Action Quizzes & Trivia

Polarization is the property applying to transverse waves that specify the geometrical orientation of the oscillations. Phases of action potential gauge your understanding of the different aspects of polarization. Take up the challenge and all the best.

Questions and Answers
  • 1. 
    Rapid Depolarization  - sodium(Na) ions flooding into the cell
  • 2. 
    Early Repolarization -  The influx of sodium slows and the cell begins to repolarize.
  • 3. 
    Plateau Phase (Repolarization)  -  Slow inward movement of calcium and outward movement of potassium
  • 4. 
    Rapid Repolarization -  the end of sodium and calcium inflow and the rapid outward of potassium
  • 5. 
    Absolute Refractory Period n-
  • 6. 
    Relative Refractory Period - the cell can be excited to produce an action potential but only by a stimulus that is much stronger than normal
  • 7. 
    Resting membrane potential - large permeable to potassium with the net loss of intracellular potassium
