CILIA IN BRONCHUS CILIA IN OVIDUCT FLAGELLA IN SPERM CELLS Microvilli can be found on the exposed surface of the epithelial cells of the small intestine Villi are located inside the inner walls of the small intestine Entamoeba histolytica is an anaerobic parasitic amoebozoan, part of the genus Entamoeba.Predominantly infecting humans and other primates causing amoebiasis DESMOSOMES provide strong adhesion. They connect the intermediate filaments of one cell to those of another, helping tissues withstand mechanical stress, like stretching or pulling. HEMIDESMOSOMES anchor cells to the extracellular matrix, specifically to the basal lamina, which is the layer underneath epithelial cells. Instead of connecting two cells, hemidesmosomes connect the cell to the underlying structure, helping stabilize the tissue Desmosomes: Double connection (between two cells). Hemidesmosomes: Half connection (between a cell and its base). Tight Junctions trap substances, forming a tight seal. Adhering Junctions attach cells, holding them together. Gap Junctions gate communication, allowing cells to share signals. E-source: https://www.slideshare.net/magaoaykevin/lesson-4- cell-modifications
