Fig. 7From: The neuroanatomy of Barentsia discreta (Entoprocta, Coloniales) reveals significant differences between bryozoan and entoproct nervous systemsScheme of the organization of the nervous system of (a) colonial and (b) solitary Entoprocta. Color legend: orange, tentacle cords and nerves; green, laterofrontal nerve; pink, abfrontal nerve; purple, ganglion; light-green, atrial nerve ring of solitary species; light blue, paired oral nerves of solitary species and the first pair of lateral nerves of colial species; dark blue, paired lateral nerves; mint, paired aboral nerves; lightpink, arcuate nerves of colonial species; yellow, stomach nerve of solitary species; red, peripheral calyx nerves; brown, serotonin-like immunoreactive perikarya connected with esophagus. Abbreviations: an, abfrontal tentacle nerve; arc, arcuate nerve of colonial species; g, ganglion; lfn, latero-frontal tentacle nerve; ln, lateral nerve; ln1, first lateral nerve of colonial species; nr, atrial nerve ring of solitary species; on, oral nerve of solitary species; pn, peripheral calyx nerves; pk, serotonin-like immunoreactive perikarya connected with esophagus; stn, stomach nerve of solitary species; tc, tentacle cord; tn, tentacle nerveBack to article page
