阴，入
毛际中）。〔前廉〕属足太阴脾经〔后廉〕属足少阴肾经（《灵枢》曰∶足太阴之脉，循胫骨后，交出厥阴之
前，上膝股内前廉。又曰∶足少阴之脉，出 内廉，上股内后廉。所生病者，股内后廉痛。又曰∶肾胀者腹满，
引背央央然，腰痹痛）。
（位于前阴与后阴之间，是会阴穴的分界处）
属于任脉的别络，是挟持督脉和冲脉交汇之处。（《素问》说：下阴别一。注解说：下阴，就是会阴穴，它是任脉的别络，也是挟持督脉、冲脉的交会点，所以称为“下阴别一”。又说：屏翳在两筋之间，为篡内深处，即下极之俞，是督脉的起始处。又说：督脉的络脉，循行经过阴器，合于篡间，环绕篡后）。
（指股外侧的骨骼）属于足少阳胆经（《灵枢》说：足少阳经的筋，其分支，从外辅骨处分出，向上走行至髀部。又说：足少阳经的经脉，经过季胁，向下汇合于髀厌中，沿髀阳下行）。〔大腿前侧〕属于足阳明胃经（《灵枢》说：足阳明经的筋，循行伏兔穴上方结聚于髀枢，发病时出现转筋，大腿前部肿胀。《素问》说：胃脉搏动坚实而长，面色赤红，应当发生折髀病）。〔大腿后侧〕属于足太阳膀胱经（《灵枢》说：足太阳经脉发生变动，则病症表现为大腿不能弯曲）。兼属足太阴脾经（《灵枢》说：足太阴经的筋，循行阴股结聚于髀部，发病时阴股牵引髀部疼痛。又说：脾有邪气，其气停留于两髀）。
〔大腿内侧中间〕（指髀的内侧）属于足厥阴肝经（《灵枢》说：足厥阴经脉，上行至内廉，循行股阴，进入毛际之中）。〔大腿内侧前侧〕属于足太阴脾经〔大腿内侧后侧〕属于足少阴肾经（《灵枢》说：足太阴经脉，循行胫骨后方，交出在厥阴之前，上行至膝股内前侧。又说：足少阴经脉，出于内踝上廉，上行至股内后侧。所发生的疾病，包括股内后侧疼痛。又说：肾胀的症状是腹部满闷，牵引背部感觉不适，腰部痹痛）。
(Between the anterior and posterior orifices, this is the division of the Huiyin acupoint)
It belongs to the collateral branch of the Ren Mai (Conception Vessel), serving as the convergence point where the Du Mai (Governing Vessel) and Chong Mai (Penetrating Vessel) meet. (*Su Wen* states: "The lower yin separates into one." The commentary notes: "Lower yin" refers to the Huiyin acupoint; it is the collateral branch of the Ren Mai and the meeting point of the Du Mai and Chong Mai, hence called "lower yin separates into one." It further states: "Pingyi lies between two tendons, in the deep interior of the crotch, which is the Shu point of Xiaji, the starting point of the Du Mai." It also states: "The collateral of the Du Mai follows the genitalia, converges at the crotch, and circles behind the crotch.")
(Referring to the lateral bone of the thigh) It belongs to the Foot-Shaoyang Gallbladder Meridian (*Ling Shu* states: "The sinews of the Foot-Shaoyang have a branch that arises separately from the lateral auxiliary bone and ascends to the thigh." It also states: "The meridian of the Foot-Shaoyang passes through the costal region, descends to converge in the hip joint, and follows down along the lateral aspect of the thigh.") [Anterior margin] belongs to the Foot-Yangming Stomach Meridian (*Ling Shu* states: "The sinews of the Foot-Yangming follow the Futu area and knot at the hip pivot; when diseased, they cause muscle twitching and swelling in the anterior thigh. *Su Wen* states: "If the stomach pulse is firm and long, and the complexion is red, the patient should suffer from broken hip disease.") [Posterior margin] belongs to the Foot-Taiyang Bladder Meridian (*Ling Shu* states: "When the meridian of the Foot-Taiyang undergoes change, the disease manifests as an inability to flex the thigh.") It also relates to the Foot-Taiyin Spleen Meridian (*Ling Shu* states: "The sinews of the Foot-Taiyin follow the medial thigh and knot at the thigh; when diseased, pain radiates from the medial thigh to the thigh. It also states: 'When the spleen has pathogenic factors, their qi remains in both thighs'.)
[Medial center of the thigh] (Referring to the inner aspect of the thigh) belongs to the Foot-Jueyin Liver Meridian (*Ling Shu* states: "The meridian of the Foot-Jueyin ascends to the medial margin, follows the medial aspect of the thigh, and enters the pubic region.") [Anterior-medial margin] belongs to the Foot-Taiyin Spleen Meridian [Posterior-medial margin] belongs to the Foot-Shaoyin Kidney Meridian (*Ling Shu* states: "The meridian of the Foot-Taiyin follows behind the tibial bone, crosses out anterior to the Jueyin, and ascends to the anterior-medial margin of the knee and thigh. It also states: 'The meridian of the Foot-Shaoyin emerges from the medial malleolus, ascends along the posterior-medial margin of the thigh. Diseases generated include pain along the posterior-medial margin of the thigh.' It also states: 'Kidney distension presents with abdominal fullness, pulling sensation in the back, and lumbosacral bi-pain'.")
