The Kidney Meridian of foot - Shaoyin

The Kidney Meridian of Foot - Shaoyin starts from the inferior aspect of the small toe ( 1 ) and runs obliquely towards the sole ( Yongquan, K1 ) . Emerging from the lower aspect of the tuberosity of the navicular bone ( 2 ) and running behind the medial malleolus ( 3 ) , it enters the heel ( 4 ) . Then it amends along the medial side of the leg ( 5 ) to the medial side of the popliteal fossa ( 6 ) and goes further upward along the postero - medial aspect of the thigh ( 7 ) towards the vertebral column ( Changqiang, Du 1 ) , where it enters the kidney, its pertaining organ ( 8 ) , and connects with the bladder ( 9 ) . The straight portion of the meridian reemerges from the kidney ( 10 ) . Ascending and passing through the liver and diaphragm ( 11 ) , it enters the lung ( 12 ) , runs along the throat ( 13 ) and terminates at the root of the tongue ( 14 ) .

A branch springs from the lung, joins the heart and runs into the chest to link with the Pericardium Meridian of Hand - Jueyin ( 15 ) .

It enters its pertaining organ, the pericardium ( 1 ) . Then, it descends through the diaphragm ( 2 ) to the abdomen connecting successively with the upper, middle and lower jiao ( i.e., sanjiao ) ( 3 ) .

A branch arising from the chest runs inside the chest ( 4 ) , emerges from the costal region at a point 3 cun below the anterior axillary fold ( Tianchi P1 ) ( 5 ) and ascends to the axilla ( 6 ) . Following the medial aspect of the upper arm, it runs downward.
