Action Potentials Explored Contents

  • Introduction: Sensing Pain
  • Section 1. Neurons Communicate
    Neurons rapidly transmit information over long distances in a series of electrical pulses called action potentials.
  • Section 2. Ion Movement
    The action potential is generated by the movement of sodium and potassium ions across the cell membrane through voltage-gated ion channels.
  • Section 3. Action Potentials Challenge
    An experimental section for further exploration of action potentials.
  • Section 4. Graded Questions
