Final answer:
Schwann cells and oligodendrocytes are both glial cells that produce the myelin sheath in the nervous system. They differ in location and the number of axon segments they wrap around.
Step-by-step explanation:
Schwann cells and oligodendrocytes are both types of glial cells that produce the myelin sheath in the nervous system. However, they differ in terms of their location and the number of axon segments they wrap around.
Schwann cells are found in the peripheral nervous system (PNS) and wrap around a single axon segment, while oligodendrocytes are found in the central nervous system (CNS) and can wrap around multiple axon segments.
