Cross section the 9 + 2 axoneme of the cilium of Tetrahymena. The plasma membrane covers the axoneme and is continuous with the plasma membrane covering the cell body. Each doublet tilts inward to the...

The flagellar pocket of a Trypanosoma brucei bloodstream form cell, with short flagellum. The image shows a new flagellum starting to grow from the flagellar pocket, in preparation for the next cell d...

Longitudinal section of somatic cilia showing the axoneme, basal body, and attached fibrous and microtubular elements. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alco...

An isolated and longitudinally fractured cilium exposing the middle of the cilium. The spokes extend from the doublets toward the two singlet microtubules. These spokes are spaced unevenly so they app...

High resolution image of an isolated and longitudinally fractured cilium exposing the middle of the cilium. The spokes extend from the doublets toward the two singlet microtubules. These spokes are sp...

High resolution image of longitudinal section of somatic cilia showing the axoneme, basal body, and attached fibrous and microtubular elements. Adjacent digestive vacuoles and cortical cytoplasm evide...

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,...

An image of the transition from basal bodies to cilia within a portion of one of the oral membranelles of Euplotes. Parasomal sacs occur between the rows of basal bodies although these endocytic ports...

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...

A segment of the edge of the axoneme showing the outer axonemal dynein arms that extend from the A-subfiber of a doublet to bind to the B subfiber of the adjacent doublet. TEM taken on 4/21/88 by C. S...
