Fascia is the key material within the body that gives all the organs, muscles, and connective tissue structure. It’s a latticework made of collagen and a lubrication substance that helps it glide  freely over bones and muscles and the skin. When someone gets “adhesions”, what is meant is that the fascia has become adhered or stuck to the structure surrounding it. Think of plastic wrap getting stuck to itself after you have torn it away from the dispenser and before you can get it secured on the bowl you want it to seal. It is much the same for fascia. Scar tissue is also made of a thickened fascia.
