According to the traditional Chinese description urinary bladder meridian is a yang channel associated with the element water and possesses interior and exterior relationship with the kidney meridian.
Total number of points: 67.
Starting point: Medial canthus of the eye.
Terminal point: Lateral side of the tip of the little toe.
Pathway: This is the longest channel. It starts from the medial canthus of the eye, runs over the forehead and head close to the midline. At vertex it connects with the governing vessels channel. At this level a small branch splits off and goes to the ear (this branch has no point) while the main branch goes to the occiput and at the nape of the neck, 0.5 t-sun above the natural hairline [UB-10 (Tianzhu)] it divides into the medial and lateral branches. These two branches descend down up to the back of the popliteal fossa where they unite in the center to form a single branch again. The single main branch runs down on the back of the leg and lateral border of the foot and ends at the lateral aspect of the tip of the little toe.
Medial branch: This branch runs on the back of the trunk 1.5 t-sun lateral to the midline. It descends down up to the fourth sacral foramen, makes a Z-turn to reach back to the first dorsal sacral foramen and then again descends down over the buttock, hip joint, back of thigh to reach the popliteal fossa where it meets the lateral branch. At the level of the lower border of the spinous process of the second lumbar vertebra [UB-23 (Shenshu)] an inner branch goes to the kidney and urinary bladder.
Lateral branch: This branch runs parallel to the medial branch 3 t-sun lateral to the midline on the back of the trunk. It courses over the buttock and back of the thigh and joins the medial branch on the back of the popliteal fossa at the level of UB-40 (Weizhong)
