Description

A high resolution view of a longitudinal section through the buccal cavity of the oral region showing portions of 3 membranelles (1, 2 and 3): each membranelle consists of 3 rows of cilia. The oral ribs are seen on the right side of the buccal cavity and are underlain by a filamentous reticulum and by the endoplasmic reticulum. A specialized cytoplasm covers the posterior left side of the buccal cavity and a single layer of microtubules covers the left side. TEM taken on 2/9/71 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 6,000X. The raw film was scanned with an Epson Perfection V750 Pro. This image is best used for quantitative analysis.

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/).
