What is the Craniosacral System?

The Craniosacral System is made up of four major parts, but affects the entire body, as it influences not only the nervous system, but others as well. The parts of the Craniosacral System are:

Cerebrospinal Fluid

A clear fluid produced in the brain, cerebrospinal fluid fills parts of the brain and the center column of the spinal cord. As cerebrospinal fluid circulates, it creates a rhythm that your bones also replicate. This rhythm is what a craniosacral therapist feels for when assessing the body to find restrictions in the system.

Lining of the Brain and Spinal cord

The lining of the brain and spinal cord are also referred to as the meninges, and is split up into three parts starting with the outermost layer. These are called the dura mater, the arachnoid mater, and the pia mater. Cerebrospinal fluid circulates in between the arachnoid mater and the pia mater. The primary purpose of these layers is to protect our central nervous system. It is possible for the meninges to become tight, just like a muscle, and a cranosacral therapist can help relieve that tension.

Spinal Cord

A tube that stretches from your brain to the low back, the spinal cord sits along the spine, controlling motor function and nerve signals throughout the body. As a key part of the nervous system, any time pain or other sensations are felt, the spinal cord is the one receiving the information.


The sacrum is a triangular bone that sits at the base of the spine, in between the two wings of the pelvis. It adds support to the spine and spinal nerves.

The entire system works together in harmony, and every part of the system is addressed during a session. For example if someone has come in after a bad fall on the sacrum, it could have an adverse affect on the head. My goal is to bring a balance back to the system and help remove restrictions in flow of the cerebrospinal fluid. If you feel this kind of work would benefit you I’d love to see you for an appointment!
