A row of large IMPs bordering parts of the plates are visible. Two parentheses-shaped empty trichocyst docking sites are also present and one ring surrounding pits where the rosette IMPs have been rem...

Views of a striated band linked to the epiplasm on the ridge slopes and the intermembrane space between the plasma membrane and alveolus space inside the alveolus. TEM taken on 6/6/91 by C. Schroeder ...

The micronuclear separation spindle. Nuclear pores are not empty perforations but are closed by nonetchable material. The separation spindle must elongate as microtubules lengthen and/or slide against...

A view of the ER on which IMPs are organized into lines, arcs, and circles indicating organization of proteins within the ER membrane and possibly peripheral proteins attached to its cytosolic surface...

Tangential fractures through mature trichocysts. The planes in the paracrystalline stacks are exposed. The body is laced to the membrane but such associations must be severed when the trichocyst is di...

Mouse skeletal muscle. This image depicts a transmission electron micrograph of 1 month old mouse skeletal muscle tissue from the EDL muscle. Note the highly ordered organization of the contractile ap...

A fracture of an apparently fully formed trichocyst showing that the body of paracrystalline material fills the organelles lumen and is bound to the membrane by a loose array of threads. The membrane,...

The tip of the trichocyst does not expand but remains nail shaped and remains bound to the elongated shaft. TEM taken on 6/7/88 by C. Schroeder with Zeiss 10A operating at 80kV. Neg. 19,800X. Bar = 0....
