Explanation:
Detailed explanation-1: -Myelin is made by oligodendrocytes in the central nervous system (CNS) and Schwann cells in the peripheral nervous system (PNS).
Detailed explanation-2: -Both myelinating and non-myelinating Schwann cells are covered by a basal lamina. The outside of the lamina is surrounded by a layer of connective tissue namely the endoneurium, which contains blood vessels, fibroblasts, and macrophages. Whereas, the inner surface of the lamina faces the Schwann cell plasma membrane.
