Question

The action potential (spike) obeys the all or none law.

• A. True
• B. False

Answer 1

The correct option is A True

The all-or-none law states that the action potential does not occur without sufficient stimulus, but once it starts, they cannot be stopped. Every action potential causes the same amount of voltage change in the neuron's interior. There are no large or small action potentials, only larger and small stimuli.

Thus the action potential obeys the all or none law.

So, the given statement is true.
