Glossary of Terms
cerebrospinal fluid [CSF]
Cerebrospinal fluid (CSF) is a clear, colorless fluid that surrounds your brain and spinal cord. Its main job is to protect your brain and spinal cord by acting as a barrier and shock absorber. CSF also removes waste products, antibodies (substances that help your body fight infections), chemicals, and disease-causing substances from your brain and spinal cord.
