A longitudinal section of an oral basal body and cilium with the attachment of a bundle of microtubular filaments and a rod that covers the proximal end of the basal body. A layer of filaments underlies the corrugated lips and lamellae extend from these lips. The oblique section through the bundle of microtubules exposes the periodic appearance of the bundle. Parasomal sacs, discoidal vesicles, mucocysts, early endosomes, and toxicysts are seen in this cortical section. 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 5/28/69 by R. Allen with Philips 300. Neg. 14,800X. 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:2872) is available for quantitative analysis. Additional information available at (
