  • Resting membrane potential means that the inside of the membrane is negative in relation to the outside of the membrane
  • Depolarization the inside of the membrane becomes less negative and approaches zero
  • Hyperpolarization the inside of the membrane becomes more negative and comes further from zero in negative values
  • Excitable cells neurons, muscle fibers and some others have the ability to generate electrical signals
  • Voltage clamp an electronic device that allows the experimenter to measure whole –cell ionic current, by setting the membrane potential very quickly to a predetermined value
  • Nonspiking neurons neurons that only produce graded membrane potentials, this because it lacks voltage-gated sodium
  • Pacemaker potentials as in the heart, the faster the depolarization occurs, the faster it approaches the stimulus threshold that gives the action potential and a faster heart rate
  • Nodes of Ranvier In axons with myolin, the action potential only occurs at the points where the myolin is not present
