  1. Mass of merging cells that act as a unit
    Functional Syncytium
  2. Network of cardiac muscle cells connected by disc that leads to the coordination contraction of the atria
    Atrial Syncytium
  3. Network of cardiac muscle cells connected by junctions that leads to the coordination contraction of the ventricles
    Ventricular Syncytium
  4. Coordinates events of the cardiac cycle
    Cardiac Conduction System
  5. Small, elongated mass beneath epicardium. In right atrium near opening of superior vena cava. Fibers are continuous of atrial syncytium
    Sino Atrial (SA) Node
  6. in the inferior portion of septum and just beneath the endocardium. Provides normal conductions pathway between atrial and ventricular syncytium.
    Atriventricular (AV) Node
  7. Enters upper part of inerventricular septum and divide into right and left bundle branches that lie just beneath the endocardium.
    AV Bundle (Bundle of HIS)
  8. Generates hearts rhythmic contractions.
    Pacemaker
  9. Larger fibers carry impulses to distant regions of the ventricular myocardium much faster than cell to cell conduction could.
    Purkinje Fibers
