cerebrospinal fluid (CSF)

The fluid flowing within the ventricular system that surrounds, cushions, and nourishes the brain and spinal cord. It is formed continuously by the choroid plexus in the ventricles, and is reabsorbed into the blood by the arachnoid villi at approximately the same rate at which it is produced; Examination of CSF for the presence of abnormal or excessive numbers of cells and protein content is an important source of information about the nervous system.
