Quizplus · Accepted Answer

The intercalated disks are thickened portions of the sarcolemma and enable electrical impulses to spread quickly in a continuous cell-to-cell (syncytial) fashion. A sarcolemma is a transparent sheath that surrounds nerve fibers. They are not subject to plaque buildup. The trabeculae carneae are beam-like projections of myocardial tissue. Bachmann bundles are part of the conduction system.
