The Fascia Explained
Movement, support, stability, blood flow, fluid dynamics, nerve transmission, and more — it all happens in the connective tissue called fascia.
In the illustration by Frank H. Netter, notice how each group of muscles, and bundle of nerves and vessels surrounding the bone is separated and surrounded by a translucent, fibrous connective tissue. This tissue is the fascia. It serves as both a boundary and a point of connection between every structure within the body. It is similar in its material composition (which is mostly collagen) to tendons and ligaments, but its function is different. Whereas ligaments connect bone to bone and tendons attach bone to muscle, the layers of fasciae encase organs, muscles, bones, nerves, and blood vessels.
The Function of the Fascia
When the body is in motion, the fascia provides structure, support, separation and lubrication for the coordinated sliding and movement of its internal components. The fascia itself is living tissue containing nerve endings, and therefore it also provides a network of communication between the central nervous system and the organs and tissues of the entire body. In fact, scientists now believe that the other internal structures — bones, organs, blood, nerves, vessels, and more — are specialized tissues born from fascia. The similarities between these different types of tissues, rooted in a shared origin, helps explain the interconnectivity of the body.
Keeping the Fascia Healthy
The health of the fascia can be compromised by two main causes: inflammation and immobility. Inflammation can be caused by injury, overuse, misuse, and other factors. Immobility occurs from the lack of use or movement. Both inflammation and immobility eventually cause the microfibers of the fascia to dehydrate and thicken. The lack of fluid and movement in between adjacent layers of connective tissues binds them together, which reduces range of motion, impedes blood flow, and impinges nerve fibers.
If not addressed, the thickened microfibers of damaged fascia become comparable to an internal cast for the body. Even after a traumatized area has healed, these adhesions do not go away; they accumulate over time, causing increased stiffness, pain, and even a burning sensation as we age.
Therapies like acupuncture treatment, electro-acupuncture, trigger point dry needling, cupping, guasha, and other manual techniques each work in their own way to address aspects of fascia health. All of the therapies provided at South Jersey Sports Acupuncture work directly with the fascia. With skillful application, they can be used to combat and release the stiffness and tension caused by the accumulation of fascial adhesions. Many times, immediate relief can be felt as health is restored to the fascial network.
