Cerebrospinal Fluid (CSF) is a clear, watery fluid that circulates through the ventricles of the brain, the central canal of the spinal cord, and the subarachnoid space.

CSF is primarily produced by the choroid plexus, which is a network of highly vascularized, specialized ependymal cells located within the ventricles of the brain (lateral, third, and fourth ventricles).
