(1. marks for quality of response and inclusion of details.

) The myelin sheath is a fatty coating which is wrapped nigh the axon of many neurons, It provides insulation to the axon and improves its expertness to conduc t neural impulses. By acting as a conductor, the myelin sheath allows the neural impulses to skip widely lay gaps in the neuron, greatly speeding n eural transmissions. Multiple sclerosis des! troys the myelin sheath of many neuron s. People low-down with MS have difficulties controlling their muscles and often suffer adept visual sense problems because their neurons are unable to operate at normal efficie ncy. ib.
