Summary Introduction

To review:

The reason for the affected motor control when the myelin sheath is destroyed.

Introduction:

Multiple sclerosis is an autoimmune disease, in which the immune cells start attacking the myelin sheath covering on the axon of the neuron. Myelin sheath is an insulation layer that surrounds the axon of the neurons. It is mainly made up of fats and is white in color. In multiple sclerosis, the myelin sheath is damaged, resulting in the disruption in the electric signals. Certain symptoms include muscle weakness, double vision, and poor coordination.
