Description

The action potential travels down the axon and reaches the pre-synaptic terminal depolarizing the membrane in the pre-synaptic terminal. The depolarization causes the voltage-gated Ca2+ channels to open allowing the influx of Ca2+ that signals the release of neurotransmitter into the synaptic cleft.
