poetry lyrics:/ Wrote the vitamin-expert, "My thesis:/ B12's key in
 erythropoiesis./ Many systems protected./ Other functions affected?/ The health
 of the myelin sheath is."

Authors' Note: The myelin sheath is an envelope of lipid-rich material that wraps around peripheral nerve fibers, acting as a form of insulation; its development and maintenance is dependent on vitamin B12. Erythropoiesis is the formation of red blood cells that takes place in the bone marrow.
