Two of the three types of vesicles that are transported to the cytopharynx and that accumulate in large numbers at the cytopharynx are shown in this electron micrograph. The discoidal vesicles move up...

High resolution image of Halteria showing the extension of buccal cavity and the cytopharynx passing into the cell. Vesicles accumulate at the cytopharynx next to the lamellae. These vesicles may be h...

Cytochalasin B blocks DV release from cytopharynx. In this micrograph a very large nascent vacuole has been retained at the cytopharynx of this cell that had been exposed to cytochalasin B. Many acido...

Detail of the origin of the cytopharyngeal microtubules along the left side of the cytopharynx that arise within the filamentous reticulum in contact with its electron-opaque nodes. This system does n...

Structures at the left edge of the cytopharynx arise in contact with the filamentous reticulum that lies next to the alveoli to the side of the quadrulus. The cytopharyngeal ribbons coming out of the ...

The collapsed cytopharyngeal membrane extends from the open cytopharynx into the cytosol. This membrane is associated with many docked acidosomes, vesicles that contain V-type proton translocating ATP...

Posterior end of the buccal cavity with a nascent phagosome attached to the cytopharynx. The ribbed wall has ended and the cytopharynx is greatly reduced. The quadrulus goes to the end of the buccal c...

Quick-freeze deep-etch rotary-shadowed replica of a portion of the chemically-unfixed cytopharynx. The cytopharynx is continuous with the plasma membrane and is covered by only one membrane which is p...

Section of Halteria showing the extension of buccal cavity and the cytopharynx passing into the cell. Vesicles accumulate at the cytopharynx next to the lamellae. These vesicles may be homologs of dis...
