cerebrospinal fluid (CSF)

« Back to Glossary Index

Cerebrospinal fluid (CSF) is a clear, colorless liquid that bathes the brain and spinal cord. Its primary purpose is to protect the brain and spinal cord, acting as a barrier and shock absorber. This fluid also circulates nutrients and chemicals that are filtered from the blood and removes waste products, antibodies, chemicals, and disease-causing substances away from the brain and spinal-cord tissue into the bloodstream.
