Final answer:
Schwann cells are functionally similar to oligodendrocytes. Both Schwann cells and oligodendrocytes produce the myelin sheath that insulates axons and play a crucial role in nerve impulse conduction.
Step-by-step explanation:
Schwann cells are functionally similar to oligodendrocytes in the central nervous system (CNS).
Oligodendrocytes, like Schwann cells, are responsible for producing the myelin sheath that insulates axons. However, Schwann cells specifically insulate peripheral axons in the peripheral nervous system (PNS), while oligodendrocytes produce myelin in the CNS.
Both Schwann cells and oligodendrocytes play a crucial role in nerve impulse conduction by providing insulation and support to the axons.
