Which glial cell forms myelin in the central nervous system and can myelinate multiple axons?

Explanation:
Oligodendrocytes form myelin in the central nervous system, and one oligodendrocyte can extend multiple processes to wrap segments of several different axons. This allows a single cell to myelinate multiple fibers, speeding conduction via saltatory conduction. In contrast, Schwann cells in the peripheral nervous system myelinate a single axon segment each. Astrocytes support neuronal function and the blood–brain barrier, and microglia are immune-like cells; neither forms CNS myelin.
