Where does the urinary bladder meridian begin?

The urinary bladder meridian begins at the medial canthus of the eye. This point is significant as it marks the starting location for the bladder channel, which runs down from the head, traveling along the posterior aspect of the body and then down the legs. The pathway of the urinary bladder meridian is unique in that it is one of the longest meridians in the body, extending all the way to the feet.

Understanding this starting point is crucial because it helps in recognizing the trajectory of the meridian for both diagnostic and treatment purposes in acupuncture. Proper knowledge of where the meridian originates assists practitioners in identifying related acupoints and their therapeutic implications.

While the radial side of the wrist, the midpoint of the abdomen, and the lateral side of the foot are all important points in their respective meridians, they do not serve as the beginning of the urinary bladder meridian. Each meridian has its distinct starting point, which is essential for practitioners to accurately apply acupuncture techniques and understand the interconnections within the body's energy pathways.
