ABSTRACT: Whole mount preparations of juvenile Cadlina laevis aged 2–4 months after hatching were examined by immunocytochemistry and histochemistry in conjunction with confocal laser microscopy to study the architecture of the digestive system, its musculature and distribution in the digestive system of catecholamine-containing, 5-HT and FMRFamide-immunoreactive (im) nervous elements. The largest number of catecholamine-containing and FMRFamide-im nervous elements was found in the wall of the pharynx, the stomach and the digestive gland. The 5-HT-im innervation was observed primarily in the pharyngeal region of the digestive system. Catecholamine-containing and FMRFamide-im receptor cells were revealed in the oral velum around the mouth.
