interfascicular oligodendrocyte
Quick Summary
An interfascicular oligodendrocyte is a type of neuroglia found in the central nervous system. Its primary function is to produce myelin, which acts as an insulating sheath around the axons of nerve fibers. These cells are specifically located in rows between the nerve fibers within the white matter of the central nervous system. They are distinguished from other neuroglial cells, like astrocytes, by their denser cytoplasm and nucleus, and the presence of numerous microtubules in their processes. The myelin sheath formed by oligodendrocytes is crucial for efficient nerve impulse transmission, enabling signals to jump between gaps called nodes of Ranvier, a process known as saltatory conduction.123

nervous systemTypes of neurogliaInterfascicular oligodendrocytes are aligned in rows between the nerve fibres of the white matter of the central nervous system. In gray matter, perineuronal oligodendrocytes are located in close proximity to the somata of neurons. In the peripheral nervous system, neuroglia that are equivalent to oligodendrocytes…

oligodendrocyteOligodendrocytes are subdivided into interfascicular and perineuronal types and have few cytoplasmic fibrils but a well-developed Golgi apparatus. They can be distinguished from the type of neuroglia known as an astrocyte by the greater density of both the cytoplasm and the nucleus, the absence of fibrils and of glycogen…
