Cross sections of basal bodies at the level of their attachments to the kinetodesmal fiber, the anterior basal body is attached by a thin bridge. The proximal ends of one postciliary microtubular ribbon and a transverse microtubular ribbon are next to the pair of basal bodies. Infraciliary lattice, post of lattice, and trichocyst tip are seen. TEM taken on 2/21/69 by R. Allen with Philips 300 operating at 60kV. Neg. 47,100X. 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 version of this image (CIL:12066) 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.
