Question
Which glial cell type is responsible for forming the myelin sheath in the central nervous system?
Correct Answer
Option B is the correct answer.
Detailed Explanation
Oligodendrocytes are glial cells in the central nervous system (brain and spinal cord) that extend processes to wrap around multiple axons, forming the myelin sheath.
Hint
In the PNS, this job is done by Schwann cells, which only myelinate one axon.
