Fascia is important tissue that surrounds the muscles, blood vessels and nerves in your body. This great article we found written by Dr. Kevin McIntyre of Burlington Sports Therapy explains why this tissue is so important to the human anatomy. Here's an excerpt:

Fascia.  What is it?  Many of you have likely heard this term used more and more over recent years.  This is perhaps due to the surge of new research on the topic and therefore the renewed interest within the manual medicine community.  Fascia can be defined as a sheet or band of fibrous connective tissue enveloping muscles, organs and other soft tissue structures of the body.  Fascia is divided into three separate layers that work closely with one another.  The most superficial layer (fascia superficialis) lies directly beneath the skin.  The middle layer (fascia profundus) has connections with fascia superficialis and directly overlies the muscles.  The deepest layer (deepest fascia or dural tube) directly surrounds and protects the central nervous system.
