Cerebrospinal fluid (CSF) is produced by the
choroid plexuses of each of the four ventricles
(inset, lower left ).
2
CSF from the lateral ventricles flows to the third
ventricle.
3
CSF flows from the third ventricle through the
cerebral aqueduct to the fourth ventricle.
4
CSF exits the fourth ventricle through openings in
the wall of the fourth ventricle and enters the
subarachnoid space. Some CSF enters the central
canal of the spinal cord.

CSF flows through the subarachnoid space to the

where it enters the venous circulation (inset, upper right).
