Why are adhering junctions common in tissues subject to constant abrasion or stretching such as skin?

Adhering junctions, or desmosomes, are common in tissues like skin that experience constant abrasion or stretching because they provide strong mechanical stability and resistance to tensile forces. These junctions connect adjacent cells through protein complexes that anchor to the cytoskeleton, allowing cells to withstand stress and maintain structural integrity. This durability is crucial for protecting underlying tissues and ensuring the overall function of the skin as a barrier. Additionally, their presence helps in maintaining tissue cohesion during movements and external forces.
