What is the Craniosacral System?
The Craniosacral System a recently discovered system and is the system of the body that is responsible for the production, circulation, and reabsorption of Cerebrospinal fluid (CSF). It is a semi-closed hydraulic system , meaning that CSF is created and flows throughout the system and is reabsorbed in a constant, regulated rhythm of contraction and expansion. The Craniosacral System is made up of the cranial bones, sacrum, CSF, and meningeal membranes.
What is Cerebrospinal Fluid (CSF)?
Cerebrospinal fluid is fluid that is created in the brain. It brings nutrition to and removes waste from the central nervous system, and acts as a shock-absorbing cushion to the brain and spinal cord.
What are Meningeal Membranes?
The meninges are the Dura Mater, Arachnoid, and Pia Mater. They are three layers of membrane that surround the brain and spinal cord. CSF flows within these membranes.
What are the cranial bones?
There are 8 cranial, or skull bones. They are the frontal bone, 2 parietal bones, 2 temporal bones, the occipital bone, the sphenoid bone, and the ethmoid bone. They are joined together with sutures and can move slightly to accommodate the rhythm of the increase and decrease of CSF flow.
What is the sacrum?
The sacrum is a triangular-shaped bone that is formed from fused vertebrae and sits in the lower back in between the hip bones.
What is Craniosacral Rhythm?
Just like how the heartbeat can be felt throughout the body due to the beating of the heart in the circulatory system, the rhythmic motion of the Craniosacral flow can be felt throughout the body. This rhythm is very subtle but constant.
What is Fascia and how does it relate to the Craniosacral System?
Fascia is a sheet of connective tissue that covers all the muscles, organs, and other structures of the body and holds us together. All the fascia in the body is a single system, which means that everything in the body is interconnected because of it. Fascial diaphragms are the part of the fascia that run transversely (horizontally) across the body in specific areas. These areas tend to become restricted and cause muscular and somatic dysfunction. Though not a part of the Craniosacral System, releasing restrictions at these diaphragms can help release the Craniosacral System and bring balance to the body.
