A high resolution image of a longitudinal section of an oral basal body and cilium with the attachment of a bundle of microtubular filaments and a rod that covers the proximal end of the basal body. A...

Overview of Coleps hirtus cell seen in this median transverse section. This barrel-shaped cell has a few rows of cilia and the cell is covered with calcified polysaccharide platelets that are housed w...

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 ...

The aboral view of Didinium showing seven contractile vacuole pores for it's single posterior contractile vacuole and metachronous waves of cilia in one of the two characteristic ciliary girdles of Di...

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 ...

The highest concentration of parasomal sacs is found in the oral region associated with the three ciliary membranelles, called in Paramecium, the ventral amd dorsal peniculi and the quadrulus. This mi...

A high resolution view of cross-sectioned rows of basal bodies at the cortex of Nassula. Only a few basal bodies may have attached cilia as seen by the few cilia present in the upper right row. Basal ...

Cross section of a Coleps cilium showing the axoneme consisting of 9 doublet and 2 central microtubules. Doublets have a complete A subfiber and an attached B subfiber. Two dynein arms, outer and inne...

The monokinetids (single somatic basal bodies) of Coleps hirtus bear an anteriorly directed striated fibrous kinetodesmal fiber and a posteriorly directed ribbon of postciliary microtubules that arise...
