Before I start the modern thoughts on cellular level mechanics, another quote/incite from Dr. Still:
Philosophy of Osteopathy, Andrew Taylor Still, originally published 1899, chapter 10, pg. 73.
“The fascia gives one of, if not the greatest problems to solve as to the part it takes in life and death. It belts each muscle, vein, nerve and all organs of the body. It is almost a network of nerves, cells and tubes, running to and from it; it is crossed and filled with, no doubt, millions of nerve centers and fibers to carry on the work of secreting and excreting fluid vital and destructive. By its action we live, and by its failure we shrink, or swell, and die. Each muscle plays its part in active life. Each fiber of all muscles owes its pliability to that yielding septum-washer, that gives all muscles help to glide over and around all adjacent muscles and ligaments, without friction or jar. It not only lubricates the fibers but gives nourishment to all parts of the body. Its nerves are so abundant that no atom of flesh fails to get nerve and fluid supply there from.”
“This life is surely too short to solve the uses of the fascia in animal forms. It penetrates even its own finest fibers to supply and assist its gliding elasticity. Just a thought of the completeness and universality in all parts, even though you turn the vision of your mind to follow the infinitely fine nerves. There you see the fascia, and in your wonder and surprise, you exclaim, ‘Omnipresent in man and all other living beings of the land and sea.’ Other great questions come to haunt the mind with joy and admiration, and we can see all the beauties of life and exhibition by that great power with which the fascia is endowed. The soul of man with all the streams of pure living water seems to dwell in the fascia of his body.”
