As part of a systematic study of the evolution of the nervous system, the lipid composition of the ventral nerves of earthworms was examined. The nerve axons are wrapped in copious layers of loosely bound membrane, superficially resembling the myelin sheath of vertebrates. However, neither galactocerebroside nor sulfatide, both of which are considered to be markers for myelin, was present, and only traces of glucocerebroside, which is abundant in shrimp nerve, were detected. The lipids were… CONTINUE READING
