(B) In the $C.N.S.$ (Central Nervous System),the myelin sheath is formed by specialized glial cells known as $Oligodendrocytes$. Each $Oligodendrocyte$ can extend its cytoplasmic processes to wrap around multiple axons,thereby creating the myelin sheath. In contrast,in the $P.N.S.$ (Peripheral Nervous System),the myelin sheath is formed by $Schwann$ cells.
