The motor portion of the autonomic nervous system (ANS), sympathetic and parasympathetic, are characterized by a two-neuron chain. The pre-ganglionic nerve cell body is located in the and the postganglionic nerve cell body is located in .

The Autonomic Nervous System (ANS) is a motor function system for visceral organs, blood vessels and secretory glands. The ANS is divided into a sympathetic and parasympathetic nervous system, which consists of a motor pathway, composed of two neurons: pre-ganglionic and post-ganglionic.

The cell bodies of pre-ganglionic neurons are located in the cerebellar trunk or spinal cord. These neurons secrete mainly acetylcholine.

Postganglionic neurons, in turn, have their cell bodies located in the ganglia, and are responsible for sending unmyelinated axons (absence of the myelin sheath) and secreting norepinephrine.

The motor portion of the autonomic nervous system (ANS), sympathetic and parasympathetic, are characterized by a two-neuron chain. The pre-ganglionic nerve cell body is located in the ____________ and the postganglionic nerve cell body is located in ____________.
