Quizplus · Accepted Answer

Gap junctions are specialized intercellular connections that allow for direct electrical communication between cells, facilitating the rapid spread of action potentials in cardiac muscle. Fibrous heart rings and electromagnetic discs are not structures involved in electrical signal propagation in the heart. Sarcolemma sclerotic plaques and tight junctions are not relevant to cardiac electrical signal transmission.
