The Cranium is the portion of the skull that houses the brain.  The cranium is not one solid bone.  The cranium consists of a single frontal bone (forehead), occipital (back of the head), sphenoid (butterfly shaped bone behind the eyes),  ethmoid (medial wall of the eye socket) and paired temporal bones (around the ears, back of the temple) and  parietal bones (above the temporal bones back to the coronal suture and the sagittal suture).   These bones articulate 6 – 12 times a minute.

The Sacrum is a triangular bone between the ilia bones (hip bones), the fifth lumbar vertebra and the coccyx (tail bone).  The sacrum is made up of five united vertebrae and is wedged between the innominate bones.   The articulation of these bones makes  up the sacroiliac joints (SI joints) .   It is the base of the vertebral column (spine) and along with the coccyx forms the posterior boundary of the true pelvis.

The cervical vertebrae, thoracic vertebrae, and lumbar vertebrae are segments of the spinal column.

The cranium, spinal column and sacrum make up the CranioSacral system.   CranioSacral therapy uses a very light pressure, only the weight of a nickel, and works with the membranes and fluid of the CranioSacral system allowing for the body to begin addressing from the inside out how to heal itself.

The client should wear loose fitting comfortable clothing.  The CranioSacral therapy is done with the client on top of the massage table and the client stays dressed.
