1 CSF is produced by the
choroid plexus of each ventricle.
2 CSF flows through the ventricles
and into the subarachnoid space via
the median and lateral apertures.
Some CSF flows through the central
canal of the spinal cord.
3 CSF flows through the
subarachnoid space.
4 CSF is absorbed into the dural
venous sinuses via the arachnoid
villi.
