Magelona mirabilis, lateral organ. a,b histological cross sections (5 μm), Azan staining. c,d: SEM. a: The lateral organ is located between the neuro- and notopodium (noto). A nerve (ner) connects the sensory cells of the lateral organ to the ventral nervous system (vns). ci: cilia. b: Sensory cells which bear long cilia (ci) are connected to a nerve (ner) by neurites (ne). bl: basal lamina; so: somata. c: The lateral organ consists of a patch of elongated cilia between the neuro- (neur) and notopodium (noto). d: higher magnification of C: Cilia (ci) of the lateral organ are elongated
