Differentiation of the caudal muscle cells in the larva of Diplosoma macdonaldi" Cell Tissue Res (1983) 230:77-940302-766Xhttp://hdl.handle.net/1880/43422The larval muscle cells of Diplosoma macdonaldi contain subcortical and medullary myofibrils which are invested by fenestrated sheets of the sarcoplasmic reticulum. Cisternae of the sarcoplasmic reticulum are coupled with tubular invaginations of the sarcolemma. To appreciate better such uncommon features of cellular organization, six embryonic stages were selected for an ultrastructural study of myogenesis. The proliferative, synthetic, and elaborative phases of myogenesis were represented by embryos ranging from neurulae to prehatching larvae.1847073 bytesapplication/pdfenBiologyAscidian larvaEmbryologyMyogenesisSomatic striated (skeletal) muscleUltrastructureUltrastructure and Differentiation of Ascidian Muscle II.
