The cells of all tissues are coupled by gap junctions, with the exception of blood and adult skeletal muscle cells. Gap junctions provide for homoeostasis and integrative function by mediating the exchange of ions and chemical second messenger molecules between adjacent cells. The electrical signaling provided by these specialized intercellular junctions is perhaps best understood in the heart, where their abundance serves to provide low electrical resistance pathways for current flow – ensuring fast and efficient transfer of
