A high resolution image of a tangential section through the cell’s surface show the pairs of basal bodies in cross section. The ends of kinetodesmal fibers point anteriorly in the cell, the postcili...

b-tubulin immunogold labeled microtubules arise from the apex of the cytoproct ridge and pass to the spent DV membrane. Trichocyst and trichocyst tip included in this image. TEM taken on 7/5/96 by R. ...

A tangential section through the cell’s surface show the pairs of basal bodies in cross section. The ends of kinetodesmal fibers point anteriorly in the cell, the postciliary ribbons arise from the ...

Following discharge, remnant trichocyst membrane does not appear to directly enter the trans Golgi network for reuse in new trichocyst formation. Rather the HRP will be transferred to lysosomes (not s...

A high resolution micrograph showing four parasomal sacs in longitudinal section each at the base of a surface depression. Trichocysts extend into each lateral ridge (lateral ridges do not have kineto...

Four parasomal sacs showing them in longitudinal section each at the base of a surface depression. Trichocysts extend into each lateral ridge (lateral ridges do not have kinetodesmal fibers). Bulbous ...

In this micrograph of a developing organelle, the trichocyst membrane is intact but does not bear the glycocalyx seen on the luminal side of the lysosomal membrane that lies nearby. The flocculant mat...

Electric shock causes massive trichocyst discharge and results in a large accumulation of HRP-labeled vesicles at the ectoplasmic/endoplasmic interface (at the level of the internal ends of the undisc...

Developing trichocyst containing a paracrystalline core surrounded by amorphous material and an autophagosome containing mitochodrion. TEM taken on 1/25/74 by R. Allen with Hitachi HU11A operating at ...

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...
