Schematic overview of the neuro-muscular system at the lophophoral base in Cinctipora elegans. a Nervous system. The tentacle innervation and outer nerve ring are only shown on the left side, and the tentacle sheath and visceral innervation on the right b Muscular system of the lophophoral base and pharynx. Abbreviations: af – abfrontal neurite bundle of the tentacle, afm – abfrontal muscles of the lophophoral base, bd – buccal dilatators, cg – cerebral ganglion, con – circum-oral nerve ring, fm – frontal muscles of the lophophoral base, lf - latero-frontal neurite bundle of the tentacle, lg – lateral ganglia, lvn – latero-visceral neurite bundle, mf – mediofrontal neurite bundle of the tentacle, mln – medio-lateral visceral neurite bundle, mvn – medio-visceral neurite bundle, onr – outer nerve ring, ph – pharynx, pm – proximal lophophoral base muscles, prm – pharyngeal ring muscles, tsn – tentacle sheath neurite bundle
