Kinetodesmal fibers arise from the proximal ends of the basal bodies and curve upward and to the cell’s right of the kinety. Together with kds arising from more posterior basal bodies they form a st...

The scopula, stalk-forming region, is outlined by a circle of basal bodies that produce short modified cilia. Other basal bodies lie within this circle. The sheath is secreted outside the circle of ci...

Tangential section through the anterior half of the cytopharyngeal basket. Drawings and discussion of the basket can be found in a paper by Tucker, J. Cell Science 3: 493-514, 1968. TEM taken on 4/1/6...

A high magnification view of the paracrystalline structure of the trichocyst tip and the cortex and core of the resting trichocyst body. Details of the sheath around the tip spike are also shown. (For...

Detail of the filamentous reticulum along the left side of the cytopharynx from which cytopharyngeal ribbons arise next to its nodes. Quadrulus associated ribbons lie between the filamentous reticulum...

This section is cut at a level where the macronucleus is folded so it appears to be in 2 parts and where the micronucleus is visible. Contractile vacuole, perioral kinetids, and the peristome is evide...

Nucleoli in a macronucleus of a cell undergoing micronuclear division. The nucleolus appears to have an organized surface layer composed of parallel threads of subunits. These may be developing riboso...

The macronucleus, one micronucleus, and the cytoplasm of Conchophthirus. The negative magnification is 6,800X. The raw film was scanned with an Epson Perfection V750 Pro. This image is best used for q...

Cross sections of striated bands and infraciliary lattice arms. Filaments of the striated bands are less densely packed than the infraciliary lattice. Kinetodesmal fibers and postciliary microtubules ...

The deep fiber is associated with the cytopharyngeal membrane (see Smith and Bunse, Trans. Am. Microsc. Soc. 102:264-271, 1983). This membrane has acidosome-like vesicles docked at its cytosolic surfa...
