So basically, as soon as the action potential is received by this cell, shown in red, is then split to the other cells and the same thing happens in this particular case. So this red arrow basically describes the movement of our action potential. So this sort of arrangement allows the group of smooth muscles to contract as a single unit as a whole.

And these types of arrangements are found in places like the uterus in our stomach, in the small intestine, as well as in small arteries and veins. So now let's move on to the second type of arrangement known as the multiunit smooth muscle.
