Gall Bladder Primary Channel

Chinese: 足少阳胆经

Pinyin: Zú Shǎo Yáng Dǎn Jīng

Gall Bladder Primary Channel

Pathway for Gall Bladder Primary Channel

The external pathway: 

  • The Kidney Primary Channel originates at Tongziliao GB-1 at the outer canthus of the eye. It connects to Sizhukong TB-23 of the Triple Burner Channel through a small branch and they forms the Hand-Foot pairing of the third great circuit. 
  • It then flows to Tinghui GB-2 in front of the ear and then ascends to Shangguan GB-3 at upper border of the zygomatic arch. 
  • After reaching Hanyan GB-4 at the forehead corner, it descends and passes Xuanlu GB-5, Xuanli GB-6 and Qubin GB-7 above the ear. 
  • It then curves posteriorly behind the ear to Wangu GB-12 at the mastoid process below the ear. 
  • From there, the Channel travels all the way to Yangbai GB-14 above the supraorbital region on the forehead corner though the lateral side of the head. 
  • It then ascends and curves along the side of the head again to Fengchi GB-20 below the occiput. 
  • Afterwards, it descends and reaches Jianjing GB-21 on top of the shoulder. 
  • From there, the Channel went internally and emerges again at Quepen ST-12 at the supraclavicular fossa.
  • From ST-12, it descends to  the anterior aspect of the axilla and passes Yuanye GB-22, Zhejin GB-23 and Riyue GB-24 along the lateral thoracic wall.
  • It then passes Jingmen GB-25 at the lower border of the free end of the 12th rib. 
  • Continues descending diagonally to Juliao GB-29 around hip, it then runs laterally to Huantiao GB-30 on the buttock. This is also the point the internal and external pathway meets. 
  • The external Channel continues going down the lateral aspect of the thigh, knee and lower leg to the anterior aspect of the lateral malleolus. 
  • From there, it crosses the foot dorsum along the depression between the 4th and 5th metatarsal bones.  
  • It terminates at Zuqiaoyin GB-44 at the ulnar corner of the forth toe nail. 

The internal pathway: 

Branches: 

Gall Bladder Divergent Channel

Chinese: 足少阳经别

Pinyin: Zú Shǎo Yáng Jīng Bié

Gall Bladder Divergent Channel

Pathway for Gall Bladder Divergent Channel

  • The Gall Bladder Divergent Channel separates from the Primary Channel near Huantiao GB-30 on the buttock. Some books say the thigh is the origin. 
  • It crosses the hip area, enters the pubic hairline, crosses the Liver Divergent Channel and reaches Qugu REN-2 of the midline. 
  • It then ascends diagonally through the abdomen to Zhangmen LIV-13 below the free end of the 11th rib, where the Divergent Channel goes internally. 
  • It enters the flank between the lower ribs and connects with the Gall Bladder and the Liver
  • After passing the Heart and esophagus, it ascends the neck and emerges at the lower jaw. 
  • It then disperses on the face and meets the Gall Bladder Primary Channel at the outer canthus of the eye. 
  • It links to the eye system and terminates in the Brain. 

Gall Bladder Sinew Channel

Chinese: 足少阳经筋

Pinyin: Zú Shǎo Yáng Jīng Jīn

Gall Bladder Sinew Channel

Pathway for Gall Bladder Sinew Channel

  • The Gall Bladder Sinew Channel starts at the 4th toe and binds around Qiuxu GB-40 at the lateral malleolus. 
  • It then ascends along the lateral aspect of the leg and binds at the the lateral aspect of the knee and fibula. 
    • A branch crosses obliquely to Futu ST-32 on the anterior aspect of the thigh and binds there. 
  • The main Channel ascends further and binds at the hip.
    • From there, an other branch separates and disperses over the gluteal and sacral area. 
  • The main Channel continues ascending the flank to the lower costal region. It then divides into two branches: 
    • One branch crosses the lateral aspect of the chest to the breast and then ascends to bind at Quepen ST-12 in the supraclavicular fossa. 
    • The other one follows the midaxillary line to Quepen ST-12, where it rejoins the other branch. 
  • From Quepen ST-12, the Sinew Channel runs up further the lateral aspect neck, curves around the ear to the temple and then ascends to Baihui DU-20 at the vertex, where it meets its bilateral counterpart. 
    • One branch separates from the temple, crosses the zygomatic arch to Quanliao SI-18, where it meets with the other Foot Yang Sinew Channels. 
      • From there, a subbranch runs to the side of the nose and binds there. 
      • The other subbranch ascends to bind at the outer canthus. 

Gall Bladder Luo-Connecting Vessel System

Chinese: 足少阳络脉

Pinyin: Zú Shǎo Yáng Luò Mài

Gall Bladder Luo-Connecting Vessel System

Pathway for Gall Bladder Luo-Connecting Vessel System

  • Gall Bladder Luo-Connecting Vessel System separates from the Primary Channel at Guangming GB-37, on the lateral aspect of the lower leg. 
  • From there it forms a three-dimensional reticular network composed of various branches and subbranches. 
    • The main branch descends to the foot dorsum and spreads to the 3rd, 4th and 5th toes. 
    • The other branch connects with the Liver Primary Channel interiorly and exteriorly.
