Cell To Cell Interactions Flashcards
What is the primary function of tight junctions in epithelial cells?
Seal spaces between cells to prevent leakage
Which junction type is primarily involved in direct communication between neighbouring cells?
Gap junctions
How do microvilli on the apical surface of intestinal epithelial cells assist their function?>
By increasing surface area for nutrient absorption
What structure connects epithelial cells to the basal lamina?
Hemidesmosomes
What could happen if desmosomes are defective in epithelial tissue?
Weak mechanical resistance to stress
Which statement about adherens junctions is correct?
They create a continuous belt around cells to brace and control their shape
What is the primary role of tight junctions in the small intestine?
Control the movement of substances between the intestinal lumen and the bloodstream
