Question

Quizplus · Accepted Answer

Demyelination is the gradual reduction in myelin, which can occur due to a variety of conditions such as multiple sclerosis, leukodystrophies, and certain viral infections. It can affect both Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system. Options A and B are incorrect as they describe the opposite of demyelination. Option D and E are also incorrect as both Schwann cells and oligodendrocytes can be affected by demyelination.
