|Fig. 2.01. The nuclei and bodies of nerve cell (N), oligodendroglia (O) and astrocyte (A) are present in this figure. Astrocyte nuclei are generally larger than oligodendroglia nuclei, however this astrocyte nucleus was sectioned closer to its edge here. Note the dark appearance of oligodendroglia. Scale = 5 µm.
