A(n)_______ is a subthreshold change in membrane potential within the cell body that decays as it travels away from its point of origin.
A) action potential
B) hyperpolarization
C) polarization
D) depolarization
E) graded potential

Question

Quizplus · Accepted Answer

A graded potential is a change in the membrane potential that varies in size, depending on the size of the stimulus that elicited it. It decreases in magnitude as it spreads out from the point of origin, unlike an action potential, which maintains its magnitude.
