| 11. | Inside the pacemaker cell, where the positively-charged sodium ions leak in, the electrical charge gets more positive.
|
| 12. | The pace for blood pumping, are called "'pacemaker cells "', and they directly control the heart rate.
|
| 13. | The pacemaker cells make up 1 % of cells and form the conduction system of the heart.
|
| 14. | Even if it stops the heart it may restart, thanks to the pacemaker cells Cardiac action potential.
|
| 15. | This transgene is widely expressed among pacemakers and also found in a limited number of non pacemaker cells.
|
| 16. | The cardiac action potential is created by the movement of specific electrolytes into and out of the pacemaker cells.
|
| 17. | Gap junctions allow the spontaneous depolarization and action potential generated by pacemaker cells to be transferred to contractile cells.
|
| 18. | Some slow firing by pacemaker cells and weaken heart contractions; others reduce blood pressure by dilating narrowed blood vessels.
|
| 19. | Cardiac pacemaker cells ( autorhythmic cells ) are connected to adjoining contractile cells ( non-pacemaker cells ) via gap junctions.
|
| 20. | Being myogenic, the heart's pace is maintained by pacemaker cells found in the sinoatrial node, located on the right atrium.
