Description

Detail of the filamentous reticulum along the left side of the cytopharynx from which cytopharyngeal ribbons arise next to its nodes. Quadrulus associated ribbons lie between the filamentous reticulum and the alveoli. Cytopharyngeal ribbons have discoidal vesicles stacked against their surfaces. TEM taken on 4/10/74 by R. Allen with Hitachi HU11A operating at 75kV. Neg.18,500X. Bar = 0.2µm.

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. The negative was printed to paper and the image was scanned to Photoshop. This digitized image is available for qualitative analysis. There is a high resolution version of this image in the library (CIL:39166) which is available for quantitative analysis. Additional information available at (http://www5.pbrc.hawaii.edu/allen/).
