Presynaptic M 2 receptors inhibit Ca 2+ influx and inhibit neurotransmitter release in most organs. Via this mechanism, M 2 receptors mediate some of the antagonistic interactions ... WebAt the presynaptic region the nerve impulse briefly opens calcium channels, promoting a Ca2+ influx that triggers neurotransmitter release by exocytosis or similar mechanisms. Immediately the released neurotransmitter molecules diffuse across the synaptic cleft and bind receptors at the postsynaptic region.
