Which type of epithelial junction plays a role in an epithelial sheet’s ability to develop tension or change its shape by contraction?
|
|
Desmosome
|
|
|
Gap junction
|
|
|
Tight junction
|
|
|
Adherens junction
|
Explanation:
Detailed explanation-1: -Tight junctions form the continuous intercellular barrier between epithelial cells, which is required to separate tissue spaces and regulate selective movement of solutes across the epithelium.
Detailed explanation-2: -Cytokeratins bind to desmosomes at cell–cell contacts and hemidesmosomes at cell–ECM contacts. Together, these junctions and the cytokeratin network ensure tissue integrity and provide tissue elasticity, allowing epithelia to bend and stretch.
