Single Unit Visceral Smooth Muscle (SUVSM)

A single smooth muscle cell in a bundle is innervated by an autonomic nerve fibre[[1]]. This cell then propagates an action potential in neighbouring cells due to the presence of many gap junctions[[2]] between the concerned cells. This kind of smooth muscle unit is located in the uterine (for contraction at child-birth), also in the GI tract and the bladder.
