Dead skin cells are shed in sheets because they are held together by strong intercellular connections that resist mechanical stress named

A. gap junctions

B. desmosomes

C. tight junctions

D. intermediate junctions

Solution

b.desmosomes

Dead skin cells are shed in thin sheets because they are held together by spots of proteoglycans reinforced by intermediate filaments.Such strong intercellular connections are called as desmosomes.Desmosomes are intercellular junctions that provide strong adhesion between cells. Because they also link intracellularly to the intermediate filament cytoskeleton they form the adhesive bonds in a network that gives mechanical strength to tissues.

Tight junctions prevent the passage of water and solutes between cells.
In gap junctions,two cells are held together by two interlocking transmember proteins called connexons,they only let small molecules and ions pass from cell to cell.
