The proximal ends of the basal bodies of a cirrus are embedded in a perforated plate of electron opaque material. Microtubules arise from this opaque material. A secondary fretwork of connections binds the basal bodies midway along their length. 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 7/24/69 by R. Allen with Philips 200 operating at 60kV. Neg. 12,400X. Bar = 0.5µm. A print of the negative was scanned and processed in Photoshop. This image is best used for qualitative analysis. A high resolution image (CIL:9805) is available for quantitative analysis.
