Basal bodies are supported by three fiber systems, a striated kinetodesmal fiber that arises from the proximal end of the basal body and curves upward and anteriorly within the longitudinal ridge to the cell’s right side of a row of basal bodies. Extending posteriorly and also curving up into the longitudinal ridge is a ribbon of postciliary microtubules. The kd may extend past several more anterior basal bodies but the postciliary ribbon does not extend beyond the next posterior basal body or pair of basal bodies in the kinety. Only the more posterior of the two basal bodies within a single depression is associated with the ends of these two accessory structures. An indentation of the plasma membrane, the parasomal sac, lies to the cell's right of each basal body or pair of basal bodies. TEM taken on 1/5/73 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 19,500X. Bar = 0.2µm. 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 version of this image (CIL:12068) is in the library and available for quantitative analysis. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm thickness.
