system is a recently discovered physiological system. It is a semi-closed hydraulic system contained within a tough waterproof membrane (the Dura Mater) which envelopes the brain and the spinal cord. An important function of this system is the production, circulation and reabsorption of Cerebrospinal Fluid (CSF). CSF is produced within the
craniosacral system and maintains the physiological environment in which your brain and nervous system develop, live and function.
Normally, the production and reabsorption of CSF within the Dura Mater produces a continuous rise and fall
of fluid pressure within the craniosacral
system. The semi-closed hydraulic system expands and contracts to some extent with this rhythmical pressure fluctuation. This volumetric accommodation prevents pressure from building up too much within the
system. If for some reason your body is unable to to accommodate these pressure changes, the subsequent buildup of pressure can contribute to dysfunction and ill health, especially in the Central Nervous System which is enclosed within the boundaries of the
Investigation in this field was begun in the second decade of the twentieth century by William G.
Sutherland, D.O. Early exploration of cranial manipulation was performed primarily by osteopaths and chiropractors who formed societies to investigate and teach cranial methods. These pioneers were at
odds with the larger scientific community, and often with their own peers, over one central aspect of the cranial system: movement of the cranial bones.
Conventional anatomical wisdom taught that cranial bones were moveable only in young infants, and were solidly fused in adulthood. The controversy raged until quite recently.
In the early 1970's, the College of Osteopathic Medicine at Michigan State University sought to resolve this
controversy. By studying fresh cranial bone specimens, rather than the chemically preserved specimens which were studied by previous researchers, the Michigan State University team demonstrated the potential
for cranial bone movement. Optical and electron microscopy showed the existence of blood vessels, nerve fibers, collagen, and elastic fibers within the cranial sutures, but little evidence of sutural
ossification was found, which would prevent movement of the cranial bones in relation to each other.
With the existence of cranial bone motion established, elucidating the mechanisms behind this motion became
the task of the Michigan State University team. The results, influenced the therapeutic application of cranial techniques. These techniques for evaluating and treating the dural membranes were developed
largely by Dr. John E. Upledger, a member of the Michigan State University team. It is the central role of the dural membranes in the evaluation and treatment of the craniosacral
system that differentiates Craniosacral Therapy, as taught by the Upledger Institute, from other cranial techniques.
