Fig. 12

Pallial musculature in Nodipecten nodosus juveniles. Histological sectioning (b) and staining with phalloidin combined with confocal laser scanning microscopy (ce). a Schematic representation of the mantle margin, ventral to the top; the arrow points to the view of figures ce. b Detail of muscle fibers in the mantle and dense muscular bundles in the inner mantle fold. The plane of section is the same of figure a. Toluidine blue and basic fuchsin. c Overview of the mantle margin, including the inner mantle fold and its tentacles. Pallial muscles are radially distributed throughout the mantle margin and margin-parallel muscles are present within the inner fold. Nuclei stained in blue by DAPI; lateral view, ventral to the top. d Detail of the mantle margin radial musculature, as indicated in the inset of c, showing a combination of apparently non-striated (arrows) and striated myofibers (arrowheads). e Detail of the inset observed in c showing the arrangement of margin-parallel striated muscle fibers within the inner fold, more densely arranged in the distal region of the fold. Nuclei stained in blue by DAPI. Abbreviations: if, inner mantle fold; ma, mantle; mm, mantle margin; pm, pallial muscles; te, tentacles
