Question

multiple choice question select the true statement regarding action potentials. an action potential can be conducted during the refractory period. action potentials are propagated down dendrites. action potentials vary in their intensity. an action potential is an all - or - nothing event.

Explanation:

Action potentials are 'all - or - nothing' events. During the refractory period, a new action potential cannot be initiated easily. Action potentials are propagated down axons, not dendrites. They are uniform in intensity and do not vary within a single neuron under normal conditions.

Answer:

An action potential is an 'all - or - nothing' event.
