Excitability - Answer- the ability of non-pacemaker heart cells to respond to an electrical impulse that begins in pacemaker cells. Depolarization - Answer- occurs when the normally negatively charged cells within the heart muscle develop a positive charge. Conductivity - Answer- the ability to send an electrical stimulus from cell membrane to cell membrane. As a result, excitable cells depolarize in rapid succession from cell to cell until all cells have depolarized. Ex: the wave of depol...
