Verified step by step guidance

Understand the concept of action potentials and graded potentials. Action potentials are all-or-nothing events that occur when a neuron sends information down an axon, away from the cell body. They are identical in size and duration once triggered.

Graded potentials, on the other hand, are changes in membrane potential that vary in size. They occur in the dendrites and cell body of a neuron and can be larger or smaller depending on the strength of the stimulus.

Recognize that action potentials are consistent in magnitude and duration, regardless of the strength of the stimulus, due to the all-or-nothing principle.

Graded potentials are variable and can summate to reach the threshold needed to trigger an action potential. They are influenced by the intensity of the stimulus.

Based on this understanding, identify that the correct pairing is 'Action potentials are all identical, whereas graded potentials can be larger or smaller depending on the level of stimulation.'
