CIRCULATION OF CEREBROSPINAL FLUID •<br />
CSF circulates through the four brain ventricles (two lateral ventricles<br />
and a third and fourth ventricle) and in the subarachnoid<br />
space surrounding the brain and spinal cord. Most of the CSF is<br />
reabsorbed into the venous system through the arachnoid granulations<br />
and through the walls of the capillaries of the central nervous<br />
system and pia mater.<br />
