Question

Myelinogenesis (Myelin formation) process occur in C.N.S. (central nervous system)

• A. By Schwann cells
• B. By oligodendrocytes
• C. By Axolemma
• D. By neurolemma

Answer 1

Answer: (B)

By oligodendrocytes

The plasma membrane surrounding the nerve axons is commonly referred to as the myelin sheath. It is found wrapped around the axons in a spiral fashion. It is synthesized by different cells in both PNS and the CNS. In the CNS, the oligodendrocytes synthesize it, while the Schwann cells synthesize it in the PNS.

So, the correct answer is 'By oligodendrocytes'.
