Question

Myelin sheath is produced by:

• A. Schwann cells and oligodendrocytes
• B. astrocytes and Schwann cells
• C. oligodendrocytes and osteoclasts
• D. osteoclasts and astrocytes

Answer 1

The correct option is A Schwann cells and oligodendrocytes

The myelin sheath is a white insulating sheath that is wrapped around the axon in a spiral manner.

In the peripheral nervous system (PNS), Schwann cells produce myelin sheath and in the central nervous system (CNS), oligodendrocytes produce the same.

Astrocytes are a type of glial cells found in CNS. They regulate the blood-brain barrier.

Osteoclasts are responsible for the process of bone resorption (breaking down the tissues in bone and releasing minerals). They play a pivotal role in skeletal development.
