Figure 6

Semi-thin (a, b) and ultra-thin sections (c-f) of the cerebral ganglion of Paludicella articulata . a) Semi-thin cross section through the entire zooid, demonstrating the situation of the cerebral ganglion within the zooid b) Detailed view of the ganglion lumen in a retracted situation. c) TEM micrographs of the ganglionic tissue. d) Overview of the cerebral ganglion in a retracted polypide with its small lumen. e) Cell connections via adherens junctions in the area of the lumen within the cerebral ganglion. f) Adherens junctions of a nerve cell adjoining the fluid-filled lumen. Abbreviations: bc, body coelom; c, cystid; ca, cardia; cae, cecum; cg, cerebral ganglion; ecm, extracellular matrix; gl, ganglion lumen; itp, intertentacular pit; lc, lophophore coelom; ph, pharynx; pm, parietal muscle; tc, tentacle coelom; asterisks, cell-cell connections via adherens junctions.
