The Inability of Neurons to Generate Only a Part of an Action

Question

The inability of neurons to generate only a part of an action potential is called
A) Latency
B) Refractory period
C) Stimulus-latency relation
D) Excitability
E) All-or-none law

Accepted Answer

The all-or-none law states that a neuron either does not respond at all or it responds completely by generating a full action potential. This principle explains why neurons cannot generate only a part of an action potential.
