description: This group of micrographs illustrate the ultrastructural characteristics of the middle layer of the three meningeal layers that cover the central nervous system The arachnoid cells contain abundant intermediate filaments that occupy a substantial volume of the cytoplasm. In some cells the intermediate filaments are organized into numerous coils of relatively uniform size and orientation. The coils appear to stack in loose hexagonal arrays (CIL:9301). The plasma membrane of these cells has many caveolae. Adjacent arachnoid cells are connected by large desmosomes. In this micrograph, large numbers of intermediate filaments are seen; they are evidently very close to the inner surface of the plasma membrane, where they insert into electron-dense desmosomal plagues. Images were recorded using a Philips EM301 TEM at 80 kv. Original glass plates were scanned and digitized using an Epson V750 flatbed scanner with a step size of 15 micrometers. This group of images complement those published in the reference below. Reference: Michaels, JE, Tornheim, PA. Cell Tissue Res. 236:693-697 (1984).

description: Image of the extracellular, non-contractile stalk of Opercularia coarctata that is formed from the scopula. Cylinders ('straws') of fibrous material in the lumen of the stalk are surrounded by an outer membrane-like sheath. The fibrous cylinders have diameters similar to those of basal bodies. TEM taken on 6/10/69 by R. Allen with Philips 300 operating at 60kV. 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:7455) is available for quantitative analysis. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm thickness.

description: Paramecium multimicronucleatum - Video of the Contractile Vacuole Complex. Measuring membrane tension of the in vitro CV. To measure the build up of tension by the CV membrane an in vitro CV surrounded by a thin layer of cytosol containing ATP was mounted on the tip of a holding pipette and a thin glass rod or sphere, mounted on the tip of a microcantilever, was rested on the CV's membrane. During rounding of the CV the sphere or glass rod was pushed upward which is then recorded as an output voltage of a position sensor. This can be converted into force which, in turn, can be converted into tension. The tension of the rounded CV membrane increased 35-fold over the tension of the relaxed membrane. A DVD resolution version of this is available at CIL:10409.
