Cardiac muscle group fabric are comprised of multiple skin cells interconnected in selection and parallel with one another. At each intercalated disc the mobile phone membranes fuse with the other person to create space junctions which allow accelerated diffusion of ions. So, from your purposeful point of view ions transfer the intracellular solution on the cardiac muscle mass fibres to ensure that motions potentials commute readily from just one cardiac muscles to the next, past the intercalated discs.
