In this way, gap junctions provide metabolic and electrical coupling between cells. For example, cardiac tissue has extensive gap junctions, and the rapid movement of ions through these junctions ...

Gap junctions facilitate the exchange of solutes, metabolic precursors and electrical currents between neighbouring cells. They appear as clusters (or plaques) of tightly packed particles ...

1 Neurons are composed of a cell body containing the nucleus, dendrites that receive chemical, electrical, or other signals via receptors or through gap junctions (direct connections between two ...
