The cytopharyngeal ribbons of microtubules tend to curve into a “C” shape away from the cytopharynx but they still remain connected as a ribbon and are heavily labeled by immunogold when exposed t...

High resolution detail of cytopharyngeal vesicles. TEM taken on 3/2/71 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 19,500X. The raw film was scanned with an Epson Perfection V750 Pro. This ...

The postoral fibers are also heavily labeled by anti-b-tubulin. The cell was lightly fixed, placed in metylcellulose and frozen in liquid nitrogen. Sections were produced at -100°C before thawing and...

Figure 301 from Chapter 12 (Centrioles) of 'The Cell' by Don W. Fawcett M.D. Centrioles are usually positioned so that their long axes form a right angle. Their perpendicular orientation is maintained...

An image of the base of a dikinetid deeper in the cell. A postciliary ribbon and other microtubules fan out from it's basal bodies. TEM taken on 6/3/69 by R. Allen with Philips 300 operating at 60kV. ...

Transmission electron micrograph of section through the macronucleus of Nassula sp containing many darkly staining nucleoli.

High resolution image of the somatic basal bodies along the sides of the cytoproct ridge have bundles of microtubules extending into the endoplasm from near their proximal ends. These bundles make con...

At this level of the buccal cavity the opening into the cytopharynx is not seen. Pharyngeal vesicles accumulate at the ends of the cytopharyngeal lamellae and are present under the basal bodies of the...

The somatic basal bodies along the sides of the cytoproct ridge have bundles of microtubules extending into the endoplasm from near their proximal ends. These bundles make contact with the spent vacuo...

The contractile vacuole and cortex of Didinium nasutum showing an extrusive organelle (cyrtocyst) of unknown function. Further details available at Wessenberg, H. and Antipa, G. 1968. Studies on Didin...
