Description

High resolution view of an oblique section shows the transverse aspect of basal bodies/cilia within one pectinelle of one of the two ciliary girdles of Didinium. Two ribbons of microtubules and a short kinetodesmal fiber arise from the proximal margin of each basal body. These may correspond to transverse microtubules and postciliary microtubules of other ciliates. Tips of parasomal sacs are also present. Microtubular ribbons under the alveoli seem to arise from extensions of the postciliary microtubules. TEM taken on 5/9/69 by R. Allen with Philips 300 operating at 60kV. Neg. 14,800X. The raw film was scanned with a Nikon Coolscan 9000ED. This image is 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.
