Polykinetids of one membranelle of the buccal cavity, probably membranelle 1. Accessory microtubules arise from the row of basal bodies on one side. Parasomal sacs are not seen associated with this me...

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...

Basal body formation occurs most prominently in the equatorial region of the predivision cell. A new basal body begins to develop perpendicular to the mature basal body at its proximal anterior surfac...

A high resolution image of the detail of cell surface structures. The cell is covered by the plasma membrane and outer alveolar sac membrane which is separated from the inner alveolar sac membrane by ...

High resolution image of the detail of the three fibers supporting a basal body. A striated kinetodesmal fiber extends anteriorly from the basal body, a postciliary microtubular ribbon extends posteri...

A high resolution image of an individual cirrus of Euplotes with 91 cilia/basal body complexes. The transition from basal body to cilium can be followed from right to left in each row. Small vesicles,...

The proximal ends of the basal bodies of a cirrus are embedded in a perforated plate of electron opaque material. Microtubules arise from this opaque material. A secondary fretwork of connections bind...

An image of the microtubular nemadesmata that extend deep into the cytosol from the membranelles of the perioral kinetids. Bridges link the plasma membrane to the alveoli. Parasomal sacs occur around ...

A view of the AZM with basal bodies in longitudinal section and cilia sectioned lengthwise. Bunches of microtubules reside below the basal bodies and lie close to the cytopharyngeal vesicles. TEM take...

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, and to transverse microtubu...
