Question

Quizplus · Accepted Answer

The sensory loss and muscle weakness associated with multiple sclerosis are a consequence of demyelination, which is the damage or loss of myelin sheaths around axonal fibers. This leads to disruptions in nerve impulses and communication between neurons, resulting in various symptoms associated with MS.
