Sensory structures in Eudiplozoon nipponicum. A. General view of the forebody with its prominent mouth. White circles indicate some of the uniciliated sensory structures. SEM. B. General view of the forebody, showing the nervous system and distribution of sensory structures. White circles indicate innervation of some of the uniciliated sensory structures. CLSM, anti-α-tubulin-FITC. C. A more superficial optical section showing the distribution of sensory structures. White circles indicate examples of their innervation and white rectangles demark sensory cilia. CLSM, anti-α-tubulin-FITC/Hoechst. D-F. Uniciliated sensory structures in the forebody – without a tegumentary rim (D), with a subtle rim (E) and with a prominent rim (F). SEM. G-H. Uniciliated sensory structures interrupting the forebody (G) and hindbody tegument (H). TEM. I. Uniciliated sensory structure with a prominent tegumentary rim interrupting the forebody tegument. TEM. a – cilium anchoring, apm – apical plasma membrane, bl – basal lamina, black asterisk – basal body of the cilium, bpm – basal plasma membrane, c – cilium, cm – circular muscle fibres, d – desmosome, dc – dense collar, de – dendrite, m – muscles, mi – mitochondria, pnf – peripheral nerve fibres, r – raised rim, sb – secretory bodies, sc – syncytium, tc – transverse commissure, vn – ventral nerve cord
