Quiz: Depolarization and polarization — cellular action potential

Take this quiz to test your knowledge of sodium, potassium and calcium cellular action potentials


The concept of airway, breathing and circulation have been stalwart concepts since the inception of EMS training. Although these concepts are important, it is difficult, if not impossible to understand how these systems truly function without addressing what is happening at the cellular level of physiology. In certain aspects, possessing a foundational understanding of cellular action potentials is more important than the ABCs themselves.

Read “Let’s get cellular: Teaching cellular action potential with the schoolhouse theory,” and take this quiz to test your knowledge.

EMS students can have a difficult time contextualizing information. Learn how to conduct a pluck lab to teach anatomy, physiology and pathophysiology in a dynamic way with Kelly Grayson’s article, “Moist organs and kinesthetic learners.”
