Acetylcholine is a chemical neurotransmitter used by the terminal endings of neurons to carry information across the synaptic cleft, which is the space between two nerve cells. It is released by autonomic preganglionic, parasympathetic postganglionic fibers and by all lower motor neurons that innervate skeletal muscles.
Acetylcholine is formed from choline, by an enzymatic reaction with coenzyme A. Choline must be obtained from the diet. The neurotransmitter plays an important role in learning and memory.
