Explanation:
Detailed explanation-1: -Schwann cells make myelin in the peripheral nervous system (PNS: nerves) and oligodendrocytes in the central nervous system (CNS: brain and spinal cord). In the PNS, one Schwann cell forms a single myelin sheath (Figure 1A).
Detailed explanation-2: -Oligodendrocytes are the glial cells where myelin is produced in the central nervous system, and Schwann cells are responsible for producing myelin in the peripheral nervous system.
Detailed explanation-3: -Schwann cells (SCs), named after German physiologist Theodor Schwann (1810–1882), are the main neuroglial cells of the peripheral nervous system (PNS).
