Which of the following describes desmosome function?
|
|
Forms a tight seal between cells preventing the movement of materials
|
|
|
links cells together but allows materials to move between cells
|
|
|
links cells together but lets adjacent cells communicate
|
|
|
None of the above

Explanation:
Detailed explanation-1: -Desmosomes represent major intercellular adhesive junctions at basolateral membranes of epithelial cells and in other tissues. They mediate direct cell-cell contacts and provide anchorage sites for intermediate filaments important for the maintenance of tissue architecture.
Detailed explanation-2: -Much like tight junctions, desmosomes physically hold the cells together, but do not allow fluids or materials to pass from the inside of one cell to the next.
Detailed explanation-3: -Adherens junctions and desmosomes hold cells together and are formed by transmembrane adhesion proteins that belong to the cadherin family.
