Path of the Bladder meridian
The Bladder meridian, Taiyang of foot, will begin at the inner canthus of the eye at the point Jingming.
It goes up the forehead passing through the inner end of the eyebrow.
It goes back along the skull and when it reaches the apex (the top of the skull), it will pass through Baihui (point of Renmai meridian).
It continues to run along the skull to its base posteriorly, at the point Tianzhu.
It will go down along the nape of the neck and at the height of C7-D1 it sends a branch which passes through Dazhui before going down.
It will then go through the entire spine (dorsal and lumbar) and it is 1.5 cun outside the spine.
At the level of the L2 vertebra, at the point Shenshu, it sends an internal branch which will couple to the Kidney and bind to the Bladder.
It crosses the sacrum, descends on the posterior side of the thighs, to the middle of the popliteal fossa, at the point Weizhong.
A second branch leaves the main path at the level of the neck, goes down all along the spine, 3 cun from the spine.
It crosses the buttock, goes down the posterior side of the thigh to join the first at the point Weizhong.
From Weizhong point, we only have one branch which goes down, crosses the middle of the posterior then postero-external side of the leg, then passes behind then below the external malleolus, runs along the external edge of the foot and ends at the external nail angle of 5th toe in point Zhiyin.
It's to the point Zhiyin that the direct connection will be made with the Kidney meridian at the point Yongquan.
