The dorsal nucleus of vagus nerve (or posterior nucleus of vagus nerve or dorsal vagal nucleus or nucleus dorsalis nervi vagi or nucleus posterior nervi vagi) [1] is a cranial nerve nucleus of the vagus nerve (CN X) situated in the medulla oblongata of the brainstem ventral to the floor of the fourth ventricle.
The dorsal nucleus of vagus nerve – which sends parasympathetic output to the viscera, especially the intestines The nucleus ambiguus – which gives rise to the branchial efferent motor fibers of the vagus nerve and preganglionic parasympathetic neurons that innervate the heart
Dorsal cochlear nucleus, a cortex-like structure on the dorso-lateral surface of the brainstem; Dorsal nucleus of vagus nerve, a cranial nerve nucleus for the vagus nerve; Dorsal raphe nucleus; Lateral dorsal nucleus of thalamus; Medial dorsal nucleus of thalamus; Posterior thoracic nucleus (or dorsal nucleus), is a group of interneurons found ...
The solitary nucleus receives general visceral and special visceral inputs from the facial nerve (CN VII), glossopharyngeal nerve (CN IX) and vagus nerve (CN X); it receives and relays stimuli related to taste and visceral sensation. It sends outputs to various parts of the brain, such as the hypothalamus, thalamus, and reticular formation ...
Fibers cross over to and join the vagus nerve in the jugular foramen. [8]: 86–88 Sensory cell bodies are located in the inferior jugular ganglion, [9] and the fibers terminate in the solitary nucleus. [8]: 86–88 Parasympathetic fibers to segments of the trachea and esophagus in the neck originate in the dorsal nucleus of the vagus nerve. [9]
The vagal trigone (ala cinerea) is a triangular eminence upon the rhomboid fossa produced by the underlying dorsal nucleus of vagus nerve. [1] The vagal trigone is separated from the area postrema by a narrow strip of thickened ependyma – the funiculus separans. [2]
The posterior vagal trunk is one of the two divisions (the other being the anterior vagal trunk) into which the vagus nerve splits as it passes through the esophageal hiatus to enter the abdominal cavity. [1] The anterior and posterior vagal trunks together represent the inferior continuation of the esophageal nervous plexus inferior to the ...
The Posterior Bronchial Branches (rami bronchiales posteriores; posterior or dorsal pulmonary branches), more numerous and larger than the anterior, are distributed on the posterior surface of the root of the lung; they are joined by filaments from the third and fourth (sometimes also from the first and second) thoracic ganglia of the sympathetic trunk, and form the posterior pulmonary plexus.
