The dorsal nucleus of the vagus nerve (or posterior motor nucleus of vagus) is a cranial nerve nucleus for the vagus nerve that arises from the floor of the fourth ventricle. It mostly serves parasympathetic vagal functions in the heart, gastrointestinal tract, lungs, and other thoracic and abdominal vagal innervations.
