Myofascial is known by a few names: connective tissue, extracellular matrix, ground substance and interstitial spaces.  A basic understanding of fascia explains that this is a tissue system that connects everything in the human body.  There are no empty spaces and this  fibers  network is the tissue that fills the areas between anatomical structures.  Fascia is a network of collagen fibers with no orderly logic to its arrangement but works to ensure efficient movement of structure.

Myofascial release relaxes muscles and improves blood and lymphatic circulation.
