The undulating membrane is composed of two rows of basal bodies but only the outer row is ciliated. Both basal bodies are fully formed but only the ciliated member has an axosome and 9 + 2 axoneme. The oral ribs each contain two microtubular ribbons of 4 and 2 microtubules respectively and alveoli lie between. TEM taken on 8/25/67 by R. Allen with Philips 200 operating at 60kV. Neg. 2,400X. Bar = 0.1µm. The negative was printed to paper and the image was scanned to Photoshop. This digitized image is available for qualitative analysis. An unprocessed, high resolution versions of this image (CIL:34746 & 34747) are available in the library for quantitative analysis.
