[Glial cells of the retina in Rana ridibunda Pall].
Four types of frog (Rana ridibunda Pall.) retinal glial cells have been described: radial gliocytes (Müller's fibers), oligodendrocytes, spider cells and microglial cells. Estimation of the glial cells has been made for the central, middle and peripheral retinal zones. Oligodendrocytes are predominantly satellites of large neurons in the ganglion layer. The frequency of their occurrence among other cells increases from the retinal center to the periphery. The spider cells are mainly distributed over the central retinal zone, but they are not found in the peripheral one. The microglial cells occur in the ganglion layer more rarely than other glial elements and predominantly in the middle and peripheral retinal zones. Besides, they are presented in the external and internal synaptic layers.
