A high resolution image of a dikinetid in cross section near its proximal end. A postciliary ribbon and a transverse ribbon are seen. A short kinetodesmal fiber buds from the side of the kinetid. Coat...

A high resolution image of a section through the cytopharynx of Coleps showing the corrugated lips containing lamellae surrounding the atrium of the buccal cavity. Rods composed of hexagonally packed ...

High resolution image of longitudinal section of somatic cilia showing the axoneme, basal body, and attached fibrous and microtubular elements. Adjacent digestive vacuoles and cortical cytoplasm evide...

A high resolution micrograph showing the striated kinetodesmal fiber extending to the pellicle from the basal body where it terminates against the epiplasm. A bundle of microtubules extends into the c...

High resolution image of the nucleoli of the macronucleus. Nucleoli have a core of DNA that contains the genes that are transcribed into ribosomal RNA. Assembly of the ribosomal subunits from this pro...

A High resolution micrograph of tetrahymena showing a transverse ribbon starting from the anterior right side of the proximal end of a basal body (out of section plane) and crossing under the pellicle...

A tangential section through the buccal cavity showing the close spacing of the cilia in the undulating membrane and 3, presumably nonciliated basal bodies, in the inside row. Accessory microtubular r...

The scopula, stalk-forming region, is outlined by a circle of basal bodies that produce short modified cilia. Other basal bodies lie within this circle. The sheath is secreted outside the circle of ci...

Mitochondria of Vorticella convallaria like other ciliates, have tubular cristae arising from their inner membranes. However, they also have a bundle of filaments (DNA?) that extend through the center...

The deep fiber is associated with the cytopharyngeal membrane (see Smith and Bunse, Trans. Am. Microsc. Soc. 102:264-271, 1983). This membrane has acidosome-like vesicles docked at its cytosolic surfa...
