Figure 6

Sections of Hislopia malayensis budding stage 4. (a) Longitudinal section through the lophophoral base, foregut and ganglion. Asterisk marks the opening of the ganglion towards the atrium/foregut. (b) Section through the short tube-like elongation of the proventriculus to the esophagus. (c) Oblique section through the lophophoral base and parts of the digestive tract. (d) Oblique section through the lophophoral base and ganglion. Asterisk marks the opening of the lophophoral coelom to the remaining body cavity. Abbreviations: a - atrium, cw - cystid wall, es - esophagus, ggl - ganglion, int - intestine, itp - intertentacular pit, lb - lophophoral base, lc - lophophoral coelom, mpv - muscular sheath of the proventriculus, ph - pharynx, pt - peritoneum, pv - proventriculus, pve - tube-like extension of the proventriculus towards the esophagus, rm - retractor muscle fibres, sti - stomach-intestine junction, t - tentacle, tc - tentacle coelom, ts - tentacle sheath. Scale bar = 30 μm
