This EM features the infraciliary lattice which forms a continuous network at the level of the proximal ends of basal bodies where the kinetodesmal fibers are connected to the posterior basal bodies o...

11 micrographs of views of a serially-sectioned contracted Vorticella convallaria cell that show the main features of this cell. This figure shows 5 food vacuoles and the edges of 2 more. The connecti...

The contractile vacuole pore is supported on its cytosolic side by a coil of microtubules and other microtubules extend from the pore to the CV membrane. The plasma membrane and CV membrane cover the ...

Vorticella convallaria has a contractile stalk that arises from the aboral pole of the cell. The myonemes from the body converge at this pole and pass into the stalk to form a large contractile bundle...

Ciliates such as Paramecium have specialized sites for endocytosis and exocytosis. Most of their surface is not available for internalization of membrane because of the underlying alveolar sac system....

Sections show the origin of one cytopharyngeal ribbon of 12 microtubules from the nodes and show the tight curve the ribbon follows over the cytostomal cord. These ribbons move discoidal vesicles, aci...

Opercularia coarctata. Transmission electron micrograph of contracted cell body. This ciliate does not have rows of basal body/cilia over its whole surface but has cilia in the oral region and in a tr...

Computed slice through a tomographic reconstruction of the pre- and post-synaptic structures of the calycal synapse onto a chick ciliary ganglion neuron. This slice was derived from the 3rd of 6 seri...

The nascent digestive vacuole forms as the membrane of flattened vesicles fuse with the single membrane of the cytopharynx between the lamellae (2 microtubules forming a lamella) that are connected al...

TEM image of frozen hydrated soluble chromatin isolated from COS-7 cells and vitrified in 15 mM monovalent ions. The chromatin adopts an irregular zigzag fiber conformation. See Fig 2 in J Bednar et ...
