Cerebrospinal Fluid
Cerebrospinal Fluid
Cerebrospinal Fluid (pronounced: /ˌsɛrɪbroʊˈspaɪnəl ˈfluːɪd/), often abbreviated as CSF, is a clear, colorless body fluid found in the brain and spinal cord. It is produced by the specialized ependymal cells in the Choroid Plexus of the ventricles of the brain, and absorbed in the arachnoid granulations.
Etymology
The term "Cerebrospinal Fluid" is derived from the Latin cerebrum for "brain", spina for "spine", and fluidus for "fluid".
Function
The primary role of the CSF is to cushion the brain within the skull and serve as a shock absorber for the central nervous system. CSF also circulates nutrients and chemicals filtered from the blood and removes waste products from the brain.
Related Terms
- Hydrocephalus: A condition in which an accumulation of CSF occurs within the brain. This typically causes increased pressure inside the skull.
- Lumbar Puncture: A medical procedure where a needle is inserted into the lower part of the spine to test for conditions affecting the brain, spinal cord or other parts of the nervous system.
- Meningitis: An inflammation of the meninges, the membranes that cover the brain and spinal cord. It can occur due to infections, including those caused by bacteria, viruses, or fungi. CSF analysis is a crucial part of the diagnostic process for meningitis.
