Title: The BCB Blood CSF Barrier and the Choroid Plexus the delicate knot from Latin: chorion delicate, ple


1
The BCB (Blood CSF Barrier)and the Choroid
Plexus(the delicate knot)from Latin chorion -
delicate, plexus knot
2
Its Location
  • The ependymal cells (also called choroid
    epithelial cells) that line
  • the ventricles of the brain fuse with the
    pia mater to form the
  • choroid plexuses.

Its Location
  • The ependymal cells (also called choroid
    epithelial cells) that line
  • the ventricles of the brain fuse with the
    pia mater to form the
  • choroid plexuses.

The lateral ventricles are illustrated in pink,
the third and the fourth ventricle is shown in
green. The choroid plexus is illustrated in red.

Its Structure
  • The ependymal cells (also called choroid
    epithelial cells) that line
  • the ventricles of the brain fuse with the
    pia mater to form the
  • choroid plexuses.
  •   The choroid plexuses are branched structures
    made up of
  • numerous villi, thus providing a large
    surface area for the
  • secretion of CSF.
  • The choroid plexus has a rich blood supply,
    for example, the rat
  • lateral and fourth ventricle plexuses
    receive 3- 4ml.min-1.g-1
  • which is almost 10 times greater than the
    flow to the cerebral
  • cortex.
