Which of the following statements is TRUE?
A) In the central nervous system Schwann cells serve as guideposts to show axons where to terminate when regeneration occurs.
B) In the peripheral nervous system Schwann cells serve as signposts to guide axons to their appropriate end points.
C) Schwann cells cannot help damaged axons,because neither nervous system can regenerate.
D) Schwann cells are present only in the developing organism and thus have nothing to do with regeneration.

Question

Quizplus · Accepted Answer

Schwann cells are the myelinating cells in the peripheral nervous system and they play a crucial role in guiding the regenerating axons to their appropriate targets. In contrast, in the central nervous system, oligodendrocytes are the myelinating cells and they do not facilitate axon regeneration in the same way Schwann cells do.
