And this type of arrangement of cardiac muscle cells in the heart basically allows for a uniform and synchronized contraction of our heart. So if we take a look at the following diagram, this is cardiac muscle cell number one, cardiac muscle cell number two. This separating region that connects them is the intercollated discs and it contains one type of junction known as a gap junction, that allows for a rapid communication between cells. And it also contains a second type of intracellular junction known as the desmosome. And the desmosome is basically the intracellular junction that actually glues the two cells together, that holds the two cells together and allows them to stick together when we have that contraction actually taking place. So this is the second important difference between cardiac muscle cells and skeletal muscle cells.
