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...

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 Nassula sp. showing rows of cross-sectioned basal bodies at the cell surface. TEM taken on 3/4/69 by R. Allen with Philips 300 operating at 60kV. Neg. 16,000X. The raw film wa...

A high resolution image of a cortical monokinetid showing the basal body as well as postciliary and transverse microtubular ribbons. Slender endosomal vesicles accumulate near the bottom of a parasoma...

Surface of Coleps hirtus. Alveoli have longitudinal margins along the ciliary rows as well as lateral margins spaced at intervals of one or two basal bodies along the rows. Margins of adjacent alveoli...

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 posteriorly and a transverse mic...

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 an extensive alveolar space. Ci...

Scanning electron microscope image of Strongylocentrotus drobachiensus [sea urchin] at the gastrula stage. Embryo was split open to reveal a nice cross-section through the outer epithelial layer and t...
