FASCIA: THE TIES THAT BIND Imagine a collagen-rich, stretchy slipcover for every organ, nerve, bone, and muscle in our bodies, and you start to get a sense of how fundamental connective tissue—specifically fascia—is to the entire body. Suspending our organs inside our torso, connecting our head to our back to our feet, fascia protects, supports, and literally binds our body together. Fascia can be gossamer-thin and translucent, like a spider web, or thick and tough like rope. Ounce for ounce, fascia is stronger than steel. Other specialized types of connective tissue include bones, ligaments, tendons, cartilage, and fat (adipose) tissue. Even blood, strictly speaking, is considered connective tissue. But to me, the most exciting aspect of the latest research on connective tissue relates to fascia. Fascia is the stretchy tissue that forms an uninterrupted, three-dimensional web within our body. Our body has sheets, bags, and strings of fascia of varying thickness and size, some superficial and some deep. Fascia envelops both individual microscopic muscle filaments as well as whole muscle groups, such as the trapezius, pectorals, and quadriceps. For example, one of the largest fascia configurations in the body is known as the “trousers,” a massive sheet of fascia that crosses over the knees and ends near the waist, giving the appearance of short leggings. This fascia trouser is thicker around the knees and thinner as it continues up the legs and over the hips, thickening again near the waist. When the fascia trouser is healthy, supple, and resilient, it acts like a girdle, giving the body a firm shape. Fascia helps muscles transmit their force so we can convert that force into movement. The system of fascia is bound by tensile links (think of the structure of a geodesic dome, like the one at Epcot in Disney World), with space and fluid between the links that can help absorb external pressure and more evenly distribute force across the fascial structure. This allows our bodies to withstand tremendous force instead of absorbing it in one local area, which would lead to increased pain and injury. Fascia is also a second nervous system in and of itself, with almost 10 times the number of sensory nerve endings as muscle. Helene Langevin, director of the Osher Center for Integrative Medicine at Harvard Medical School, has done landmark studies on the function and importance of connective tissue and its impact on pain. One of the leading researchers in the field today, Langevin describes fascia as a “living matrix” whose health is essential to our well-being.
