左右两肾中间的一点真阳,是生命的根本。其中有相火代替心君行使功能,所以又被称为“小心”。
小肠:经文说小肠是受盛之官,负责消化食物并转化精微。又说小肠后方附着于脊柱前方,前方附着于脐上,向左盘绕累积十六个弯曲,直径二寸半,内径八分加上少半(即约八分多)。长度三丈二尺,能容纳谷物二斗四升,水六升三合(加上大半合)。又说小肠的上口在脐上二寸处,靠近脊柱,水谷由此进入;再向下延伸一寸,外部附着于脐部,此处为水分穴。到达这里时,小肠下口将清浊分开,水液渗入膀胱,糟粕流入大肠。又说这条经脉多血少气。《难经》记载小肠重三斤十四两。
大肠:经文说大肠是传道之官,负责传导变化。又说回肠位于脐部左侧,向左盘绕十六个弯曲,直径大四寸,内径一寸半,长度二丈一尺,能容纳谷物一斗,水七升半。又说广肠附着于脊柱以承接回肠,这是排出糟粕的通道,直径八寸,内径二寸半,长度二尺八寸,能容纳谷物九升三合八分之一。这条经脉多气少血。《难经》记载大肠重二斤十二两,肛门重十二两。张介宾说:按回肠之名,是因为它回叠盘曲;广肠即是比回肠更大的部分;直肠则是广肠的末端,向下连接肛门。
膀胱:经文说膀胱是州都之官,津液在此储藏,经过气化作用才能排出。又说膀胱位于第十九椎下方,肾脏之下,大肠之前,有下口而无上口。当脐上一寸的水分穴处是小肠的下口,也是膀胱的上际。水液由此别出,通过回肠随气化渗透而入。如果入的气化正常而出气不化,则水道闭塞,下窍不通,形成癃肿;如果出气不化而入气不化,则水液归入大肠导致泄泻。这条经脉多血少气。《难经》记载膀胱重九两二铢,纵广九寸,盛尿九升九合,口宽二寸半。
宗筋:肝之筋脉结聚于阴器,联络诸筋;脾胃之筋聚于阴器;肾之筋结于阴器。溺孔即前阴,是督脉起始之处。
毛际:宗筋之上,小腹之下,横骨之间的丛毛之处。任脉从会阴上行至毛际,冲脉起于气街(即气冲穴,属阳明经,位于毛际两旁)。阳明经气血旺盛则毛发美长,气血少则无毛。肝之筋脉进入毛际,胆之经脉环绕毛际。
睾丸:男子之外肾,位于宗筋之下的阴囊中,是两个丸状物。
篡(指会阴区域):横骨之下,两股之前相合共结的凹陷处。前后两阴之间,名为下极穴,又名屏翳穴、会阴穴,即男女阴气汇聚之所。
脑后骨:俗称脑杓。
枕骨:脑后骨之下隆起的部分。其形状有的呈棱形,有的平坦,有的长,有的圆,各不相同。
完骨:耳后的棱形骨,名为完骨,位于枕骨下方的两旁棱骨处。
颈项:颈的前部茎状部分称为颈,侧面称为颈侧,后面称为项。俗名脖项。颈前有缺盆穴,属胃经,位于横骨上方,左右各一,为十二经道路所在。大小肠、胃、胆、三焦的经脉都进入缺盆。肺、胃、胆、膀胱的筋脉都结聚于缺盆。缺盆之中即任脉的天突穴,为颈前居中第一行经脉。缺盆之上有人迎穴,喉间开一寸五分处,属胃经,即颈前第二行经脉。人迎穴后一寸五分名为扶突穴,属大肠经,即颈中第三行经脉。扶突穴后名为天窗穴,属小肠经,即颈中第四行经脉。天窗后为胆脉,颈中无穴,乃第五行经脉。足少阳脉后名为天牖穴,属三焦经,即颈中第六行经脉。天牖穴后名为天柱穴,属膀胱经,为颈中第七行经脉。颈之中央为督脉,穴名风府,自前中一行至此为第八行。
颈骨:头的茎骨,肩骨上际的骨,俗名天柱骨。
项骨:头后茎骨之上的第三节圆形骨。
背:后身大椎以下、腰以上的统称。
脊骨:即脊膂骨,俗名脊梁骨。督脉主司脊骨,大肠脉挟脊而行,心脉与脊里的细脉相连贯,脾筋附着于脊,肾筋脉贯穿脊,膀胱筋脉挟脊分左右上行至项。其分左右是从脊旁开一寸五分为第二行,对应第三椎曰肺俞,对第五椎曰心俞,对第七椎曰膈俞,对第九椎曰肝俞,对第十椎曰胆俞,对第十一椎曰脾俞,对第十二椎曰胃俞,对第十三椎曰三焦俞,对第十四椎曰肾俞,对第十六椎曰大肠俞,对第十八椎曰小肠俞,对第十九椎曰膀胱俞。从脊旁开三寸为第三行,魄门对肺俞,故肺藏魄;神堂对心俞,故心藏神;魂门对肝俞,故肝藏魂;意舍对脾俞,故脾藏意;志舍对肾俞,故肾藏志;膏肓对第四椎。
腋:肩之下、胁之上的边际,俗名胳肢窝。肺之筋脉进入腋,心和小肠之筋结于腋,胆之筋走腋,心包络脉抵腋。
胁肋:胁是腑下至肋骨尽处的总称。肋是指胁中的单条骨。总称胁肋,又名肝胆脉布于胁,胞络筋脉挟胁,脾筋结于肋,肝脉布于肋。
季胁:胁之下的小肋骨,俗名软肋。肺脉抵季胁,胆筋脉乘季胁。胁下无肋骨的空软处,胆脉乘之。
腰骨:即脊骨第十四椎下、第十五十六椎间的尻上之骨。形状中间凹,上宽下窄,方圆二三寸许。两旁有四孔,下接尻骨上际。肾脉入腰,膀胱脉抵腰。
胂:腰下两旁、踝骨上的肉。
臀:胂下、尻旁的大肉。膀胱脉贯穿臀部,筋结于臀。
尻:腰骨下第十七椎至第二十一椎五节之骨。上四节纹的旁边,左右各四孔。骨形内凹如瓦,长四五寸许,上宽下窄,末节更小如人参芦,名为尾闾,一名端,一名橛骨,一名穷骨。位于肛门后,其骨上外两旁形如马蹄,附着于两踝骨上端,俗名骶骨。胆筋结于尻。
肛:大肠的下口。肛门接直肠,直肠接大肠。大肠与肺为表里,肺气充足方能传送。
下横骨、髁骨、楗骨:下横骨在小腹下,形状如盖,故名盖骨。其骨左右两大孔,上两分出向后之骨首如张扇,下寸许附于尻骨之上形如马蹄之处名为髁骨。下两分出向前之骨末如楗柱,在于臀内,名为楗骨。与尻骨成鼎足之势,为坐的主骨。妇人俗名交骨。其骨面名为髋,侠髋之臼名为机,又名髀枢。外接股之髀骨也,即环跳穴处。此一处有五名。
股:下体两大支的统称,俗名大腿。小腿中节上下交接处名为膝。膝上的骨名为髀骨,是股的大骨。膝下的骨名为胫骨,是胫的大骨。股肉属脾,筋属肝,骨属肾。
髀骨:膝上的大骨。上端如杵接于髀枢,下端如锤接于胫骨。
胫骨:俗名胫骨。其骨两根,在前者名为成骨,又名巨骨,形粗,膝外突出。在后者名为辅骨,形细,膝内侧的小骨。
伏兔:髀骨前、膝之上,起肉似伏兔,故名。
膝解:膝的关节解处。膝属脾、肾、肝。凡人安逸则痿软无力,劳作则痛如针刺。脉洪数有力皆因肝肾阴虚火盛所致。痿软无力是真病的形态,作痛如锥是邪火的象。
髌骨:膝上盖骨。
连骸:膝外侧两个高骨。膝后屈处,俗名腿凹。
下腿肚:也称腓肠,俗名小腿肚,属足太阳膀胱经。
踝骨:踝者是胫骨之下、足附之上的两旁突出的高骨。在外为外踝,在内为内踝。
足:下体用来行走的部位,俗名脚。
跗骨:足背,一名足趺,俗称脚面。跗骨是足趾本节众多的骨头。
足心:即踵的中部。
跟骨:足后跟的骨。
三毛:足大指爪甲后为三毛,毛后横纹为聚毛。
踵:足下面着于地的部分,俗名脚底板。
足趾:趾是足的指,数量为五,名为趾是为了区别于手。大趾的本节后内侧圆骨形突者名为核骨。足大指外侧属肝,内侧属脾。脾之筋脉皆起于足大指的隐白穴,为脾井穴;溜于节后陷中的大都穴,为脾荥穴;于内侧核骨下的太白穴,为脾俞穴;循大指本节后一寸的公孙穴,为脾络穴;历内踝前三分陷中的商丘穴,为脾经穴;由足循经骨后结于膝内辅骨陷中的阴陵泉穴之次,为脾合穴。从此直上至阴股,结于髀箕门穴之次。臀下曰肝筋脉皆起于足大指外侧丛毛之际的大敦穴,为肝井穴;溜于大指缝中的行间穴,为肝荥穴;行跗上注于本节后二寸动脉中的太冲穴,为肝俞穴;结于内踝前一寸的中封穴之次,为肝经穴;循踝上五寸的蠡沟穴,为肝络穴;直上内辅骨下横纹尽处的曲泉穴,为肝合穴;上阴股的五里、阴廉之次。
(旧说)足中指属胃。胃筋起于中指内侧的厉兑穴,为胃井穴;溜于次指外侧陷中的内庭穴,为胃荥穴;后二寸陷谷穴,为胃俞穴;过于跗上去内庭五寸的冲阳穴,为胃原穴。故胃病则足跗肿痛,足中指不用。自足跗直上循足胫历腕上系草鞋处的解溪穴,为胃经穴;又历外踝上八寸的丰隆穴,为胃络穴;结于膝下三寸的三里穴,为胃合穴;上膝循伏兔,结于髀前膝上起肉处为伏兔,后为髀关。其脉自伏兔直下抵足跗入中指内间。其支者别跗上入大指间出其端。按足阳明经是足大指的次指,不是中指,必是传写之误。胃脉起于鼻之交中下行至陷谷。陷谷穴在足大指次指间本节后陷中,内庭穴在足大指次指外间陷中,厉兑穴在足大指次指之端去爪甲如韭叶。三穴明是次指,与中指不属。以此知中字之误。然则中指何属?经云:“足阳明之别,下膝三寸而别,以下入中指外间。”此支自膝下三寸循三里穴之外别行而下,入中指外间,与前之内庭、厉兑合。是中指亦属胃也。
足四指属胆。胆筋起足四指外端的窍阴穴之次,为胆井穴;指岐骨间有侠溪穴,为胆荥穴;侠溪上寸半有临泣穴,为胆俞穴;侠溪上四寸五分有邱墟穴,为胆原穴;外踝上四寸阳辅穴,为胆经穴;外踝上五寸光明穴,为胆络穴。循胫至膝外廉,下膝一寸阳陵泉穴,为胆合穴。从是上走髀,分为两岐,前者结伏兔,后者结于尻。直者上季胁。其脉自髀阳直下出膝外廉,循胫抵外踝,至足跗入第四指之间。其支者别跗上入大指,贯爪甲后三毛。故足少阳血气盛则胫毛长、外踝肥;血气少则胫无毛、外踝瘦。病则膝、胫、外踝及大节诸节皆痛。
足小指指下属肾,外侧属膀胱。肾之筋脉俱起小指之下,斜趋足心的涌泉穴,为肾井穴;又侧趋内侧,内一寸大骨下有然谷穴,为肾荥穴;结于跟踵(踵即跟之突出者,跟即踵上硬筋处),陷中有大溪穴,为肾俞穴;自跟别至跟后踵中大骨上两筋间有大钟穴,为肾络穴;踝上二寸复溜穴,为肾经穴;上出内廉,结于内辅骨下阴谷穴之次,为肾合穴。从是并大阴之筋上循阴股。膀胱筋起小指外侧去爪甲一分至阴穴之次,为膀胱井穴;历本节之前陷中有通谷穴,为膀胱荥穴;本节之后陷中有束骨穴,为膀胱俞穴;外侧大骨之下有京骨穴,为膀胱原穴;外踝后骨跟上有昆仑穴,为膀胱经穴;循跟直上至外踝上七寸有飞阳穴,为膀胱络穴;贯结于腘即委中,在膝脘内约纹中,为膀胱合穴。由腘直上结于臀。其脉从腰抵腘,出小指外侧。故膀胱病似结,如裂,足小指不能举用。
Between the left and right kidneys, a point of True Yang serves as the root of life. Within it, Ministerial Fire (Xiang Huo) acts on behalf of the Heart Sovereign, hence it is also called the "Lesser Heart" (Xiao Xin).
Small Intestine: The *Ling Shu* states, "The Small Intestine is the official of reception and transformation, responsible for separating the clear from the turbid." It further states, "The Small Intestine attaches posteriorly to the front of the spine and anteriorly above the umbilicus, looping leftward with sixteen curves. Its outer diameter is two cun and half, inner diameter eight fen plus one-third fen, and length three zhang and two chi. It can hold two dou and four sheng of grain, and six sheng and three he (plus half-he) of water." It also states, "The upper opening of the Small Intestine is two cun above the umbilicus, near the spine, where water and grain enter. One cun lower, externally attached to the umbilicus, is the Shuifen (Water Divider) acupoint. Here, at the lower opening of the Small Intestine, clarity and turbidity are separated; watery fluids seep into the Bladder, while dregs flow into the Large Intestine." It is stated that this meridian has abundant blood but scarce qi. The *Nan Jing* says, "The Small Intestine weighs three jin and fourteen liang."
Large Intestine: The *Ling Shu* states, "The Large Intestine is the official of transmission and passage, responsible for change and transport." It further states, "The Hui Chang (Looping Intestine) is located beside the umbilicus, looping leftward sixteen times. Its outer diameter is four cun, inner diameter one cun and half, and length two zhang and one chi. It can hold one dou of grain and seven sheng and half of water." It also states, "The Guang Chang (Broad Intestine) attaches to the spine to receive the Hui Chang; this is the pathway for expelling dregs. Its outer diameter is eight cun, inner diameter two cun and half, and length two chi and eight cun. It can hold nine sheng, three he, and one-eighth he of grain." This meridian has abundant qi but scarce blood. The *Nan Jing* says, "The Large Intestine weighs two jin and twelve liang, and the anus weighs twelve liang." Zhang Jiebin notes: "Regarding the Hui Chang, it is named so due to its looping folds; the Guang Chang is the larger portion of the Hui Chang; the Zhi Chang (Straight Intestine) is the terminal segment of the Guang Chang, connecting downward to the anus."
Bladder: The *Ling Shu* states, "The Bladder is the official of the provincial capital, storing fluids; only through Qi transformation can they be excreted." It further states, "The Bladder is located below the nineteenth vertebra, beneath the Kidneys and anterior to the Large Intestine. It has a lower opening but no upper opening. At the Shuifen acupoint, one cun above the umbilicus, which is the lower opening of the Small Intestine, lies the upper boundary of the Bladder. Fluids separate here, following the Qi transformation of the intestines to seep in. If incoming Qi fails to transform, water returns to the Large Intestine causing diarrhea; if outgoing Qi fails to transform, the lower orifices become blocked leading to strangury and swelling." This meridian has abundant blood but scarce qi. The *Nan Jing* says, "The Bladder weighs nine liang and two zhu, is nine cun long and wide, holds nine sheng and nine he of urine, and its opening is two cun and half wide."
Zong Jin (Tendon Sheath): The Liver tendon meridians knot at the Yin Qi (genital organ), connecting all tendons; Spleen and Stomach tendons gather at the Yin Qi; Kidney tendons knot at the Yin Qi. The urinary aperture is the anterior yin, the starting point of the Du Meridian.
Mao Ji (Hair Region): The area of clustered hair above the Zong Jin, below the lower abdomen, and between the transverse bone. The Ren Meridian ascends from Huiyin to the Mao Ji; the Chong Meridian originates at Qichong (which belongs to the Yangming Meridian), located on both sides of the Mao Ji. When Yangming Qi and Blood are abundant, hair is beautiful and long; when scarce, there is no hair. Liver tendons enter the Mao Ji, and Gallbladder meridians surround the Mao Ji.
Testicles: The external kidneys of men, located within the scrotum below the Zong Jin, consisting of two oval bodies.
Cuan (Perineal Depression): The concave area formed by the convergence of the fronts of the two thighs below the transverse bone. Located between the anterior and posterior yins, it is named Xiaji (Lower Pole), also known as Pingyi or Huiyin, the gathering place of Yin Qi for both men and women.
Hou Nao Gu (Posterior Head Bone): Commonly called Naoshao.
Zhen Gu (Occipital Bone): The raised bone below the posterior head bone. Its shape varies, being prismatic, flat, long, or round.
Wan Gu (Complete Bone): The prismatic bone behind the ear, named Wan Gu, located at the prismatic bones on both sides below the occipital bone.
Jing Xiang (Neck and Nape): The anterior part of the neck is called Jing, the side is called Jing, and the posterior part is called Xiang. Commonly referred to as Boxiang. In the anterior neck, the Quepen acupoint belongs to the Stomach Meridian, located above the transverse bone, one on each side, serving as the pathway for the twelve meridians. The meridians of the Large Intestine, Small Intestine, Stomach, Gallbladder, and Sanjiao enter the Quepen; the tendons of the Lung, Stomach, Gallbladder, and Bladder knot at the Quepen. Within the Quepen lies the Tiantu acupoint of the Ren Meridian, the first row of meridians centered in the anterior neck. Above the Quepen is the Yingtang acupoint, one cun and five fen open in the throat, belonging to the Stomach Meridian, the second row of meridians in the anterior neck. One cun and five fen posterior to Yingtang is the Futu acupoint, belonging to the Large Intestine Meridian, the third row of meridians in the neck. Posterior to Futu is the Tianchuang acupoint, belonging to the Small Intestine Meridian, the fourth row of meridians in the neck. Posterior to Tianchuang is the Gallbladder Meridian; there are no acupoints in the neck center, constituting the fifth row of meridians. Posterior to the Foot Shaoyang is the Tianyou acupoint, belonging to the Sanjiao Meridian, the sixth row of meridians in the neck. Posterior to Tianyou is the Tianzhu acupoint, belonging to the Bladder Meridian, the seventh row of meridians in the neck. The center of the neck is the Du Meridian, with the Fengfu acupoint; from the anterior central row to here constitutes the eighth row.

On the sides of the patterns of the upper four segments, there are four holes on each side. The bone shape is concave like a tile, about four to five cun long, wider at the top and narrower at the bottom, with the terminal segment smaller like the shoot of ginseng. It is named Weilu, also Duan, Jue Gu, or Qiong Gu, located posterior to the anus. The upper outer sides of this bone are horse-hoof shaped, attaching to the upper ends of the two malleoli, commonly called the sacrum. Gallbladder tendons knot at the kao.
Gang (Anus): The lower opening of the Large Intestine. The anus connects to the rectum, which connects to the Large Intestine. The Large Intestine and Lung are exterior-interior pairs; sufficient Lung Qi enables transportation.
Xia Heng Gu, Ke Gu, Jian Gu: The Xia Heng Gu (Transverse Bone) is below the lower abdomen, shaped like a lid, hence named Gaigu (Cover Bone). From its two large holes on the left and right, bones branch upward and backward; their heads resemble an open fan. About one cun down, attaching to the horse-hoof shaped part of the sacrum, is named Ke Gu. Branching downward and forward from the two lower divisions are bones ending like pillars within the buttocks, named Jian Gu. Together with the sacrum, they form a tripod posture, serving as the main bone for sitting. In women, commonly called Jiaogu. The surface of this bone is named Kua; the acetabulum beside Kua is named Ji, also Bisu. It connects externally to the femur, corresponding to the Huantiao acupoint. This location has five names.
Gu (Thigh): A general term for the two major supports of the lower body, commonly called thigh. The junction between the middle and upper/lower segments of the lower leg is named Xi (Knee). The bone above the knee is named Bigu, the major bone of the thigh. The bone below the knee is named Jinggu, the major bone of the shin. Thigh flesh belongs to the Spleen, tendons to the Liver, and bones to the Kidney.
Yin Gu (Medial Thigh): The medial side of the thigh is called Yin Gu. The tendons of the Spleen, Liver, and Kidney all circulate along the Yin Gu.

Futu (Rabbit Lying Down): The fleshy prominence anterior to the femur and above the knee, resembling a lying rabbit, hence the name.
Xi Jie (Knee Joint): The articulation of the knee. The knee belongs to the Spleen, Kidney, and Liver. Idleness leads to flaccidity and weakness; exertion leads to pain like needle pricking. A pulse that is洪数 (surging and rapid) indicates deficiency of Liver and Kidney Yin with hyperactive fire. Flaccidity and weakness represent the true disease form; pain like a cone represents the image of evil fire.
Bin Gu (Patella): The covering bone above the knee.
Lian Hai (Connecting Malleolus): The two high bones on the lateral side of the knee. The flexed area behind the knee is commonly called the popliteal fossa.

San Mao (Three Hairs): Behind the nail of the big toe are the Three Hairs; the transverse crease behind the hairs is Ju Mao.
Zhong (Heel): The part of the sole touching the ground, commonly called the sole of the foot.
Zu Zhi (Toes): Zhi refers to the fingers of the foot. There are five, named Zhi to distinguish them from hands. The rounded, prominent bone on the medial side behind the proximal joint of the big toe is named Hegu. The lateral side of the big toe belongs to the Liver; the medial side belongs to the Spleen. Spleen tendons originate from the Yinbai acupoint on the big toe, the Jing-Sea point of the Spleen; they flow into the Dadu acupoint in the depression behind the joint, the Ying-Spring point of the Spleen; at the Taibai acupoint below the medial Hegu, the Shu-Stream point of the Spleen; at the Gongson acupoint one cun behind the proximal joint of the big toe, the Luo-Connecting point of the Spleen; passing through the Shangqiu acupoint in the depression three fen anterior to the medial malleolus, the Jing-River point of the Spleen; circling behind the metatarsal bone, knotting in the depression below the medial accessory bone of the knee at Yinlingquan, the He-Sea point of the Spleen. From here, ascending straight to the Yin Gu, knotting near the Jimen acupoint, below the buttock.
Liver tendons originate from the cluster of hairs on the lateral side of the big toe at the Dadun acupoint, the Jing-Sea point of the Liver; flowing into the Xingjian acupoint in the gap between the big and second toes, the Ying-Spring point of the Liver; noting the Taichong acupoint in the arterial pulse two cun behind the proximal joint on the dorsum, the Shu-Stream point of the Liver; knotting at the Zhongfeng acupoint one cun anterior to the medial malleolus, the Jing-River point of the Liver; circulating up five cun from the ankle at the Ligou acupoint, the Luo-Connecting point of the Liver; straight up to the Ququan acupoint at the end of the transverse crease below the medial accessory bone, the He-Sea point of the Liver; ascending the Yin Gu to the Wuli and Yinlian acupoints.
(Old Theory) The middle toe of the foot belongs to the Stomach. Stomach tendons originate from the medial side of the middle toe at the Lidui acupoint, the Jing-Sea point of the Stomach; flowing into the Neiting acupoint in the depression on the lateral side of the second toe, the Ying-Spring point of the Stomach; two cun posteriorly at the Xiegu acupoint, the Shu-Stream point of the Stomach; crossing the dorsum, five cun distal to Neiting at the Chongyang acupoint, the Yuan-Source point of the Stomach. Thus, stomach diseases cause swelling and pain in the dorsum of the foot and dysfunction of the middle toe. Ascending straight from the dorsum along the shin, passing the Jiexi acupoint at the ankle crease where sandals tie, the Jing-River point of the Stomach; again passing the Fenglong acupoint eight cun above the lateral malleolus, the Luo-Connecting point of the Stomach; knotting at the Zusanli acupoint three cun below the knee, the He-Sea point of the Stomach; ascending the knee, circulating the Futu, knotting at the Bi. The fleshy prominence anterior to the hip and above the knee is Futu; posteriorly is Biguan. The meridian descends straight from Futu to the dorsum of the foot, entering the space between the middle toe. Its branch diverges from the dorsum, enters the big toe, and emerges at its tip. Note: The Foot Yangming Stomach Meridian belongs to the second toe (index toe), not the middle toe; this must be a transcription error. The Stomach Meridian originates at the intersection of the nose, descending to Xiegu. Xiegu is in the depression behind the proximal joint between the big and second toes; Neiting is in the depression on the lateral side between the big and second toes; Lidui is at the tip of the big and second toes, three grains of rice width from the nail. These three acupoints clearly belong to the second toe, not the middle toe. This confirms the error of the character 'Zhong' (middle). Then what does the middle toe belong to? The *Ling Shu* states: "The Foot Yangming Stomach Meridian... divides three cun below the knee, descending to enter the lateral space of the middle toe." This branch diverges three cun below the knee, circulating outside the Zusanli acupoint, descending to enter the lateral space of the middle toe, merging with the previous Neiting and Lidui. Thus, the middle toe also belongs to the Stomach.
The fourth toe belongs to the Gallbladder. Gallbladder tendons originate from the lateral end of the fourth toe at the Xiaolin acupoint, the Jing-Sea point of the Gallbladder; between the interphalangeal bones is the Xiaxi acupoint, the Ying-Spring point of the Gallbladder; one cun and half above Xiaxi is the Linqi acupoint, the Shu-Stream point of the Gallbladder; four cun and five fen above Xiaxi is the Qiuxu acupoint, the Yuan-Source point of the Gallbladder; four cun above the lateral malleolus is the Yangfu acupoint, the Jing-River point of the Gallbladder; five cun above the lateral malleolus is the Guangming acupoint, the Luo-Connecting point of the Gallbladder. Circulating along the tibia to the lateral aspect of the knee, one cun below the knee is the Yanglingquan acupoint, the He-Sea point of the Gallbladder. From here ascending to the thigh, dividing into two branches: the anterior branch knots at Futu; the posterior branch knots at the Kao. The straight branch ascends to the Ji Xie. The meridian descends straight from Bi Yang, exiting the lateral aspect of the knee, circulating along the tibia to the lateral malleolus, reaching the dorsum of the foot, entering the space between the fourth toes. Its branch diverges from the dorsum, enters the big toe, passes behind the nail through the Three Hairs. Therefore, when Qi and Blood of the Foot Shaoyang are abundant, leg hair is long and the lateral malleolus is plump; when scarce, there is no leg hair and the lateral malleolus is thin. Disease causes pain in the knee, tibia, lateral malleolus, and various joints.
The little toe belongs to the Kidney on the plantar side and to the Bladder on the lateral side. Kidney tendons originate below the little toe, slanting toward the center of the foot at the Yongquan acupoint, the Jing-Sea point of the Kidney; again slanting medially, one cun inside the large bone below the Ran Gu acupoint, the Ying-Spring point of the Kidney; knotting at the Gen Zhong (heel prominence), where the depression contains the Taixi acupoint, the Shu-Stream point of the Kidney. Diverging from the heel to the posterior aspect of the heel, between the two tendons above the large bone of the calcaneus, is the Dazhong acupoint, the Luo-Connecting point of the Kidney; two cun above the ankle is the Fuliu acupoint, the Jing-River point of the Kidney; ascending out the medial margin, knotting below the medial accessory bone at the Yin Gu acupoint, the He-Sea point of the Kidney. From here joining the Great Yin tendons, ascending along the Yin Gu. Bladder tendons originate from the lateral side of the little toe, one fen from the nail at the Zhiyin acupoint, the Jing-Sea point of the Bladder; passing through the depression anterior to the proximal joint at the Tonggu acupoint, the Ying-Spring point of the Bladder; through the depression posterior to the proximal joint at the Shugu acupoint, the Shu-Stream point of the Bladder; below the large bone on the lateral side at the Jinggu acupoint, the Yuan-Source point of the Bladder; behind the lateral malleolus on the heel at the Kunlun acupoint, the Jing-River point of the Bladder; circulating straight up the heel to seven cun above the lateral malleolus at the Feiyang acupoint, the Luo-Connecting point of the Bladder; penetrating and knotting at the Wei Zhong (Popliteal Crease), the He-Sea point of the Bladder. Ascending straight from Wei Zhong, knotting at the buttocks. The meridian descends from the waist to the popliteal fossa, exiting the lateral side of the little toe. Therefore, Bladder disease presents as feeling tied or torn, with inability to lift the little toe.
