High resolution micrograph showing an overview of the peristome of Opercularia coarctata. The corrugated wall, the equivalent to the ribbed wall of Paramecium, contains tubular projections of alveoli ...

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 micrograph may show important features involved in calcareous plate formation within the alveoli that underlie the plasma membrane in Coleps. Densities are seen on the inner alveolar membrane at ...

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 high resolution micrograph of the proximal ends of the basal bodies of a cirrus of Euplotes. the basal bodies are embedded in a perforated plate of electron opaque material. Microtubules arise from ...

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 myoneme of Opercularia coarctata. Such fibrous bundles are known to be composed of centrin, a filament that contracts when exposed to calcium. The ER is closely associated with the myonemes and send...

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...

Figure 322 from Chapter 13 (Cilia and Flagella) of 'The Cell' by Don W. Fawcett M.D. Cilia and flagella usually occur on motile cells or on the free surfaces of epithelia. However, a solitary cilium i...
