'''Acetylcholine''' is a [[neurotransmitter]] found within the central and peripheral nervous systems (including the [[autonomic nervous system]]). It is one of the neurotransmitters responsible for excitatory neuronal transmission, as well as excitatory stimulation of [[skeletal]] muscle action potentials that produce contraction. In the autonomic nervous system, it is released from post-[[ganglion]]ic [[neuron]]s of the [[parasympathetic]] system, including the [[Vagus nerve]] that innervates the [[gastrointestinal system]] and [[heart]].
