Neuroglia. This image is a high magnification of the gray matter of an anterior horn illustrating the nuclei of neuroglia. Round nuclei belong to Oligodendrocytes (red arrows). These cells are closely associated with the cell processes of neurons. Oligodendrocytes located in the white matter are responsible for producing the myelin sheath around the neuronal processes. The black arrows are pointing to the nuclei of Astrocytes. These cells have many cytoplasmic processes and are connected to other cells and blood vessels. They basically help maintain the structural integrity of the CNS since there is no connective tissue. Astrocytes in the gray matter are referred to as Protoplasmic Astrocytes and those in the white matter are referred to as Fibrous Astrocytes.
