A high resolution image of a tangential section through the cell’s surface show the pairs of basal bodies in cross section. The ends of kinetodesmal fibers point anteriorly in the cell, the postciliary ribbons arise from the posterior right side of the posterior basal body of a pair and transverse ribbons arise from the left side of both basal bodies of a pair. The more anterior basal body of a pair is linked to the posterior basal body by a striated fiber and to the adjacent kinetodesmal fiber by a short filamentous connection (arrowhead). Parasomal sacs, infraciliary lattice, striated band, and trichocyst tips are evident. TEM taken on 1/12/73 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 14,900X. The raw film was scanned with an Epson Perfection V750 Pro. This image is best used 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.
