epithelium that is lining the organs that are subjected to stress or sometimes that can stretch are expected to have numerous a)desmosomes b)gap junctions c)tight junctions d)basement junctions

Answer 1

Answer:

Epithelium that is lining the organs that are subjected to stress or sometimes that can stretch are expected to have numerous desmosomes.

Explanation:

Desmosomes are highly ordered and specialized membrane domains that facilitate cell-cell interaction and strong adhesion. The adhesive interaction is coupled to the cytoskeleton. By doing cell-cell adhesion and cytoskeletal linkages, they mechanically integrate cells within tissues and hence resist mechanical stress.

Gap junctions, tight junctions, anchoring junctions are the two basic types of cell to cell junctions. Gap junction facilitates the movement of small molecules and ions across the cells by forming an intercellular passageway between the membranes of the adjacent cells. Tight junction forms a firm seal due to the presence of fused integral proteins that restricts the movement of fluids across the adjacent cells. Hemidesmosomes are found on basal membranes.  

Answer 2

Epithelium that is lining the organs that are subjected to stress or sometimes that can stretch is expected to have numerous (A) desmosomes.

• Desmosome is a specialized cell membrane structure, especially in epithelial cells, that acts as an adhesion zone to hold adjacent cells together.
• A type of intercellular junction structure that works as an adhesion zone to keep neighboring cells together, especially in epithelial cells.
• Desmosomes are capable of withstanding mechanical stress because they possess the hyper adhesive property and inner signaling between their cells.
