Modified basal bodies, composed of a circle of 9 single microtubules, occur along the length of the stalk and these basal bodies lie against the alveolar-bearing side of the stalk. Fibers pass into th...

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...

The locomotor cortex of Didinium. A longitudinal section of basal bodies and the axonemes of cilia is revealed as they emerge from the cell cortex of Didinium. Bundles of microtubules extend from the ...

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 cross section showing only one basal body in two different dikinetids. Cross sections of overlapping microtubular ribbons arising from the dikinetids are seen in the ridges next to the basal body. P...

High resolution image of the surface pattern of P. tetraurelia in a region with two basal bodies in each cortical unit. This is a thin-frozen section labeled with immunogold showing the location of b-...

The proximal end of the basal body is sometimes the origin of other single microtubules or bundles of microtubules that extend deeper into the cell’s endoplasm. These guide trichocysts, tip first, t...

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 ...
