When a nerve impulse reaches the presynaptic nerve terminal of a cholinergic synpase, it stimulates the release of the neurotransmitter, ACh (Figure 1), into the synaptic cleft. ACh diffuses across the cleft to the postsynaptic nerve terminal, where it binds reversibly to acetylcholine receptors embedded in the membrane of the postsynaptic nerve terminal. The binding of ACh to the receptors triggers a nerve impulse in the postsynaptic neuron. Finally AChE, anchored to the membrane of the postsynaptic nerve terminal (Figure 2), hydrolyzes ACh to acetate and choline, resulting in the termination of neurotransmission. | When a nerve impulse reaches the presynaptic nerve terminal of a cholinergic synpase, it stimulates the release of the neurotransmitter, ACh (Figure 1), into the synaptic cleft.
