Fascia and its Effect on the Circulatory System and Nervous System

How fascia supports and sheaths the muscles
 Fascia can be compared to the body's own version of "Saran Wrap." It covers most of the body in large, continuously connected sheets. Injury, postural patterns and chemical imbalances can cause these sheets to distort and bind to themselves and nearby tissues. Since all major blood vessels and nerves follow these fascial sheathes through the body, properly aligned and released fascia is vital to good health and the proper operation of the circulatory and nervous systems (http://www.holisticonline.com/massage/mas_dysfunctions.htm).  Massage serves to align and increase flexibility of fascia which in turn leads to better posture, circulation, and transportation of nutrients to muscles, to name a few of the many benefits.
Fascia acts much like the white part of an orange or grapefruit, it holds the muscle fibers in "packages"
