Source sentences:
text: pacemaker cells pacemaker cells in the sinoatrial node are responsible for generating action potentials that will ultimately cause heart to beat (single heartbeat corresponds to initiation and conduction of single action potential) - sinoatrial node generates spontaneous action potentials because it has lots of pacemaker cells (action potentials will then propagate throughout electric conduction system within the heart, and can do so because of gap junctions connecting subsequent cells within the conduction system)
