The bladder is called the 'Minister of the Reservoir' and is responsible for storing and excreting the urinary waste fluids passed down from the kidneys. As an organ the bladder has only this function, but as an energy system the bladder is intimately related to the functions and balance of the autonomous nervous system. That's because the bladder energy meridian runs along the back of the body from head to heal, with two parallel branches flowing along each side of the spinal column. These four branches of the bladder meridian exert a direct influence on the sympathetic and parasympathetic trunks of the autonomous nervous system, whose condition of modern life, over activates the sympathetic system, causing tension and pain along the spine and its periphery.
Passage with points
The meridian starts from the inner canthus (UB 1) ascends to the forehead joins the Du meridian at the vertex (Du 20) from there enters and communicates with the brain then emerges and descends along the posterior aspect of the neck at UB 10 bifurcates into two lines. The branch from the posterior neck runs downward and parallel to the vertebral column reaches the lumbar region continues to descend through the gluteal region and posterior thigh ends in the popliteal fossa. The branch from the posterior neck runs downward along the medial border of the scapula passes through the gluteal region goes downward along the lateral aspect of the thigh meets the preceding branch in the popliteal fossa from there descends to the leg and further to the posterior aspect of the lateral malleolus runs along the tuberosity of the 5th metatarsal bone reaches the lateral side of the tip of the little toe (UB 67), where it links with the kidney meridian.

The branch arises from the vertex runs to the temporal region of the head. The branch from the lumbar region enters the body cavity via the paravertebral muscle connects with the kidney enters its pertaining organ the urinary bladder.
