11. The primary lipid of myelin is a glycolipid called galactocerebroside. 12. The intertwining hydrocarbon chains of sphingomyelin serve to strengthen the myelin sheath. 13. The colour difference arises mainly from the whiteness of myelin . 14. Myelin prevents ions from entering or leaving the axon along myelinated segments.15. Myelin has two important advantages : fast conduction speed and energy efficiency.16. Multicomponent relaxometry ( MCR ) allow visualization and quantification of myelin content. 17. In the second group, myelin is abnormal and degenerates. 18. Monogalactosylceramide is the largest single component of the myelin sheath of nerves. 19. Cerebroside synthesis can therefore give a measurement of myelin formation or remyelination. 20. Myelin is a lipid covering that speeds the conduction of action potentials.
