Lower Yang Channels

Lower Yang Channels
 
The Stomach, Gall Bladder and Urinary BladderChannels are the Lower Yang Channels that begin around the eye and end on thetoes. They are the longest channels of each cycle.
 
The ST Channel begins below the Pupil of the eye andruns Anterior along the Abdomen and the Thigh, and from the Patella takes alateral course to end on the Second Toe. (Though an Yang Channel ST channel runs Anterior up to thePatella).
 
The UB Channel begins near the Inner Canthus of theeye  and runs upward along the scalp anddescends on the Back, along the pathway of the Autonomic Nervous System  and runs on the back midline of the Gluteumand Thigh up to the Popleteal crease. Then the channel runs lateral to the leg and ends on the Fifth toe outernail base. (TheChannel bifurcates on the nape area and both the branches meet at the Popletealcrease).
 
The GB Channel begins on the outer Canthus of theeye and then traverses 20 points on the Cranial area in Zigzag curves.  Then the channel descends laterally on theShoulder and Flank areas and passes along the lateral side of the leg, to endon the Fourth toe nail base.
