<P> Lining the CSF - filled ventricles , the ependymal cells play an important role in the production and regulation of CSF . Their apical surfaces are covered in a layer of cilia , which circulate CSF around the CNS . Their apical surfaces are also covered with microvilli , which absorb CSF . Within the ventricles of the brain , a population of modified ependymal cells and capillaries together known as the tela choroidea form a structure called the choroid plexus , which produces the CSF . </P>
