A tangential view through a dikinetid shows two microtubular ribbons extending toward the pellicle, one from each basal body, and how they overlap with ribbons from other basal bodies under the pellic...

Longitudinal section through the buccal cavity of the oral region showing portions of 3 membranelles (1, 2 and 3): each membranelle consists of 3 rows of cilia. The oral ribs are seen on the right sid...

Paramecium caudatum is a peniculine oligohymenophoran ciliate that has numerous rows of cilia called kineties that run along the posterior to the anterior axis on the cell’s dorsal side but curve ar...

A grazing section through the cell’s surface shows segments of six rows of cilia running across the figure sectioned superfically at the top and deeper into the cell as one progresses down the figur...

A grazing section through the dorsal surface of Euplotes showing cross sections of cilia in four of the sparsely ciliated kineties . A layer of mitochondria underlies the pellicle. A replication band ...

Cirri arise from the ventral side and the adoral zone of membranelles circle the anterior end of the cell and curve ventrally along one side of the oral cavity. The AZM is composed of triplet rows of ...

Cross section of a cilium showing the 9 + 2 axoneme. Two dynein arms, inner and outer, of heterogeneous appearance arise from the complete microtubule of each doublet. Spokes extend from the doublets ...
