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 in...

Images of desmosomes from conventional EM and freeze fracture preparations show transmembrane filaments that link two hemidesmosomes. Upper: section of a cell boundary in the ciliary epithelium of th...

This is one of a group of four images in Figure S5 in Apaja et al., JCB 2010, that support the conclusion that the WT vasopressin type2 receptor (V2R) and the V2R W164S mutant (that causes nephrogenic...

This section of Conchophthirus is at the edge of the cortex showing the striated fibers and microtubules that attach to ciliated basal bodies. In particular, enlarged glancing longitudinal views of bo...

A view of early endosomes with coated evaginations at their margins. TEM taken on 8/15/67 by R. Allen with Philips 200 operating at 60kV. Neg. 19,200X. Bar = 0.5µm. The negative was printed to paper ...

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...

The P-face of the ciliary membrane at the base of the cilium has 9 triple rows of IMPs in register with the 9 doublets of the internal axoneme. It is thought that these IMPs may be sites of calcium in...

The spasmoneme contains membranous tubules that are known to store calcium (see Favard, P. and N. Carasso, J. Microscopie 3:671-696, 1964) and to be modified ER. The alveoli only partially surround th...

Freeze fracture of the plasma membrane and outer alveolar membrane of the pellicle of V. microstoma. The surface of Vorticella is encircled by rings which follow the septa of underlying alveoli. In th...

A high resolution image of a cortical monokinetid showing the basal body as well as postciliary and transverse microtubular ribbons. Slender endosomal vesicles accumulate near the bottom of a parasoma...
