Figure 5From: The metameric pattern of Hypsibius dujardini(Eutardigrada) and its relationship to that of other panarthropodsLateral muscle anatomy of H. dujardini as revealed by phalloidin staining. Lateral muscle attachment sites are labeled following the system of Halberg et al. [54]. Anterior is to the right. Scale bars equal 25 μm. (A) View of longitudinal musculature. Lateral attachment sites are circled. Muscles labeled `ii' extend from ventral attachment sites to longitudinal attachment sites. Intermediate attachment sites a and b are visible in the ventral anterior and muscles labeled `a' attach to these. (B) Scanning electron micrograph showing cuticular depressions associated with longitudinal attachment sites. Abbreviation: le, leg; ph, pharyngeal bulb.Back to article page
