Compare the functioning of a Schwann cell to an oligodendrocyte.

A. Both produce myelin, but Schwann cells wrap their myelin around astrocytes, while oligodendrocytes wrap myelin around axons in the CNS.
B. Both play key roles in the blood-brain barrier.
C. Schwann cells myelinate peripheral axons; oligodendrocytes myelinate CNS axons.
D. Both produce factors that regulate the activity of astrocytes.



Answer :

Final answer:

Schwann Cells produce myelin in the peripheral nervous system while Oligodendrocytes produce myelin in the central nervous system, both crucial for nerve signal transmission.


Explanation:

Schwann Cells are found in the peripheral nervous system and produce myelin sheaths for PNS axons. They wrap around a single axon segment.

Oligodendrocytes are located in the central nervous system and produce myelin sheaths for CNS axons. They can myelinate multiple axon segments.

Both cells play crucial roles in insulating axons and facilitating efficient nerve signal transmission.
