dorsal motor nucleus

The dorsal motor nucleus of Vagus nerve.

They are transmitted through the dorsal motor nuclei of the vagi and then through the vagus nerve to the stomach.

The dorsal branch of the vagus originates in the dorsal motor nucleus and is considered the phylogenetically older branch.

Sensory stimuli from food activate dorsal motor nucleus of vagus nerve in the medulla (activating the parasympathetic nervous system).

By contrast, in humans, we found NK-ir perikarya located in the dorsal motor nucleus of the vagus, in which in the cat no immunoreactive cell bodies were found [ 15 ] .

Noradrenergic cell group A2 is a group of cells in the vicinity of the dorsal motor nucleus of the vagus nerve in the medulla that label for norepinephrine in primates and rodents.

However, in the rat, those authors did not find either NKA nor NKB in the dorsal motor nucleus of the vagus and in the nucleus prepositus hypoglossi, in which, in humans, we observed NK-ir structures.

Preganglionic parasympathetic neurons are in the medulla oblongata (forming visceral motor nuclei: the dorsal motor nucleus of the vagus nerve (dmnX), the nucleus ambiguus, and the salivatory nuclei), and in the sacral spinal cord.

A. Preganglionic Parasympathetic fibers (Preganglionic fibers) - These fibers have their cell bodies located in the dorsal motor nucleus of the vagus and they will synapse on the terminal ganglia in the walls of the esophagus.

The area postrema makes up part of the dorsal vagal complex, which is the critical termination site of vagal afferent nerve fibers, along with the dorsal motor nucleus of the vagus and the nucleus of the solitary tract.

That is, through integrated and antagonistic system with sympathetic outflow from the vasomotor center of the brainstem, the parasympathetic outflow arising from the nucleus ambiguus and dorsal motor nucleus of the vagus nerve acts to decrease cardiac activity in response to fast increases in blood pressure.
