A high resolution micrograph of the monokinetids (single somatic basal bodies) of Coleps hirtus bear an anteriorly directed striated fibrous kinetodesmal fiber and a posteriorly directed ribbon of postciliary microtubules that arise from the posterior side of each basal body. Both pass to the same side of the row of basal bodies. Transverse microtubules arise from the anterior side of the basal body and pass to the other side of the row of basal bodies. These structures presumably give support to the twisting movements of the beating cilium. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm thickness. TEM taken on 5/23/69 by R. Allen with Philips 300 operating at 60kV. Neg. 14,800X. The raw film was scanned with an Epson Perfection V750 Pro. This high resolution image is suitable for quantitative analysis Additional information available at (
