The correct answer is 'B', Gap junctions.

Изложение

## Step 1<br />The question is asking about the type of junction that allows electrical coupling between adjacent cells in visceral smooth muscle. <br /><br />## Step 2<br />Electrical coupling between cells is a process where the electrical activity of one cell is transmitted to another cell. This is crucial for the coordinated contraction of smooth muscle tissues.<br /><br />## Step 3<br />Among the options provided, gap junctions are the structures that allow for this type of electrical coupling. They are specialized intercellular connections that facilitate the direct exchange of ions and small molecules between the cytoplasm of adjacent cells.<br /><br />## Step 4<br />This exchange of ions and small molecules allows for the rapid spread of electrical impulses across the muscle tissue, leading to coordinated contraction.<br /><br />## Step 5<br />The other options, such as dense bodies, intermediate fibers, mechanical junctions, and potassium channels, do not play a direct role in electrical coupling between cells.
