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...

High resolution 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 t...

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...

High resolution image of cilia and cytopharyngeal vesicles containing a flocculent content of unknown composition which lie next to the cytopharynx and between the buccal cavity and what may be the n...

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...

Scanning electron microscope image of Strongylocentrotus drobachiensus [sea urchin] at the gastrula stage. Embryo was cut in half to reveal blastocoel cavity, containing blastocoel matrix material, pr...
