High resolution image of a tangential section of basal body pair (dikinetid) showing a connecting fiber linking the BBs as well as attachments to a kinetodesmal fiber, to postciliary microtubules, an...

The oral apparatus of Tetrahymena. 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 h...

Cross sections of a pair of basal bodies showing the triplet makeup of the 9 fibers; only one microtubular fiber is complete in each triplet while the other two microtubular fibers share some subunits...

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...

High resolution image of microtubules that sometimes extend deep into the cytosol from the basal bodies. They serve to guide the trichocysts to their docking sites at the plasma membrane (see Plattner...

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...

A glancing view of the thigmotactic ciliature of Conchophthirus reveals details of cortical structure. CIL:39231 is a near serial section. Both exhibit the characteristic zig-zag kinetal arrangement o...

High resolution image of cross sections of basal bodies at the level of their attachments to the kinetodesmal fiber, the anterior basal body is attached by a thin bridge. The proximal ends of one post...

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...

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 ...
