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 i...

Septa of bordering alveoli when lying in the plane of section exhibit pores at their outer margins closest to the plasma membrane. This shows that there is physical continuity between the lumens of al...

In this image a portion of the true surface of the plasma membrane is exposed where the culture medium has been etched away. The IMPs of the plates can also be viewed less distinctly on the true surfa...

Hela cells transiently transfected with EGFP-GL-GPI show the organization of the membrane thru the distribution of GPI anchored protein. This image is the z stack that accompanies the related maximu...

A cell with a flat alveolar sac system. It is not clear why some cells have expanded alveoli and others have flattened alveoli. Cacodylate buffered fixative. TEM taken on 2/3/69 by R. Allen with Phil...

Electron micrograph of a nerve from the mesentery of a rat shows groups of unmyelinated axons wrapped by deeply invaginating Schwann cells in cross section. Surrounding the Schwann cell wrapping is a ...

Freeze fracture image of the surface ridges at the anterior end of the cell where kineties to the right and left sides come together at an angle at the anterior suture tip. In this area are numerous p...
