  • CSF is produced at the choroid plexus, a network of permeable capillaries that extends into each of the four ventricles
Term
CSF location
Definition
  • CSF circulates throught the different ventricles, and fills the central canal of the spinal cord
Term
CSF flow
Definition
  1. Enters the subarachnoid space through openings in the roof of the fourth ventricle
