Fig. 2 in Morphology and evolution of the nervous system in Gnathostomulida (Gnathifera, Spiralia)

Fig. 2 Schematic drawing of the nervous system in Gnathostomula paradoxa as inferred from tyrosinated tubulinlike immunoreactivity and CLSM. Central nervous system in red, short peripheral neurites and plexi in purple. a Entire body, dorsal structures. b Entire body, ventral structures. c Head and pharyngeal regions, dorsal structures. Two pairs of compound cirri (s2 and s4) are not shown. d Head and pharyngeal regions, ventral structures.
