So we have a single neuron, the axon. The axon splits into these two sections, these two groups. And only one of these cells, this cell here and this cell here, is actually innervated by that neuron. All the other cells, this cell, this cell and this cell and these other cells are not actually connected to our neuron directly. So in our single unit smooth muscle, what we have are gap junctions. So all these different types of cells that are connected are connected via these intracellular connections known as gap junctions.
