Acetylcholinesterase degrades acetylcholine into choline and acetate molecules. Choline is then transported back into the presynaptic terminal and used in the synthesis of new acetylcholine. Figure 13.1.
WebInhibitory signals work to cancel the signal. Every time an action potential is triggered in a neuron, that cell will release whatever types of neurotransmitter it has, because calcium cannot tell the difference between one vesicle and another. So neurons tend to have only one type of neurotransmitter – either excitatory OR inhibitory. http://www.ib.bioninja.com.au/standard-level/topic-6-human-physiology/65-neurons-and-synapses/neurotransmitters.html
