The structure labeled as "C" in the figure likely represents gap junctions, which are specialized intercellular connections that allow for direct communication between cells. Gap junctions enable ions and small molecules to pass freely between cells, allowing entire regions of cells to respond quickly and uniformly to a single stimulus. This is crucial in tissues that require synchronized activity, such as in the heart and in smooth muscle.
