WebbThe choroid plexus is a spongy, vascularized structure that produces CSF and is attached to the walls of ventricles. It contains capillaries of choroidal arteries that are covered by an ependymal epithelial layer. The ependymal cells express tight junctions, providing a barrier between the fenestrated blood vessels and the CSF ( Fig. 1C ).
