Cerebrospinal Fluid (Csf)

Cerebrospinal Fluid (Csf) is an important fluid that protects the brain and spinal cord. It is transparent and fills the subarachnoid space, the ventricles of the brain and the central canal of the spinal cord. The brain floats in this fluid, which allows it to reduce its weight from 1400 g to less than 100 g. This protects the brain from contact with the skull during vigorous head movements.

Cerebrospinal fluid is produced by the epithelium covering the choroid plexuses of the ventricles of the brain. It passes through these plexuses and reaches the subarachnoid space, where it protects the brain from shock and other damage. Ultimately, CSF is absorbed into the venous blood through the arachnoid granulations, as well as into the blood and lymphatic capillaries at the exit of the cranial and spinal nerve roots.

The composition of cerebrospinal fluid includes water, glucose, various salts, enzymes and a certain number of white blood cells. It is important to note that CSF does not contain red blood cells.

Cerebrospinal fluid performs several important functions. It protects the brain from shock and other damage, and also ensures a constant supply of nutrients and oxygen to the brain. Additionally, it helps remove waste and metabolites from the brain.

Changes in the composition or amount of cerebrospinal fluid may indicate the presence of disease. For example, an increase in proteins in the CSF may indicate the presence of an infection or tumor. An increase in white blood cell count may also indicate infection or inflammation.

Overall, cerebrospinal fluid is an important part of the protection of the brain and spinal cord. It performs several important functions and changes in its composition may indicate the presence of diseases.



Cerebrospinal Fluid (CSF) is a clear fluid that fills the subarachnoid space (the space between the arachnoid membrane and the pia mater) and the ventricles of the brain. It plays an important role in protecting the brain and spinal cord from injury and damage.

Cerebrospinal fluid is formed by the secretion of the epithelium covering the choroid plexuses in the ventricles of the brain. Passing through the choroid plexuses, the fluid reaches the subarachnoid space and is absorbed into the blood through arachnoid granulations.

The cerebrospinal fluid contains water, glucose, some salts, as well as enzymes and a small number of white blood cells. However, unlike blood, red blood cells do not enter the cerebrospinal fluid.

Cerebrospinal fluid performs several important functions. Firstly, it protects the brain and spinal cord from contact with the bones of the skull and spine during sudden movements of the head, which helps reduce the weight of the brain from 1.4 kg to 100 grams. Secondly, cerebrospinal fluid is involved in the exchange of substances between blood and brain tissue, ensuring the supply of nutrients and the removal of metabolic products. In addition, cerebrospinal fluid acts as a shock absorber, preventing concussions from impacts and falls.

The importance of cerebrospinal fluid for human health is difficult to overestimate. Violation of its formation or composition can lead to various diseases, such as meningitis, encephalitis, hydrocephalus and others. Therefore, it is important to monitor the condition of your cerebrospinal fluid and, if necessary, undergo regular examinations with a doctor.



Cerebrospinal Fluid Csf (English: Cerebrospinal Fluid) is a clear liquid fluid that protects the brain and spinal cord. It contains the central cavity and vesicular spaces of the medulla and the central canal of the spine. The brains float in it, which reduces its mass from about 1.4 kg to 1 kg.

It is formed from the epithelium that forms the basis of the choroid plexuses located in the ventricles of the brain, allowing it to ultimately reach the subpacutinal region. It is then absorbed back into the systemic circulation via arachidial granules and blood and lymphatic capillaries near the root of the brain and spinal nerves.

The composition of the cerebrospinal fluid includes water, glucose, various salts and enzymes. Also a small amount of white
