In the CNS, axons are myelinated by
A) vesicles.
B) oligodendrocytes.
C) unipolar cells.
D) astrocytes.
E) Schwann cells.

Question

Quizplus · Accepted Answer

Oligodendrocytes are responsible for myelinating axons in the CNS (central nervous system), while Schwann cells myelinate axons in the PNS (peripheral nervous system). Vesicles are not directly involved in myelination, and unipolar cells and astrocytes do not myelinate axons at all.
