Question

Quizplus · Accepted Answer

Multiple sclerosis is a disease that leads to the degeneration of the myelin sheath, a protective covering around nerve cells that helps with the conduction of electrical impulses. Without this coating, nerve impulses can be disrupted, leading to muscle weakness, motor coordination issues, and balance problems.
