Once a nerve impulse is generated at the initial segment of the axon, it will continue down the entire length of the axon. place the events below in the correct order for what happens next.
bind to their receptors (some diffuses out of the cleft; some is broken down)
is released into the synaptic cleft
+ ions cause synaptic vesicles to fuse with the plasma membrane
(ligand-gated ion channels in this case) open
potential arrives at the terminal knobs (axon terminals)
+ ions flood into the terminal knobs
depolarization from the action potential causes voltage-gated ca2+channels to open
flow into/out of the postsynaptic cell causing a depolarization or hyperpolarization (depends on the channel and the ions that are flowing)
