Fig. 9 Myoanatomy of a retracted polypide of an adult Pherusella sp. a Anal view of the lophophoral base. Volume rendering. Note the two buccal dilatators on a more proximal position, indicated by asterisk (*). b Oral view of retractor muscle and lophophoral base. Maximum intensity projection. c Distal view of musculature of the polypide. Maximum intensity projection. d Detailed view of retractor muscle shows f-actin fibers with a crossstriated pattern indicated by arrows. Maximum intensity projection. e Distal view of musculature of the polypide with particular focus on the longitudinal fibers proceeding along the esophagus and cardia. Volume rendering. Abbreviations: al – abfrontal lophophoral base muscle, bd – buccal dilatator, ca – cardia, cae – caecum, es – esophagus, f – funiculus, fl – frontal lophophoral base muscle, int – intestine, mo – mouth opening, ph – pharynx, phr – pharyngeal ring muscle, py – pylorus, rm – retractor muscle, tm – tentacle muscle, vm – "vshaped" lophophoral base muscle
