From: Trapped in freshwater: the internal anatomy of the entoproct Loxosomatoides sirindhornae
3D reconstruction of the central nervous system of Loxosomatoides sirindhornae with peripheral nerves, part of the nephridial system and mesenchymatous cells of the body cavity. Only a small part was reconstructed to demonstrate the complexity of these organ systems. (a) oblique-frontal view without mesenchymatous cells displayed. Note both terminal ducts joining above the central nervous system and opening by the single nephridiopore. (b) View from more frontally showing the complex web of mesenchymatous cells entangling the nervous and nephridial system. Close to the edge a couple of vesicular mesenchymatous cells are shown. (c) Aboral view of the nervous and nephridial system showing nerve trunks emanating from the central nervous system. (d) Close-up of the central nervous system and main nerves. Colors: Yellow - nervous system, purple - nephridial system, blue - flame bulbs/terminal organs, red - mesenchymatous cells, turquoise - vesicular mesenchymatous cells. Abbreviations: afn - atrial floor nerves, cn - nerve to calyx, cns - central nervous system, ed - efferent ducts of the nephridial system, fb - flame bulbs/terminal organs, ln - nerves innervating the lateral sides, mc - mesenchymatous cell, np - nephridiopore, sn - nerves to stalk, td - terminal duct, utd - unpaired terminal duct, vmc - vesicular mesenchymatous cell.
