Unike ligaments, aponeuroses, and tendons, fasciae are dense irregular connective tissues, containing closely packed bundles of collagen fibers oriented in a wavy pattern parallel to the direction of pull. Fasciae are consequently flexible structures able to resist great unidirectional tension forces until the wavy pattern of fibers has been straightened out by the pulling force. These collagen fibers are produced by the fibroblasts located within the fascia.
Fasciae are similar to ligaments and tendons as they are all made of collagen except that ligaments join one bone to another bone, tendons join muscle to bone and fasciae surround muscles or other structures.
Myofascia is defined as a layer of loose but strong connective tissue often containing fat covering and investing all muscles; an aponeurosis. The intrinsic connection between muscles and muscle fibers with connective tissue, fascia.
