Stomach Primary Channel

Chinese: 足阳明胃经

Pinyin: Zú Yáng Míng Wèi Jīng

Stomach Primary Channel

Pathway for Stomach Primary Channel

The internal pathway: 

  • The Stomach Primary Channel originates at Yingxiang LI-20 at the lateral side of the nose. It is also the Yang axes connection of the first great circuit of Hand and Foot Yang-Ming. 
  • It then runs to Jingming BL-1 at the inner eye canthus, where it crosses the Bladder Channel
  • Descending laterally along the infraorbital ridge, it reaches Chengqi ST-1, where the Channel emerges externally under the eyes. 

The external pathway: 

  • The Channel descends along the nose, enters the upper gum and meets Governing Vessel at Renzhong DU-26, above the midpoint of the philtrum. 
  • It then curves around the lips and intersects Directing Vessel at Chenjiang REN-24 in the center of the mentolabial groove. 
  • After crossing the lower cheek laterally, it reaches Daying ST-5 at the angle of the mandible. 
  • Continuing descending the neck along the anterior border of the sternocleidomastoid muscle, it arrives at Quepen ST-12 of the supraclavicular fossa. 
  • From ST-12, it continues descending, passes the nipples along the mamillary line, until Rugen ST-18, which is 1 intercostal space below nipple and 4 cun lateral to the midline. 
  • From ST-18, the Channel gets closer to the midline (2 cun), continues going downwards and bypasses umbilics to Qichong ST-30 in the inguinal region.  
  • From there, it curves and runs down further to Biguan ST-31 on the antero-lateral aspect of the thigh. 
  • It continues descending along the lateral margin of the femur to the knee and then alongside the lateral margin of the tibia to the dorsum of the feet. 
  • It finally terminates at Lidui ST-45 on the lateral corner of the second toe nail. 


  • One external branch separates from Daying ST-5 in the lower angle of the mandible. It ascends and passes Xiaguan ST-7 in front of the ear. Continuing ascending to Touwei ST-8 of the temporal region, it passes the forehead and finally terminates at Shenting DU-24 of the anterior midline. 
  • From Quepen ST-12 of the supraclavicular fossa, one internal branch crosses the shoulder to Dazhui DU-14, below the 7th cervical vertebra of spinous process (C7). This is also the place the Channel meets the other five Yang Primary Channel. 
  • From Quepen ST-12, an internal branch descends through diaphragm and passes the Stomach and the Spleen (its paired Zang and Fu Organ). Its minor subbranches link to Shangwan REN-13, Zhongwan REN-12 and Xiawan REN-10 of the Directing Vessel. This branch rejoin the main external Channel around Qichong ST-30 in the inguinal region. 
  • From Zusanli ST-36 slightly below the knee, an internal branch separates from the Primary Channel. It runs downwards to the lateral aspect of the middle tow. 
  • Another internal branches starts from Chongyang ST-42 on the dorsum of the foot. It flows to Yinbai SP-1 on the medial aspect of the big toe and forms the Foot Yin-Yang connection of the first great circuit. 

Stomach Divergent Channel

Chinese: 足阳明经别

Pinyin: Zú Yáng Míng Jīng Bié

Stomach Divergent Channel

Pathway for Stomach Divergent Channel

  • The Stomach Divergent Channel separates from the Primary Channel at Biguan ST-31 in the middle and anterior-lateral aspect of the thigh. 
  • It runs externally to Qichong ST at the inguinal region, where the Channel goes internally. 
  • Continuing ascending to the Stomach and spreading in the Spleen, it then goes up further and through the Heart
  • It then ascends along the oesophagus to Quepen ST-12 at the suprasternal fossa. 
  • Afterwards, it ascends along the neck to Renying ST-9 at the anterior border of the sternocleidomastoid muscle, where it meets its Primary Channel and the Spleen divergent Channel
  • It then runs up further to the mouth and nose, arriving at the inner eye canthus.
  • From there it curves around the eye to Chengqi ST-1, where it meets the Stomach Primary Channel. 

Stomach Sinew Channel

Chinese: 足阳明经筋

Pinyin: Zú Yáng Míng Jīng Jīn

Stomach Sinew Channel

Pathway for Stomach Sinew Channel

  • The Stomach Sinew Channel originates from the middle three toes. 
  • It spreads crossing the foot dorsum and binds at the tibial depression. It then separates into two branches:
    • One branch runs up along the anterolateral aspect of the leg, knee and thigh. During the journey, it binds at the lateral aspect of the knee and hip joint. It then passes through the lateral abdomen and spreads across the lower ribs to the spine. 
    • The other branch runs along the tibia and binds at the anterior aspect of the knee. 
      • A  short subbranch flows to the fibula head and connects to Gall Bladder Sinew Channel at Yuanglingquan GB-34 on the knee.
      • Ascending further along the anterior aspect of the thigh, the main branch binds in the pelvic region above the genitals at Qugu REN-2 and Zhongji REN-3
      • It then runs further up across the abdomen as well as chest, binding at Quepen ST-12 in the supraclavicular fossa. 
      • Continuing ascending along the anterolateral aspect of the neck, it binds at the angle of the mandible.
      • From there, it divides into three subbranches: 
        • One subbranch terminates  and binds in front of the ear. 
        • Another subbranch ascends to the mouth and binds besides the nose. Ascending further along nose, it connects to the Bladder Sinew Channel and creates a muscular neck below the eye. 
        • The third subbranch runs up to Quanliao SI-18 at the zygomatic bone, where it connects to the other Yang Sinew Channels. 

Stomach Luo-Connecting Vessel System

Chinese: 足阳明络脉

Pinyin: Zú Yáng Míng Luò Mài

Stomach Luo-Connecting Vessel System

Pathway for Stomach Luo-Connecting Vessel System

  • Stomach Luo-Connecting Vessel separates from the Primary Channel at Fenglong ST-40, on the lateral side of the lower leg. 
  • From there it forms a three-dimensional reticular network composed of various branches and subbranches. 
    • One branch connects with the Spleen Primary Channel interiorly and exteriorly.
    • The main branch ascends along the anterolateral aspect of the leg and torso to Quepen ST-12 in the supraclavicular fossa. It then divides into two subbranches: 
      • One crosses to the neck and terminates there. 
      • The other one ascends to the head, through occiput, and terminates at Baihui DU-20 of the vertex.
