Cytopharynx in paramecium
WebParamecium, genus of microscopic, single-celled, and free-living protozoans. Most species can be cultivated easily in the laboratory, making them ideal model organisms, well suited for biological study. … WebParamecium contains a reservoir of membrane-forming material in discoid vesicles for the purpose of producing food vacuoles. The food vacuoles form at the cytopharynx when the cytopharyngeal membrane and the discoid vesicles fuse. A close relative of T. brucei, Trypanosoma cruzi, causes Chagas disease, or …

WebThe heterophagic pathway of the digestive lysosomal system in Paramecium caudatum includes at least four steps: digestive vacuole (DV) formation, acidification-condensation, lysosomal fusion-digestion, and defecation. The second and the third require about 20 min, during which DVs are not egested. B … WebA vast neural tracing effort by a team of Janelia scientists has upped the number of fully-traced neurons in the mouse brain by a factor of 10. Researchers can now download and browse the data in three dimensions. These split-GAL4 driver Drosophila lines allow the generation of cell-type specific gene expression.
WebThe morphology of this cytostome-cytopharynx region is described in detail and illustrated with a three-dimensional drawing of a portion of this region and a clay sculpture of the oral apparatus of Paramecium. Evidence from the literature for the transformation of food vacuole membrane into disk-shaped vesicles both from condensing food ... WebThe vesicles, after being transported to the cytostome-cytopharynx region in association with these ribbons, accumulate next to the cytopharynx before they become fused with the cytopharyngeal membrane. This fusion allows the nascent food vacuole to grow and increase its membrane surface area.
