Microglia are the cells in the CNS that can do this in normal, healthy tissue, and they are therefore also referred to as CNS-resident macrophages. The ependymal cell is a glial cell that filters blood to make cerebrospinal fluid (CSF), the fluid that circulates through the CNS. Because of the privileged blood supply inherent in the BBB, the extracellular space in nervous tissue does not easily exchange components with the blood.
Best Answer: The answer is C. Ependymal cells are neuroglia (supporting cells) that are ciliated, produce Cerebrospinal Fluid, and move them around the ventricles with the use of their cilia. * Schwann Cells are found in the Peripheral Nervous System, not in Central Nervous System. * Oligodendrocytes are found around axons, and do not produce CSF.
