Full Definition
Cerebrospinal fluid (CSF) is a clear, colorless liquid that circulates around the brain and spinal cord within the subarachnoid space and ventricular system. It serves multiple functions including mechanical protection, removal of waste products, and transport of nutrients and hormones. CSF analysis through lumbar puncture is a crucial diagnostic tool in neurology for detecting infections, bleeding, inflammatory conditions, and malignancies affecting the central nervous system.
