The cerebrospinal fluid (CSF) performs several vital functions within the central nervous system. According to the provided reference, here are four primary functions:
Functions of Cerebrospinal Fluid (CSF)
The CSF, which occupies the central spinal canal, the ventricular system, and the subarachnoid space, is crucial for the health and function of the brain and spinal cord.
| Function | Description |
|---|---|
| Support | CSF helps to support the brain, reducing its effective weight and preventing it from being crushed under its own mass. |
| Shock Absorber | CSF acts as a cushion, protecting the brain and spinal cord from trauma. |
| Homeostasis | CSF contributes to maintaining a stable chemical environment for the brain and spinal cord. |
| Nutrition & Immunity | CSF provides nutrients to the brain and spinal cord, and also carries immune cells and antibodies. |
In summary, the four key functions of the cerebrospinal fluid are: support, acting as a shock absorber, maintaining homeostasis, and providing nutrition and immune function.
