Biology Question on neural control and coordination
Myelin sheath is produced by
A
Astrocytes and Schwann cells
B
Oligodendrocytes and Osteoclasts
C
Osteoclasts and Astrocytes
D
Schwann cells and Oligodendrocytes
Answer
Schwann cells and Oligodendrocytes
Explanation
Solution
Myelin sheath is an extended and modified plasma membrane that is wrapped around the nerve axon in a spiral mode. Myelin membranes originate from and are a part of the Schwann cells in the peripheral nervous system(PNS) and the oligodendroglial cells in central nervous system(CNS).
Osteoclasts are a large multinucleate bone cell that absorbs bone tissue during growth and healing. Astrocytes are star-shaped glial cells of the central nervous system.
Thus, the correct answer is D Schwann cells and Oligodendrocytes.
