oligodendrocytes
|
|
|
osteocytes
|
|
|
Myocytes
|
|
|
Schwann cells

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).
Detailed explanation-2: -The central function of oligodendrocytes is to generate myelin, which is an extended membrane from the cell that wraps tightly around axons.
Detailed explanation-3: -Glial Responses to Injury In 1921, Rio Hortega officially named these cells oligodendrocytes, which means ‘few tree cells. ‘ Like other glia, oligodendrocytes are found throughout the CNS gray and white matter, where individual oligodendrocytes can myelinate as many as 40–50 axons.
