What limits the maximum number of action potentials on an axon?
A) the relative refractory period
B) the diameter of the axon
C) the absolute refractory period
D) whether the axon is myelinated or not
E) the concentration of sodium within the cytoplasm of the cell

Question

Quizplus · Accepted Answer

The absolute refractory period limits the maximum number of action potentials on an axon because it is a time during which no new action potential can be initiated, regardless of the strength of the stimulus. This period ensures that each action potential is a discrete, all-or-nothing event and provides a direction to the propagation of the action potential.
