#7. System Physiology – Animal

no action potential will be initiated
an action potential will be initiated and proceed only in the normal direction toward the axon terminal
an action potential will be initiated and proceed only back toward the axon hillock
two action potentials will be initiated, one going toward the axon terminal and one going back toward the hillock
