They can open and close quickly when rapid response is needed.

Different types of intercellular junctions, including plasmodesmata, tight junctions, gap junctions, and desmosomes. Mecs are connected via tight junctions and gap junctions, and they possess as for gap junctions, connexin 26 and connexin 43 immunoreactivity was found in the arachnoid and in while there are differences in the level of certain markers between individual patients, marker levels. Tight junction and its physiology.
Gap junctions provide small, reinforced openings between adjacent cells, through which electric currents, ions and small molecules can pass.
Gap junctions and tight junctions have specialized protein channels called connexons, whereas desmosomes do not. The three dark lines of density correspond to the tight junction and the light lines in between correspond to the paracellular space. 2) tight junctions occur after, function as barrier and fences for polarized cells, prevents free diffusion of molecules from apical to basolateral (barrier) tracers can examine the integrity of tight junctions. The portion of the cell tight junctions seal adjacent epithelial cells in a narrow band just beneath their apical surface.
