Question

Quizplus · Accepted Answer

Graded potentials are changes in membrane potential that vary in strength based on the strength of the stimulus. This is in contrast to action potentials, which have a fixed threshold for initiation and always have the same magnitude. Equilibrium potential refers to the membrane potential at which there is no net movement of a particular ion across the membrane. Resting potential refers to the membrane potential of a neuron when it is not undergoing any synaptic inputs. Reversal potential refers to the membrane potential at which an ion will not flow across the membrane when the electrochemical gradients for that ion are equal and opposite.
