Cerebrospinal Fluid

Liquor is a liquid found in the CNS. It circulates in a system of communicating cavities, which we call CSF space in its entirety. It is a water-clear protein-poor liquid which contains only few cells. Most of these cells are Leukocytes - up to 3 leucocytes per ml cerebrospinal fluid.

About 500-700 ml of cerebrospinal fluid are formed daily in all four brain ventricle ventricles. Since there is only about 150 ml of fluid in the entire cerebrospinal fluid system, the cerebrospinal fluid must be reabsorbed into the blood pathway. Even relatively small fluctuations in the target volume can lead to negative or positive pressure in the brain area, which can have dramatic consequences.

The cerebrospinal fluid serves primarily for the metabolism of the nerve cells of the CNS and as protection for the brain by forming a kind of water cushion around the brain and thus protecting it against external mechanical influences.
