Intercalated discs or lines of Eberth are microscopic identifying features of cardiac muscle. Cardiac muscle consists of individual heart muscle cells (cardiomyocytes) connected by intercalated discs to work as a single functional syncytium. By contrast, skeletal muscle consists of multinucleated muscle fibers and exhibits no intercalated discs. Intercalated discs support synchronized co… WebJun 15, 2024 · Intercalated discs Function/Purpose The primary role of the cross-bands is to hold the adjacent cells together by providing sites of strong adhesion. The gap junctions promote diffusion of ions between cells and allow waves of depolarization to spread over the entire heart by passing from cell to cell. clean air with essential oils
