Two parasomal sacs that are oriented perpendicular to the basal bodies. The top parasomal sac has a clathrin cage around it's coated pit area. The P-face of the plasma membrane has some IMPs, particularly around the neck of the basal body. Alveoli contain some non-etchable material. Striated bands are anchored to the cytosolic face of the inner alveolar membrane to which an inconspicuous epiplasm is bound. Fractured kinetodesmal fibers show evidence of longitudinally ordered packing of subunits even though cross striations are more prominent in thin sections. Additional interpretation is available at Chapter 8, Image 9 at the link below. TEM taken on 6/4/91 by R. Allen with Zeiss 10A operating at 80kV. Neg. 24,800X. Bar = 0.2µm. A print of the negative was scanned and processed in Photoshop. This image is best used for qualitative analysis. A high resolution image (CIL:12634) is available for quantitative analysis.
