Fig. 2From: Comparative morphology of the nervous system in three phylactolaemate bryozoansLophophore innervation in Cristatella mucedo visualized after staining with antibodies against acetylated tubulin (a, b arm view from above, double distal dichotomy of the main radial nerves not seen in this plane; c, d lateral view, double dichotomy of the main radial nerves well seen in d). a Proximal part of the arm with basal parts of the tentacles (mouth region seen on the left); b distal part of the arm; c distal part of the arm with basal parts of the tentacles (lophophore horn is behind the main radial nerves); d fronto-lateral part of the lophophore showing basal parts of tentacles. Abbreviations: arn, additional radial nerve; brn, basal radial nerve; dn, distal branches of main radial nerve; fn, tentacle frontal nerve; lh, lophophore nerve tract (horn); ln, lateral branches of main radial nerve; m, mouth; mrn, main radial nerve.
