How does the refractory period contribute to the propagation of action potentials?

Option: 1

It increases the speed of action potential propagation along the axon

Option: 2

It ensures that action potentials only travel in one direction along the axon

Option: 3

It allows for the formation of new synapses between neurons


Option: 4

It has no effect on the propagation of action potentials

Answers (1)


The refractory period ensures that an action potential can only travel in one direction along the axon, from the cell body to the axon terminal. This is because the region of the axon behind the action potential is in its absolute refractory period and cannot generate another action potential until the membrane potential returns to its resting state.

Option b is the correct answer.
