dorsal motor nucleus of the vagus

A nucleus of the visceral motor column in the hindbrain; it lies in the floor of the fourth ventricle lateral to the hypoglossal nucleus. The dorsal motor nucleus of the vagus is the origin of preganglionic parasympathetic axons via which the vagus nerve (CN X) modulates secretory activity in the gastrointestinal system.
