    Functional syncytium
  2. Network of cardiac muscle cells connected by intercalated discs that lends to the coordinated contraction of the atria
    Atrial syncytium
  3. Network of cardiac muscle cells connected by gap junctions that lends to the coordinated contraction of the ventricles
    Ventricular syncytium
  4. Internal pacemaker and nervelike conduction pathways through the myocardium
    Cardiac conduction system
  5. Initiates each heartbeat and determines the heart rate
    SA Node
  6. Acts as an electrical gateway to the ventricles
    Atrioventricular Node
  7. Type of pathway that signals leave from AV
    AV Bundle (Bundle of His)
  8. Also known as the pacemaker of the heart
