In quick-freeze deep-etch preparations in which cells are slam frozen the pellicle and the plasma membrane tends to be flattened. The double rings are present but only the outer ring of IMPs stand out...

In a conventional freeze fracture view the membrane around the trichocyst tip is decorated with striations and IMPs. These decorations are found at the site where the trichocyst tip is associated with...

A view of cortical fibers except the observer is looking at a cross-sectioned cell as though from anterior toward the posterior end of the cell; in this view the kd sections are seen on the left side ...

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...

A high magnification view of the above septum in planar view and the septal pores that connect adjacent alveoli. The pores always lie next to the junction of the septum with the outer alveolar membran...

Striated band spanning the base of a longitudinal ridge (kinetodesmal fibers are seen in the ridge in cross section). The epiplasm appears absent from the top of the ridge or is replaced by two thicke...

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...
