What is the FUNCTION of CSF?

What is the CHOROID PLEXUS?

What is the STRUCTURE of the Choroid Plexus?

1) Very simple structure

2) Capillary network surrounded by cuboidal epithelium

3) During CSF production:

  1. Blood filtered through fenestrated capillaries

  2. Components transported through cuboidal epithelium into ventricles
