Description

A view of the left side of the buccal cavity. It is covered by the plasma membrane, alveoli and a single partial layer of microtubules. Specialized cytoplasm lines the posterior end of this border. Oral ribs contain microtubular ribbons and interdigitate with alveolar tubes. TEM taken on 8/21/67 by R. Allen with Philips 200 operating at 60kV. Neg. 12,400X. Bar = 0.5µm. The negative was printed to paper and the image was scanned to Photoshop. This digitized image is available for qualitative analysis. An unprocessed, high resolution version of this image (CIL:34745) is in the library and available for quantitative analysis. Additional information available at (http://www5.pbrc.hawaii.edu/allen/).

Technical Details

Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm thickness. Additional information available at (http://www5.pbrc.hawaii.edu/allen/).
