Appreciating the layered formation of the fascia is key to understanding how this tissue functions, what can go wrong, and how to fix it. The collagen fiber bundles in each layer lie parallel to each other, much like my fingers. But in the next layer those collagen fibers are oriented in a different direction. They are thought to govern movement according to the orientation of the fibers in each layer, and require separation (space) and lubrication (slide) between the layers.
