4.7.1 The Bladder Primary Channel
(zu tai yang jing)
Pathway
The externalpathway of the Bladder primary channel begins at
the inner canthus of the eye at ➞BL-1(jingming). This point is
reached by a branch that separates from the Small Intestine pri-
mary channel at ➞S.I.-18(quanliao) (hand–foot pairing of the
second great circuit, Yang axes: taiyang).
The externalpathway ascends the forehead, there intersects with
➞Du-24(shenting) and ➞G.B.-15(toulinqi), continues to the
vertex and there connects with the du maiat ➞Du-20(baihui).
At ➞Du-20 two branchesseparate from the primary channel:
➡one branchtravels to the temporal region and intersects the
Gall Bladder primary channel at G.B.-8(shuaigu), G.B.-7
(qubin), G.B.-9 (tianchong), G.B.-10 (fubai), G.B.-11
(touqiaoyin) and G.B.-12(wangu)
➡the other branchpenetrates deeper into the brain and re-
emerges at ➞Du-17(naohu) or, according to some authors,
at BL-8(luoque).
From ➞Du-20, the external pathwayruns to BL-8(luoque)
and BL-9(yuzhen), passes ➞Du-17(naohu) and continues to
BL-10(tianzhu) in the occipital region. Here, the external
pathwayof the channel separates into two branches:
➡the medialbranch runs to ➞Du-14(dazhui) below the
spinal process of C7 where it meets the other Yang primary
channels, then continues to ➞Du-13(taodao). From T1 it
runs parallel to the posterior midline, 1.5 cun lateral to it.
