According to most practitioners, there are 14 meridians – also known as energy pathways – that proceed through the human body. Along any of these meridians, there are several different points that can be manipulated with a needle to promote better energy flow. Just one of these is known as the lung meridian, for example. Strangely, the lung meridian, which is connected to breathing and cardiovascular health, has no points that are anywhere close to the upper chest. Instead, the points of the lung meridian run along the thumb, the wrist, the forearm, the elbow, the upper arm, the shoulder and the collarbone. In all, there are 11 such points that constitute the lung meridian. By comparison, the stomach meridian has 45 points. These run from the second toe, up the leg, over the tummy and chest towards the neck, chin and cheek, with the highest point located at the top of the forehead, to one side. In short, they're located all over the body.
