All tissues in the body have internal and external biofilms, also known as tegument, which are composed of fibrous connective tissue and can be referred to as fascia. The biofilm inside and outside the muscle tissue is called myofascia. Myofascia is a general term for the fibrous connective tissue inside and outside muscle fibers, and is divided into three categories: 1) extramuscular fascia, which is located between muscles or muscle groups, and can be connected with peripheral vascular nerve membranes, periosteal membrane around bones, external tegument of organs, subcutaneous superficial fascia, etc., to coordinate muscle contraction, complete joint activities, form movements, maintain posture and volume of body cavity; 2) fascial structures around muscles, connecting different muscle bundles. 3. intramuscular fascia, which is connected to each other, and there are some regional structures where fibroblasts are concentrated – “coordination
The synapses of these cells can sense the displacement of muscle segments and shorten or extend them accordingly, adapting to the contraction of muscle fibers, which is the anatomical basis for the extension and contraction of the fascial system to form coordinated movements. The whole body can be considered as a macroscopic to microscopic fascial network system, and the same is true for myofascia. This is similar to the architectural indefinite tensegrity
model). Muscle tissue contains only motor nerves, not sensory nerves. Myofascia, on the other hand, has sensory nerve endings. Since maintaining good extension and contraction properties of the fascia is the basis for coordinating muscle contraction and diastole and maintaining the body’s motor function, if local injury or inflammation of the fascia or adhesion occurs, it will produce uncoordinated movement, stiffness, pain and pressure pain, etc., which is called myofascial pain, also known as myofasciitis, myofibrositis, muscle strain, etc.
