Action potential Correct Answer: The process by which excitable cells transmit information from one to another. 
 
How is the action potential altered by a potassium imbalance? (Hyperkalemia) Correct Answer: The ECF has more K+ ions. The membrane potential becomes more positive (hypopolarized). 
Cells become MORE excitable.

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 depolarizat...
