KCl Injection mechanism?

  1. Sep 27, 2006 #1
    Ok so I know with the injection of potassium chloride, the potassium in the extracellular fluid works to inhibit any repolarization, by increasing the amount of K in the extracellular fluid (hence not allowing EPSPs to reach threshold and trigger Na channels for an action potential), however, wouldnt the Chlorine have the opposite effect of the potassium since its negatively charged? Its a negatively charged ion, thus cancelling out the polarity that the K makes...???

    Whats the role of chlorine?? UNLESS...it forms a gas and just diffuses out everywhere?
