CLSM of phalloidin stained muscle system and light microscopy of Limnognathia maerski . Anterior end is positioned left on all pictures. A: Ventral view, Z-stack of the ventral portion, showing only the muscle system. B: Single section showing CLSM of the dorsal muscle system and the contour of the specimen, visualized with transmitted light. C: Synapsin2 staining of L. maerski, maximum intensity projection of a dorsal substack. Lines show the border of the dorsal cells to which the dorso-ventral muscles attach (illustrated in Figure 4B). advm, anterior dorso-ventral muscles; alm, anterior lateral muscle; cpm, ciliated adhesive pad muscle; fmm, front margin muscle; ldm, lateral dorsal muscle; lvm, lateral ventral muscle; mdm, median-dorsal muscle; mvm, medio-ventral muscle; mn, muscle network; pvm, paramedian ventral muscle; pvm2, posterior lateral muscle; sav1,2, small anterior ventral longitudinal muscles; tdvm, trunk dorso-ventral muscles; vpm, ventral pharyngeal muscles.
