Acupuncture points (acupoints) are located on energy pathways called meridians.
If you want to conceptualize these pathways, they are similar to our circulatory or nervous system. They are constantly flowing throughout the body.
Each meridian is connected to a different organ in the body. Each acupoint is located on these different meridians and is linked to help the proper functioning of that organ.
Modern CT scans and x-rays have shown that there is mirco-vessel clusters and increased microvascular structures at these points in the body compared to the areas where there isn’t an acupuncture point.
