Editing Motor neuron (section)

==== General visceral motor neurons ====
These motor neurons indirectly innervate [[cardiac muscle]] and [[smooth muscles]] of the [[viscera]] ( the muscles of the [[arteries]]): they [[synapse]] onto neurons located in [[ganglia]] of the [[autonomic nervous system]] ([[Sympathetic nervous system|sympathetic]] and [[parasympathetic]]), located in the [[peripheral nervous system]] (PNS), which themselves directly innervate visceral muscles (and also some gland cells).

In consequence, the motor command of [[skeletal muscle|skeletal]] and branchial muscles is ''monosynaptic'' involving only one motor neuron, either ''somatic'' or ''branchial'', which synapses onto the muscle.  Comparatively, the command of [[visceral muscles]] is ''disynaptic'' involving two neurons: the ''general visceral motor neuron'', located in the CNS, synapses onto a ganglionic neuron, located in the PNS, which synapses onto the muscle.

All vertebrate motor neurons are [[cholinergic]], that is, they release the neurotransmitter [[acetylcholine]]. Parasympathetic ganglionic neurons are also cholinergic, whereas most sympathetic ganglionic neurons are [[Norepinephrine|noradrenergic]], that is, they release the neurotransmitter [[noradrenaline]].
