Image of a dikinetid of Euplotes shows the transverse microtubular ribbon as well as a postciliary ribbon extending from the posterior basal body. Vesicles containing electron opaque bodies are typica...

Section of Halteria showing the extension of buccal cavity and the cytopharynx passing into the cell. Vesicles accumulate at the cytopharynx next to the lamellae. These vesicles may be homologs of dis...

Lamellae of cytopharynx in the opisthe of a dividing cell. This cytopharynx is not yet functional and lacks most of the medium dense vesicles that accumulate between the lamellae. Toxicysts are presen...

A glancing view of the cortex of Conchophthirus reveals details of cortical structure. This includes the nature of the cell membrane and the alveolar membranes that reside immediately below the surfac...

An image of the cortex of Tetrahymena showing a longitudinal microtubular ribbon sandwiched between the alveoli and the epiplasm in the crest of the pellicular ridge. A parasomal sac, the distal end o...

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 ...

A glancing view of the cortex of Conchophthirus reveals details of cortical structure. A near serial section with CIL:39239. This includes the nature of the cell membrane and the alveolar membranes th...

A transverse section of the cortex of Conchophthirus curtus reveals details of cortical structure. This includes the nature of the cell membrane and the alveolar membranes that reside immediately belo...

An image of the pellicle of Didinium, in cross section of a non-dividing cell, has a plasma membrane with a distinct glycocalyx on its external surface and a flattened alveolar sac system. Under the a...

The undulating membrane is composed of two rows of basal bodies but only the outer row is ciliated. Both basal bodies are fully formed but only the ciliated member has an axosome and 9 + 2 axoneme. Th...
