Cardiac muscle cells that are electrically connected by gap junctions and thus the entire myocardium behaves as a single unit.
Network of cardiac muscle cells connected by intercalated discs that lends to the coordinated contraction of the atria
Network of cardiac muscle cells connected by gap junctions that lends to the coordinated contraction of the ventricles
Internal pacemaker and nervelike conduction pathways through the myocardium
Cardiac conduction system
Initiates each heartbeat and determines the heart rate
Acts as an electrical gateway to the ventricles
Type of pathway that signals leave from AV
AV Bundle (Bundle of His)
Also known as the pacemaker of the heart
