WebAcetylcholine is an important neurotransmitter in the central nervous system, in the somatic nervous system, where it is released at the neuromuscular junction, and in the autonomic nervous system. It is released from preganglionic nerves as well as from postganglionic parasympathetic nerves and also from some postganglionic sympathetic nerves.
WebInhibitors of acetylcholinesterase are the most effective means to elevate acetylcholine either at cholinergic neurons or at the neuromuscular junction.
