Neuroglia in the teleost (Channa striatus) central nervous system.

Neuroglia in the teleost (Channa striatus) central nervous system are of two categories: (1) Ependymal gliocytes with long processes having vascular and/or superficial terminal thickenings beneath the pia and (2) Non-ependymal gliocytes which are either primitive (unipolar and bipolar) or of classical macroglial type (astrocytes and oligodendrocytes). Interfascicular oligodendrocytes have been found amidst non-myelinated nerve fibre bundles, suggesting that they have not reached the phylogenetic maturation towards myelinogenic activity.
