Which Cells Produce Myelin in the Brain and Spinal Cord

Question

Which cells produce myelin in the brain and spinal cord?
A)Schwann cells
B)Astrocytes
C)Microglia
D)Oligodendrocytes

Accepted Answer

Oligodendrocytes are cells in the central nervous system (brain and spinal cord) that produce myelin, which is necessary for the efficient conduction of nerve impulses. Schwann cells, on the other hand, are cells in the peripheral nervous system that produce myelin. Astrocytes and microglia have different roles in the nervous system, such as providing support and protection to nerve cells and immune defense, respectively.
