ependymal cells

|
oligodendrocytes
|
|
|
Schwann cells
|
|
|
astrocytes
|
Explanation:
Detailed explanation-1: -They form as the result of reciprocal interactions between axons and Schwann cells. Extrinsic signals from the axon, and the extracellular matrix, drive Schwann cells to adopt a myelinating fate, whereas myelination reorganizes the axon for its role in conduction and is essential for its integrity.
Detailed explanation-2: -Myelin is made by oligodendrocytes in your brain and spinal cord (your central nervous system [CNS]) and by Schwann cells in your peripheral nervous system.
