Question

How the action potential causes release of the acetylcholine neurotransmitter from the presynaptic neuron?

Answer 1

Neurotransmitter Release At Cholinergic Synapses.Cholinergic synapses are chemical synapses that that use acetylcholine molecules as theneurotransmitter. Synaptic transmission begins when an action potential or electrochemical impulse reaches the synaptic knob of a presynaptic neuron.
