4.2.1 The Large Intestine Primary

Channel (shou yang ming jing)

➡continues to ➞Du-14(dazhui) inferior to the spinous process

of the 7th cervical vertebra, where it meets with the other five

Yang primary channels

➡crosses the neck and enters the supraclavicular fossa at

➞ST-12(quepen).

Here the internalpathway branches off and connects with the

Lung (fei), its paired zang-Organ, penetrates the diaphragm and

enters the Large Intestine (dachang), its pertaining fu-Organ.

From the Large Intestine (according to some authors: the Large

Intestine primary channel) an internalbranch runs in an inferior

direction to ➞ST-37(shangjuxu) on the lateral aspect of the

lower leg, the lower he-sea point of the Large Intestine.

Pathway

The externalpart of the Large Intestine primary channel begins

on the index finger at ➞L.I.-1(shangyang, at the radial aspect

of the corner of the nail). This point is reached by a branch

which separates from the Lung primary channel at ➞LU-7

(lieque; hand Yin–Yang connection of the first great circuit).

The Large Intestine primary channel runs between the first and

second metacarpal bones,

➡then runs proximally along the radial aspect of the forearm

towards the lateral aspect of the elbow

➡travels in a proximal direction along the lateral aspect of the

upper arm towards the shoulder

➡crosses the Small Intestine primary channel at ➞S.I.-12

(bingfeng) in the centre of the suprascapular fossa
