Fig. 7 in Ultrastructural Studies on a Model Tintinnid - Schmidingerella meunieri (Kofoid and Campbell, 1929) Agatha and Strüder-Kypke, 2012 (Ciliophora). I. Somatic Kinetids with Unique Ultrastructure

Fig. 7. Schematic drawing of the anterior portion of two adjacent kineties in the left ciliary field of Schmidingerella meunieri compiling all observations from transmission electron micrographs. The 20°–30° angles of the kinetids are not considered. The kineties are monokinetidal, except for one anterior dikinetid. The microtubules of the connecting (ribbons I) and postciliary ribbons form a network. I–III, extraordinary microtubular ribbons I–III; AP, axosomal plate; Axn, axoneme; Axs, axosome; CC, cytoplasmic connection; CG, core granule; CM, cortical microtubules; CP, ciliary pit; CT, central microtubules; EC, electron-dense cuff; Kd, kinetodesmal fibril; P, perilemma; Pc, postciliary ribbon; T, transverse ribbon.
