What will be an ideal response?
Graded potentials are temporary, localized changes in resting membrane potentials that decrease with distance away from the stimulus. In response to sufficiently large graded potentials, action potentials are generated. Action potentials begin in one location and spread along the surface of an axon toward the axon terminals.
