What Is a Cerebral Spinal Fluid Test?
Cerebrospinal fluid (Cerebrospinal fluid) is a fluid secreted by the choroid plexus (which is found above the round mouth) that occupies a part of the ventricle wall of vertebrates and fills the ventricle. The subarachnoid space extends from the median foramen and the lateral foramen of the brain to the spinal cord. In addition to participating in mechanical protection, it also becomes an exhaust pathway for metabolites of the central nervous system, and is finally absorbed by the venous system. It is a weakly alkaline and transparent water sample solution containing 1 to 6 lymphocytes in one milliliter.

- The brain itself is very delicate, but there is a strong round skull. The shape of the skull not only guarantees the smallest volume and maximum capacity, but also meets the purpose of protecting the brain from a mechanical point of view. The football team often shot the ball overhead and the brain was not injured. This is because there is a layer of fluid between the brain and the skull as a buffer, which is cerebrospinal fluid. In fact, the brain is floating in the cerebrospinal fluid. When the skull is impacted, external forces can be dispersed through the cerebrospinal fluid, so that the brain is not affected. When the head's movement direction and speed suddenly change, the brain will not be hit by the inertia The inner wall is separated by cerebrospinal fluid.
