Question

Myelin sheath is produced by:

• A. Astrocytes and Schwann Cells
• B. Oligodendrocytes and Osteoclasts
• C. Osteoclasts and Astrocytes
• D. Schwann Cells and Oligodendrocytes

Answer 1

The correct option is D Schwann Cells and Oligodendrocytes

The myelin sheath is a greatly extended and modified plasma membrane wrapped around the nerve axon in a spiral fashion. The myelin membranes originate from and are a part of the Schwann cells in the peripheral nervous system (PNS) and the oligodendroglial cells in the central nervous system (CNS).
Osteoclasts are a large multinucleate bone cell which absorbs bone tissue during growth and healing. Wher as astrocytes are a star-shaped glial cell of the central nervous system.
