Problem: Put these events in the order that they occur during nerve impulse transmission. Start with the events that occur at the axon hillock and end with the events that occur at the synapse.
Question options: The impulse reaches the axon hillock and when threshold potential is reached an impulse is propagated down the axon.
Neurotransmitter molecules bind to receptors expressed on the dendrite membrane of the post-synaptic neuron. Synaptic vesicles containing neurotransmitter molecules fuse with the membrane of the axon terminal.
K+ channels open and K+ exits the cell resulting in repolarization.
An impulse arrives at the axon terminal.
Na+ channels open and Na+ enters the axon resulting in depolarization.
