MS plaques can form in which parts of the central nervous system?

Explanation:
MS plaques arise from demyelination within the central nervous system. While white matter is the most common site due to the abundance of myelinated axons, plaques can also involve gray matter and the optic nerves—both are CNS tissue and can be affected by the same autoimmune process. Peripheral nerves, which are myelinated by Schwann cells, are not typically involved in MS. Therefore, plaques can form in white matter, gray matter, and the optic nerves.
