The neuropathology of multiple sclerosis is primarily characterized by:

C)accumulations of myelin around cell bodies secondary to malfunctioning myelin-producing cells.
D)small neoplasms distributed throughout the nervous systems.

Question

Quizplus · Accepted Answer

Multiple sclerosis is a demyelinating disease, meaning it involves the destruction of myelin—the protective covering around nerve fibers in the brain and spinal cord. The destruction of myelin is patchy and widespread, leading to the formation of scars (sclerosis). There may also be some degree of axonal damage and inflammation. Vascular damage or neoplasms are not characteristic of multiple sclerosis. Accumulations of myelin around cell bodies do not occur in MS.
