multiple choice question\nan extracellular junction that forms an impermeable barrier is called a(n)\ntight junction\ngap junction\nadhesion junction

Answer

Brief Explanations:

Tight junctions seal adjacent epithelial cells in a narrow band just beneath their apical surface. They limit the passage of molecules and ions through the space between cells, forming an impermeable barrier. Gap junctions allow for the direct passage of small molecules and electrical signals between cells, and adhesion junctions mainly function in cell - cell adhesion and maintaining tissue integrity, not in forming impermeable barriers.

Answer:

tight junction
