（面旁也，在耳下，亦名蕃）属足少阳胆经、手阳明大肠之会（《灵枢》曰∶蕃者，
颊侧也；蔽者，耳门也。又曰∶足少阳之脉，下耳后，合手少阳，抵于 ，下加颊车。沈承之曰∶曲颊前寸许，
属手阳明大肠；曲颊后，属足少阳胆经）。又属手少阳三焦经、太阳小肠经（《灵枢》曰∶手少阳之筋，上肩，
走头，合手太阳。其支者，当曲颊，入系舌本。又曰∶足少阳在耳下曲颊之后。手少阳出耳后，上结完骨之上。
又曰∶手太阳当曲颊）。兼属足阳明胃经（《灵枢》曰∶足阳明之脉，循颐后下廉，出大迎，循颊车入耳前）。
（颐， 也，亦作颔）属足阳明胃
经（《灵枢》曰∶ 痛，刺足阳明曲周动脉，见血立已。《素问》曰∶阳明虚，则寒栗鼓颔，终则口耳动作。
又曰∶病上冲喉者，治其渐，渐者，上挟颐也。王启玄曰∶阳明之脉，渐上颐而环唇，故名挟颐为渐，即大迎
穴也。在曲颊下一寸三分，骨陷中动脉）。又属手少阳三焦经、阳明大肠经（《灵枢》曰∶手少阳之别者，上
挟咽，出颐 中。又曰∶ 痛，刺手阳明，与 之盛脉出血）。兼属足少阴肾经。（《素问》曰∶肾热病者，
颐先赤）
（在鼻下，即水沟穴之分也）属手足阳明大肠、胃经、督脉之会（《灵枢》曰∶手阳明
之脉，其支者，出挟口，交人中，左之右，右之左，上挟鼻孔。又曰∶足阳明之脉，循鼻外，入上齿中。沈承
之曰∶挟人中两旁五分，名禾 穴，属手阳明经）。又属足太阴脾经（《灵枢》曰∶足太阴气绝者，则脉不荣
肌肉。唇舌者，肌肉之本也。脉不荣，则肌肉软。肌肉软，则舌萎，人中满。人中满，则唇反。唇反者，肉先
死，甲笃乙死，木胜土也。《玄珠》曰∶人中肿者，脾绝也）。
（曲颊位于面部两侧，在耳朵下方，也叫做“蕃”。）这里是足少阳胆经和手阳明大肠经的交会处。（《灵枢》说：所谓“蕃”，是指脸颊侧面；所谓“蔽”，是指耳门。又说：足少阳胆经的经脉，下行经过耳后，与手少阳三焦经汇合，抵达下颌角附近，向下经过颊车穴。沈承之说：曲颊前方约一寸处，属于手阳明大肠经；曲颊后方，属于足少阳胆经。）这里又属于手少阳三焦经和太阳小肠经。（《灵枢》说：手少阳三焦经的筋脉，上行至肩部，走向头部，与手太阳小肠经汇合。其分支，正当曲颊处，进入并联系舌根。又说：足少阳胆经在耳下曲颊的后方。手少阳三焦经出于耳后，向上结聚于完骨之上。又说：手太阳小肠经正当曲颊处。）同时也兼属足阳明胃经。（《灵枢》说：足阳明胃经的经脉，沿着下颌后缘下行至下颌角，出于大迎穴，沿着颊车穴进入耳前。）
（颐，即下巴颏，也写作“颔”。）这里属于足阳明胃经。（《灵枢》说：如果下巴疼痛，针刺足阳明胃经在下颌弯曲处的动脉，见血出则疼痛立即停止。《素问》说：阳明经气虚弱，就会出现发冷颤抖、下巴鼓动，最终导致口眼歪斜抽动。又说：病邪向上冲逆喉咙的，治疗其起始部位，“渐”这个部位，是向上夹持下巴的地方。王启玄解释说：阳明经的经脉，向上到达下巴并环绕嘴唇，所以称夹持下巴为“渐”，这就是大迎穴。它位于曲颊下方一寸三分，在骨骼凹陷处的动脉中。）这里又属于手少阳三焦经和手阳明大肠经。（《灵枢》说：手少阳三焦经的别络，向上夹持咽喉，出于下巴中间。又说：下巴疼痛，针刺手阳明大肠经，以及该处充盛的脉络放血。）同时也兼属足少阴肾经。（《素问》说：患肾热病的人，下巴先发红。）
（人中位于鼻子下方，是水沟穴所在的部位。）这里是手足阳明大肠经、胃经以及督脉的交会处。（《灵枢》说：手阳明大肠经的支脉，从嘴角出来，交叉于人中部，左侧交叉到右侧，右侧交叉到左侧，向上夹持鼻孔。又说：足阳明胃经的经脉，沿着鼻外侧下行，进入上齿中。沈承之说：在人中两旁五分处，名为禾髎穴，属于手阳明大肠经。）这里又属于足太阴脾经。（《灵枢》说：足太阴脾经的气血断绝时，经脉就不能滋养肌肉。嘴唇和舌头是肌肉的根本。经脉不能滋养，肌肉就会软弱。肌肉软弱，舌头就会萎缩，人中部位饱满肿胀。人中饱满肿胀，嘴唇就会翻卷外翻。嘴唇翻卷外翻，说明肌肉已经先死亡，甲日病情加重乙日死亡，这是因为木克土所致。《玄珠》说：人中部位肿胀，是脾脏之气绝灭的表现。）
(Qujia is located on the sides of the face, below the ears, and is also known as "Fan".) This area is the intersection of the Foot-Shaoyang Gallbladder Meridian (Zu Shao Yang Dan Jing) and the Hand-Yangming Large Intestine Meridian (Shou Yangming Da Chang Jing). (*Ling Shu* states: "Fan" refers to the lateral side of the cheek; "Bi" refers to the ear gate. It further states: The meridian of the Foot-Shaoyang Gallbladder descends behind the ear, converges with the Hand-Shaoyang Sanjiao Meridian, reaches the angle of the mandible, and descends past Jiache acupoint. Shen Chengzhi notes: Approximately one cun anterior to Qujia belongs to the Hand-Yangming Large Intestine Meridian; posterior to Qujia belongs to the Foot-Shaoyang Gallbladder Meridian.) This area also pertains to the Hand-Shaoyang Sanjiao Meridian (Sanjiao Meridian) and the Hand-Taiyang Small Intestine Meridian (Small Intestine Meridian). (*Ling Shu* states: The sinews of the Hand-Shaoyang Sanjiao ascend to the shoulder, travel to the head, and converge with the Hand-Taiyang Small Intestine Meridian. Its branch lies at Qujia, entering to connect with the root of the tongue. It further states: The Foot-Shaoyang is posterior to the curved jaw below the ear. The Hand-Shaoyang emerges from behind the ear and ascends to knot above Wangu bone. It further states: The Hand-Taiyang corresponds to Qujia.) It also concurrently belongs to the Foot-Yangming Stomach Meridian (Stomach Meridian). (*Ling Shu* states: The meridian of the Foot-Yangming Stomach follows the posterior margin of the mandible, descends to the lower border, emerges at Daying acupoint, follows Jiache acupoint, and enters anterior to the ear.)
(Yi, referring to the chin or mental region, is also written as "Han".) This area belongs to the Foot-Yangming Stomach Meridian. (*Ling Shu* states: If there is pain in the chin, puncture the arterial pulse at the curved part of the Foot-Yangming; upon bleeding, the pain ceases immediately. *Su Wen* states: When the Yangming Qi is deficient, there will be cold chills and trembling of the chin, eventually leading to movements of the mouth and ears. It further states: For pathogenic factors rushing upward to the throat, treat the starting point; this starting point, called 'Jian', is located superiorly clamping the chin. Wang Qixuan explains: The Yangming meridian ascends to the chin and encircles the lips, hence the term 'clamping the chin' as 'Jian', which refers to Daying acupoint. It is located 1.3 cun below Qujia, within the bony depression where the arterial pulse is felt.) This area also pertains to the Hand-Shaoyang Sanjiao Meridian and the Hand-Yangming Large Intestine Meridian. (*Ling Shu* states: The divergent channel of the Hand-Shaoyang ascends to clamp the pharynx and emerges from the middle of the chin. It further states: For chin pain, puncture the Hand-Yangming and bleed the full vessels in that area.) It also concurrently belongs to the Foot-Shaoyin Kidney Meridian (Kidney Meridian). (*Su Wen* states: In patients with Kidney Heat Disease, the chin turns red first.)
(Renzhong is located below the nose, corresponding to the location of Shuigou acupoint.) This area is the intersection of the Hand-Yangming Large Intestine Meridian, Foot-Yangming Stomach Meridian, and the Du Mai (Governing Vessel). (*Ling Shu* states: The branch of the Hand-Yangming Large Intestine Meridian emerges from beside the mouth, crosses at Renzhong, with the left crossing to the right and the right crossing to the left, ascending to clamp the nostrils. It further states: The meridian of the Foot-Yangming Stomach follows the lateral aspect of the nose and enters the upper teeth. Shen Chengzhi notes: Five fen on both sides of Renzhong is named Heliao acupoint, belonging to the Hand-Yangming Meridian.) This area also pertains to the Foot-Taiyin Spleen Meridian (Spleen Meridian). (*Ling Shu* states: When the Qi of the Foot-Taiyin Spleen is exhausted, the meridians fail to nourish the muscles. The lips and tongue are the roots of the muscles. If the meridians fail to nourish, the muscles become soft. Soft muscles lead to a flaccid tongue and fullness in Renzhong. Fullness in Renzhong leads to everted lips. Everted lips indicate that the flesh has died first; the condition worsens on Jia days and death occurs on Yi days, due to Wood overcoming Earth. *Xuan Zhu* states: Swelling in Renzhong indicates the exhaustion of Spleen Qi.)
