Surface fine structure of the ependymal lining of the rat fourth ventricle.
The floor of the rat brain fourth ventricle has been divided into five zones to study the surface ultrastructure of the ependymal cells. Regional variations in the form of dense ciliation, sparse ciliation, central tufts of cilia, solitary cilia, pores, clavate and filiform microvilli have been observed.
