Now the multiunit smooth muscle is a less common type of arrangement of our smooth muscle. So basically in this case, every single smooth muscle cell in this multi unit section is innervated by a neuron. So we have each and every one of these smooth muscle cells is connected to some type of axon terminal of a neuron. So we have these two neurons and each one of these cells are basically connected. So what this basically means is if an action potential spreads to this axon and causes these three smooth muscle cells to contract, that does not mean that these neighboring cells, these cells will also contract. So that means the contraction of these smooth muscles is independent of the contraction of these neighboring smooth muscles.
