oral apparatus organization
Cellular Component
pellicle
A view of cross sections of the finger-like extensions of the alveoli that bind to the cytostomal cord. Alveoli store calcium (see Stelly et al., J. Cell Biol. 113:103-112, 1991) and calcium release c...

Paramecium caudatum
Biological Process
oral apparatus organization
Cellular Component
oral apparatus
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...

pre-autophagosomal structure membrane
The nascent phagosome membrane has a dense coat of acidosomes docked at its cytosolic surface well before the nascent vacuole pinches off the cytopharynx. This micrograph is a quick-freeze deep-etch i...

Didinium nasutum
Biological Process
phagocytosis
Cellular Component
oral apparatus
The ingestion of Paramecium by Didinium. This micrograph also clearly shows the five short rows of clavate cilia (ciliary stubs without central microtubules) that reside just below the anterior and po...

Didinium nasutum
Biological Process
phagocytosis
Cellular Component
oral apparatus
Didinium captures Paramecium. Also showing metachronous waves of cilia in the two characteristic ciliary girdles of Didinium nasutum. This micrograph was taken in 1968 by G. Antipa on a Cambridge Mar...

Paramecium multimicronucleatum
Biological Process
oral apparatus organization
Cellular Component
oral apparatus
The buccal cavity opens into the developing digestive (food) vacuole at the terminal edges of the alveolar sacs that cover the buccal cavity. A plane connecting these edges would roughly describe a te...

Paramecium multimicronucleatum
Biological Process
oral apparatus organization
Cellular Component
oral apparatus
The cytopharynx in cross section showing the cytopharyngeal microtubular ribbons lying in the plane of the section. Some discoidal vesicles, some containing HRP label, are also seen in planar view. Ac...

Paramecium multimicronucleatum
Biological Process
oral apparatus organization
Cellular Component
oral apparatus
One important function of the filamentous reticulum is to provide for the anchorage of cytopharyngeal microtubular ribbons along the left lip of the cytopharynx. This micrograph shows two ribbons aris...

oral apparatus
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...
