For the new readers, I wrote about the direct connection of the craniosacral system and the fascial web in 2009. I believe that these two parts share equal importance. The full-body fascial web rules all, but the function of the craniosacral system, encased within, can determine the flow of cerebrospinal fluid into the web. Together, both parts function as one unit as defined below.
“The cerebrospinal fluid is the lifeblood of the craniosacral fascial system, an integration of the craniosacral and connective tissue components. This fluid starts its journey in the choroid plexus of the ventricles, gently fluctuates through the craniosacral system, and flows within the cranial and spinal nerve sheaths out into the billions of fine collagen tubules of the body’s fascial component. (Juhan, D. Job’s Body: A Handbook for Bodywork. Barrytown, New York 12507: Station Hill Press, 2003, page 73.) Researchers have confirmed this unified craniosacral fascial system by discovering cerebrospinal fluid in the collagen tubules with surprisingly no ordinary ground substance, blood, or lymph present. (Kessel, R., Kardon, R. Tissues and Organs: A Text-Atlas of Scanning Electron Microscopy. San Francisco: W. H. Freeman and Company, 1979, page 15.)
The lymphatic system returns this fluid to the venous system and onto the liver, heart, and lungs. Oxygenated blood then flows from the heart, through the aorta and carotid arteries, to the blood brain barrier of the choroid plexus. Blood exudates filter through the tight endothelial cell wall junctions and astrocytes of the capillaries to form the cerebrospinal fluid in the ventricles, thus completing the cycle.”
