Text
At a chemical synapse, a/an {{c3::action potential}} triggers {{c4::voltage gated calcium channels}} to open at the {{c2::presynaptic neuron}} which starts a cascade to release {{c1::neurotransmitters}}.
Extra
These molecules bind to receptors on the postsynaptic cell and make it more or less likely to fire an action potential
