Question

Myelin of nerve fibres of CNS is produced and maintained by ________________.

• A. Microglia
• B. Schwann cells
• C. Astrocytes
• D. Oligodendrocytes

Answer 1

The correct option is D Oligodendrocytes

• Oligodendrocytes are highly specialized neural cells whose function is to myelinate central nervous system axons.
• Myelin sheaths are extraordinarily large extensions of the oligodendrocyte cell membrane and are highly complex structures.
• Oligodendrocytes main functions are to provide support and insulation to axons in the central nervous system of some vertebrates, equivalent to the function performed by Schwann cells in the peripheral nervous system. Hence, Myelin of nerve fibres of CNS is produced and maintained by Oligodendrocytes.

So, the correct answer is 'Oligodendrocytes'.
