Vestibular kinities and the cortical architecture adjacent to the oral apparatus of Conchophthirus curtus. The negative magnification is 15,500X. The raw film was scanned with an Epson Perfection V750...

This micrograph shows that the discoidal vesicles meet the cytopharyngeal membrane edge-on where they fuse. Besides the ribbon of 12 microtubules abutting the membrane there is a second small ribbon o...

A glancing view of the cortex of Conchophthirus reveals details of cortical structure. This includes the nature of the cell membrane and the alveolar membranes that reside immediately below the surfac...

An image of the cortex of Tetrahymena showing a longitudinal microtubular ribbon sandwiched between the alveoli and the epiplasm in the crest of the pellicular ridge. A parasomal sac, the distal end o...

High resolution image showing that one parasomal sac lies anterior to each basal body of the somatic ciliature. A parasomal sac is an indentation of the plasma membrane that penetrates into the cytoso...

Receptor mediated endocytosis is a process in which extracellular molecules are taken into the cell via coated vesicles that pinch from the plasma membrane. In Paramecium the resulting vesicles fuse w...

A glancing view of the cortex of Conchophthirus reveals details of cortical structure. A near serial section with CIL:39239. This includes the nature of the cell membrane and the alveolar membranes th...

A transverse section of the cortex of Conchophthirus curtus reveals details of cortical structure. This includes the nature of the cell membrane and the alveolar membranes that reside immediately belo...

Conchophthirus was deciliated by calcium ion shock followed by shearing through a micropipette. This revealed the location of the deciliated basal bodies and the cell's surface architecture. In this i...
