Schematic representations of acetylated α-tubulin-LIR, Serotonin-LIR and FMRF-LIR in Echinoderes. a-c Lateral overviews with the head extended. a’-c’ Ventral views of the head. Anterior is to the top in all panels. b-c’ 5HT-LIR and FMRF-LIR are overlaid upon a background of acTub-LIR (gray). The number of 5HT+ and FMRF+ somata (vncs) along the ventral nerve cord (b, c) varies among specimens and are representative here. Note the approximate orientations and arrangements of 5HT+ ventromedial somata (b’) and FMRF+ bipolar cells (c’) relative to neural rings of the neuropil. Abbreviations: bpc, FMRF+ bipolar cells; cne, convergent neurites; cnr, complete neural ring; gn, gonad neurite; inr, incomplete neural ring; lnb, longitudinal neurite bundle; mcnr, mouth cone nerve ring; mdsn, middorsal spine neurite; ncn, neck circular neurite; nen, nephridial neurite; np, neuropil; pen, penile spine neurite; sdn, subdorsal longitudinal nerve; tn, transverse neurite; tsn, terminal spine neurite; vln, ventrolateral nerve; vms, 5HT+ ventromedial somata; vnc, ventral nerve cord; vncs, ventral nerve cord FMRF+ somata
