Paramecium multimicronucleatum
Biological Process
oral apparatus organization
Cellular Component
plasma membrane
The E-fracture faces of the plasma membrane and cytopharyngeal membranes are continuous but differ in appearance since the cytopharyngeal membrane is studded with IMPs while the plasma membrane has fe...

oral apparatus
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...

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 tetraurelia
Biological Process
microtubule cytoskeleton organization
Cellular Component
cell cortex
Quadrulus membranelle (4 rows of cilia) in the buccal cavity of Paramecium tetraurelia. Microtubules of the axonemes of the cilia and the triplet fibers of the basal bodies are labeled. Ribbons of mic...

Cellular Component
pre-autophagosomal structure
One segment of the assembly line used for phagosome membrane growth in P. caudatum. Cytopharyngeal ribbons bring discoidal vesicles to the left lip of the cytopharynx where the vesicles bind and then ...

early phagosome
Immunogold label specific for Q2 antigen on discoidal vesicles. The same mAb used in CIL:36721 heavily labels discoidal vesicles and less heavily the cytopharyngeal membrane. A few gold particles are ...
