The symptoms of MS can come and go. This is because multiple choice 1the astrocytes take on the job of making the myelin.the oligodendrocytes are constantly renewing their myelin sheaths, so they are able to temporarily repair some of the damage.the neurons themselves are making the myelin covering.the neurons are able to temporarily adapt to the absence of the myelin and use an alternate system of propagating neural impulses. 2. Triggers of acute episodes of MS include multiple choice 2all listed choices.infections.pregnancy.stress. 3. Most researchers believe MS results from a combination of genetic and environmental factors. One peculiar observation regarding environment is the fact that the incidence increases as one gets farther from the equator. multiple choice 3FalseTrue
