Schwann Cells Differ from Oligodendrocytes in Which of the Following

Question

Schwann cells differ from oligodendrocytes in which of the following ways?
A) Schwann cells form myelin; oligodendrocytes do not.
B) Oligodendrocytes are only found in the PNS; Schwann cells are only found in the CNS.
C) Schwann cells form sheaths around several axons, while oligodendrocytes form sheaths around only one axon.
D) Schwann cells form a myelin sheath around a portion of only one axon, while oligodendrocytes can surround portions of several axons.
E) None of the choices are correct.

Accepted Answer

Schwann cells are found in the peripheral nervous system (PNS) and myelinate a single axon segment, while oligodendrocytes are found in the central nervous system (CNS) and can myelinate multiple axon segments.
