Stacks of 4 or 5 kinetodesmal fibers occupy the longitudinal ridges in a cross-sectioned cell. The kds lie along the right side of each ridge (cell’s left side), and as the kds are tapered, the smallest cross sections lie closest to the ridge tip and these sections are also closest to the distal tips of the kds. Such a kd arose from basal bodies 4 or 5 cortical units posterior to the plane of the cross-section. Lateral ridges do not contain kds. TEM taken on 12/28/74 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 17,500X.
Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm thickness.The raw negative was scanned with an Epson Perfection V750 Pro and this high resolution image is best used for quantitative analysis.
