Body wall muscles in oligochaetes

Longitudinal body wall muscles in tubificids, enchytraeids, lumbriculids, haplotaxids and lumbricids are always histologically and ultrastructurally distinguishable from one another. Some structural peculiarities, as those typical of lumbriculids, may be used as taxonomic tools. The longitudinal bod...

Zusammenfassung:Longitudinal body wall muscles in tubificids, enchytraeids, lumbriculids, haplotaxids and lumbricids are always histologically and ultrastructurally distinguishable from one another. Some structural peculiarities, as those typical of lumbriculids, may be used as taxonomic tools. The longitudinal body wall muscles in all oligochaetes belong to slow and fast contracting fibre types. Two possible phylogenetic patterns for the formation of slow fibres are discussed.
