Cross sections of striated bands and infraciliary lattice arms. Filaments of the striated bands are less densely packed than the infraciliary lattice. Kinetodesmal fibers and postciliary microtubules ...

High resolution image of Didinium (non-dividing) has a massive cytopharynx at its anterior end that takes the shape of a cone-shaped proboscis when closed. This cytopharynx contains numerous lamellae ...

The contractile vacuole pore is supported on its cytosolic side by a coil of microtubules and other microtubules extend from the pore to the CV membrane. The plasma membrane and CV membrane cover the ...

Didinium nasutum. A tangential view of the surface of a non-dividing cell shows several ribbons of microtubules between the alveolar sac and the epiplasm. The thick fibrous layer associated with the e...

Freeze fracture image of the E-face of rat bladder lumenal membrane. The lumenal surface of these epithelial cells is composed of plaques separated by interplaque regions. Within the plaques are hex...

This high resolution micrograph of Paramecium multimicronucleatum is adapted with permission from Fig. 1 in J. Cell Biol. 49:1-20, 1971. Paramecium is covered with cilia which arise from regular surfa...

A transverse section near the mid region of the oral proboscis of Didinium. This micrograph shows the extrusive organelles of the mucocysts adjacent to the plasma membrane and the toxicysts. The pexic...

A thin cryosection of Vorticella exposed to a rabbit polyclonal antibody to alpha-centrin and then to gold conjugated to anti-rabbit IgG. The gold indicates that the myoneme contains alpha-centrin. Th...

This freeze fracture view of the pellicle of V. microstoma near the aboral end of the zooid shows the region where the width of each circumferential alveolus is narrower and thus the strings of fractu...
