In addition to plates the plasma membrane contains IMPs on its P-fracture face in ring or parenthesis shape at sites of trichocyst secretion. A ring actually consists of two circles of IMPs and signif...

This figure shows the connection between the peristome and the food vacuole forming zone where the alveoli end. The cytostome is the opening that connects these two zones. TEM taken on 6/13/69 by R. ...

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...
