CIL:36712
NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
microtubule cytoskeleton organization
Cellular Component
microtubule associated complex
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...

NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
microtubule cytoskeleton organization
Cellular Component
oral apparatus
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...

NCBI Organism Classification
Paramecium caudatum
Biological Process
oral apparatus organization
Cellular Component
oral apparatus
Cross section of the oral region (buccal cavity) posterior to the vestibulum. The cytopharynx is beginning on the dorsal surface and the ribbed wall, peniculi and quadrulus are present on the right an...

Paramecium multimicronucleatum
Biological Process
oral apparatus organization
Cellular Component
oral apparatus
The oral region, illustrated here in a freeze-fracture image that passed through its left side, opens at the mid-ventral part of the cell. It consists of a funnel shaped vestibulum covered with regula...

Didinium nasutum
Biological Process
phagocytosis
Cellular Component
oral apparatus
Didinium captures Paramecium. Paramecium is almost completely ingested and the proboscis is beginning to reform. This micrograph was taken in 1968 by G. Antipa on a Cambridge Mark IIA operating at 20k...

NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
oral apparatus organization
Cellular Component
oral apparatus
The postoral microtubular bundles form a track along which a newly released food vacuole rapidly migrates to the cell’s posterior end. Here the flattened cytopharyngeal membrane lies next to these b...

Paramecium multimicronucleatum
Biological Process
oral apparatus organization
Cellular Component
oral apparatus
The finger-like alveolar extension in longitudinal view lies along the dorsal surface of the filamentous reticulum from which the cytopharyngeal microtubular ribbons originate. Whiskers of electron de...
