Details of lophophore innervation and cerebral ganglion in Cristatella mucedo. a, b cerebral ganglion and lophophoral nerves (view from above, bipolar neurons situated near oral and lophophore arms tentacle bases, in some of them the main neurites merge before joining main radial nerves in a) (staining with antibodies against serotonin); c tentacle tips with sensory bipolar neurons which central neurite descends with tentacle frontal nerve (staining with antibodies against FMRFamide); d innervation of lophophore arm (view from above, bipolar neurons situated near tentacle bases, arrows point to the places where additional radial nerves join main radial nerves) (staining with antibodies against serotonin shown in green and against α-tubulin in violet). Abbreviations: arn, additional radial nerve; bn, bipolar neurons; bsn, bipolar sensory neurons situated near the tentacle tip; cnr, serotonin-like immunoreactive neurites of circumpharyngeal nerve ring; co, commissure; dn, distal branches of main radial nerve; lh, lophophore nerve tract (horn); mrn, main radial nerve; n, neuropil of cerebral ganglion.
