Paramecium multimicronucleatum is covered with cilia which cilia arise from regular surface depressions roughly rectangular in shape. This image is adapted with permission from Fig. 1 in J. Cell Biol....

Euplotes sp. (eurystomus ?) is a hypotrich. This ciliate has a few rows of dorsal cilia as well as specialized clumps of cilia called cirri on its ventral side and a complex of membranelles involved i...

A view of the entry to the oral apparatus of the green Trichodina that lives on the surface of a freshwater snail collected in central Illinois. In this view the haplokinety and the polykinety of the ...

An image image of the multiple membrane systems at the cortex of ciliates. Thickened alveolar densities partially coat the alveolar membrane within the alveoli which underlie the plasma membrane of ci...

This high resolution micrograph of Paramecium multimicronucleatum is adapted with permission from Fig. 1 in J. Cell Biol. 49:1-20, 1971. Paramecium is covered with cilia which arise from regular surfa...

A high resolution micrograph of the monokinetids (single somatic basal bodies) of Coleps hirtus bear an anteriorly directed striated fibrous kinetodesmal fiber and a posteriorly directed ribbon of pos...

A longitudinal section of an oral basal body and cilium with the attachment of a bundle of microtubular filaments and a rod that covers the proximal end of the basal body. A layer of filaments underli...

This image of a cortical monokinetid shows the basal body as well as postciliary and transverse microtubular ribbons. Slender endosomal vesicles accumulate near the bottom of a parasomal sac which is ...

A view of cross-sectioned rows of basal bodies in Nassula exposing the absence of cilia. Only a few basal bodies may have attached cilia as seen by the few cilia present in the upper right row. Basal ...

A view of the entry to the oral apparatus of the green Trichodina that lives on the surface of a freshwater snail collected in central Illinois. In this view the haplokinety and the polykinety of the ...
