Cardiac Tissue

Cardiac Tissue

  • Made up of protein filaments.
  • Make up wall of heart
  • Cells only contain 1 nucleus
  • Cells are held together by gap junctions and intercalated disks which allow for quick impulses to quickly spread through the tissue

You can see the disks and gaps clearly in a microscopic picture of the tissue

At the cellular level, the main components of the postnatal heart are cardiomyocytes, cardiac fibroblasts, endothelial cells and vascular smooth muscle cells (Banerjee I, fusel JW, 2007). In a normal adult heart, cardiomyocytes occupy most of the tissue volume, but they are only 30% of the total number of cells. The remaining 70% consists of non-cardiomyocyte cell types, among which cardiac fibroblasts represent the vast majority (Jugdutt, 2003).
