According to the all-or-none law:
a. all axons in an area will fight at a given signal.
b. an axon moves from its resting state with various degrees of stimulation.
c. only sufficient electrical activity will cause the axon to fire.
d. there is a gradual buildup of electrical activity before an axon can fire.
I think it is either c or d because I know that once there is enough force to pull the trigger, a neuron fires.
According to the all-or-none law, the correct answer is c. Only sufficient electrical activity will cause the axon to fire.
To explain how to arrive at this answer, let's break down the options:
a. The statement that "all axons in an area will fight at a given signal" is not in line with the all-or-none law. The all-or-none law states that when a neuron reaches its threshold, it will fire with full strength, or not at all. It does not imply that all axons in an area will fire simultaneously.
b. The statement that "an axon moves from its resting state with various degrees of stimulation" is not consistent with the all-or-none law. The all-or-none law suggests that the axon either fires with maximum strength or not at all, regardless of the level of stimulation.
c. This statement aligns with the all-or-none law. The all-or-none law states that only when the electrical activity reaches a certain threshold will the axon fire an action potential. This means that if the stimulation is not sufficient to reach the threshold, the axon will not fire. But once the threshold is surpassed, the axon will fire with full strength, without gradations.
d. The statement that "there is a gradual buildup of electrical activity before an axon can fire" contradicts the all-or-none law. The all-or-none law implies that the firing of an axon is not a gradual process; it is an all-or-nothing response once the threshold is reached.
Therefore, the correct answer is c: only sufficient electrical activity will cause the axon to fire, in line with the all-or-none law.
