Question
Match the following to their definition:
Depolarization
[ Choose ] Cardiomyocyte resting membrane potential Membrane potential returns to resting membrane potential Neuron resting membrane potential Time when no new action potential can be propagated, no matter the stimulus Membrane potential becomes more negative than resting membrane potential Time when a new action potential is inhibited but not impossible Membrane potential becomes less negative than resting membrane potential Skeletal muscle resting membrane potential
Repolarization
[ Choose ] Cardiomyocyte resting membrane potential Membrane potential returns to resting membrane potential Neuron resting membrane potential Time when no new action potential can be propagated, no matter the stimulus Membrane potential becomes more negative than resting membrane potential Time when a new action potential is inhibited but not impossible Membrane potential becomes less negative than resting membrane potential Skeletal muscle resting membrane potential
Hyperpolarization
[ Choose ] Cardiomyocyte resting membrane potential Membrane potential returns to resting membrane potential Neuron resting membrane potential Time when no new action potential can be propagated, no matter the stimulus Membrane potential becomes more negative than resting membrane potential Time when a new action potential is inhibited but not impossible Membrane potential becomes less negative than resting membrane potential Skeletal muscle resting membrane potential
Absolute Refractory Period
