Detailed explanation-1: -Gap junctions play a central role integrating the smooth muscle cell function by coordinating changes in both membrane potential and intracellular Ca2+ between adjacent smooth muscle cells (22–24).
Detailed explanation-2: -Homocellular gap-junctions between smooth muscle in the mesenteric artery enable AP spread without detriment and with no apparent detriment due to myoendothelial gap-junctions.
Detailed explanation-3: -Smooth muscle fibers are often found forming sheets of tissue and function in a coordinated fashion due to the presence of gap junctions between the cells. Termed unitary smooth muscle or visceral muscle, this type of smooth muscle is the most common observed in the human body, forming the walls of hollow organs.
