Oligodendrocytes are small, rounded cells with one or a few processes, or extensions.
Central to these three paradigms are two cell types: endothelium and astrocytes. The endothelium produces several vasoactive factors that are germane to the regulation of cerebral blood flow: nitric oxide, endothelium-dependent hyperpolarization factor, the eicosanoids, and the endothelins.entral to these three paradigms are two cell types: endothelium and astrocytes.
