High resolution view of the bundles of microtubules that arise from along the elaborately woven blanket of the filamentous reticulum that covers the ribbed wall of the right side of the buccal cavity....

Immunogold labeled microtubules next to the cytoproct radiate from basal bodies and also from the tip of the cytoproct. These microtubules lie along the approaching spent DV. b-tubulin immunogold labe...

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...

High resolution view of the quadrulus membranelle (4 rows of cilia) in the buccal cavity of Paramecium tetraurelia labelled for tubulin. Microtubules of the axonemes of the cilia and the triplet fiber...

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-tubulin. The gold lies over t...
