The Cerebro-Spinal Fluid

I have decided to write about the cerebrospinal fluid (CSF) partly as we find ourselves talking about it a lot during our sessions and partly as it is one of the most important elements of the body. Learning about the anatomy and the function of its elements will help understanding why the CSF is so essential for a good health and therefore its importance in our treatment.

Anatomy and physiology

The cerebro-spinal fluid is a liquid found around the central nervous system and is produced continually within the choroid plexus an area within the ventricles of the brain. It is then transported within semi-closed areas including the subarachnoid place and the ventricular system.
These areas suround and penetrate the brain and spinal cord.

It is reabsorbed into the veins via the arachnoids granulations. The movement created by the creation and the resorption of the fluid is called primary respiration.
Its molecular composition is close to water but it has its own particular role within the body.

What does it do?

This liquid is there to protect the brain and the spinal cord. It absorbs shocks and movements by distributing the force of the impacts.

If there is a change of pressure within the skull this fluid can be produced in different quantities to regulate the pressure and protect the brain.

It is also a very important part of the immune system. It has the task of cleaning by taking molecular waste away from the nervous system. It also carries a lot of protectives immunologic cells.

Its importance it our treatment

As you can see, this fluid is highly important in the wellbeing of the body and any change to it will affect the whole body. If the liquid can’t flow normally in an area the nervous system will be impacted. This could cause a reducing of the cushioning effect it, an accumulation of waste and a weakened immunity of this area.

It is imperative the fluid has harmonic movement around the brain and spinal cord to ensure it can complete its job. Any change within the bone structures or even the muscles surrounding the nervous system could create different tensions on the membranes around the CSF and imbalance/disturb its movements.

It is important in our sessions to keep that in mind and focus on the balance of this precious fluid, we can help rebalancing it with craniosacral techniques by focusing on the primary respiration movement. To do so, we work gently on the movement of the sacrum via muscles and fascia around it and on the movement of the skull via the synarthrodial joints which are in between the numerous skulls bones. Working directly on the fascia helps as they are directly connected to the joints in between the bones and also to the membrane around the nervous system (continuity of the tissues).

I hope that you will understand a bit more what we do next time you see us working!
