A co-worker has recently been diagnosed with multiple sclerosis. She appears to be still functioning normally at this time, but as the disease causes scar tissue to overtake the myelin sheath, it will slow the transmission of nerve impulses.

Question

Quizplus · Accepted Answer

Multiple sclerosis is a progressive disease that affects the nervous system, specifically the myelin sheath that surrounds and protects nerve fibers. As the disease progresses, scar tissue can overtake the myelin sheath, which slows down the transmission of nerve impulses. However, the severity and progression of the disease varies from person to person.
