Cell bodies of pre-ganglionic parasympathetic neurons of CN X that innervate the heart meanwhile reside in the nucleus ambiguus, and additional cell bodies of the nucleus ambiguus give rise to the branchial efferent motor fibers of the vagus nerve (CN X) terminating in the laryngeal, and pharyngeal muscles, and musculus uvulae muscle.

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 It contains nerve cell bodies ofparasympathetic neurons of CN X that provide parasympathetic innervation to the gastrointestinal tract and lungs as well as other thoracic and abdominal organs These functions include among others bronchoconstriction and gland secretion 2 verification needed Dorsal nucleus of vagus nerveNuclei of origin of cranial motor nerves schematically represented lateral view X visible at bottom center 9 is vagus nerve and nucleusDetailsIdentifiersLatinnucleus posterior nervi vagi nucleus dorsalis nervi vagiNeuroNames755NeuroLex IDbirnlex 2642TA98A14 1 04 229TA26013FMA54585Anatomical terms of neuroanatomy edit on Wikidata Cell bodies of pre ganglionic parasympathetic neurons of CN X that innervate the heart meanwhile reside in the nucleus ambiguus and additional cell bodies of the nucleus ambiguus give rise to the branchial efferent motor fibers of the vagus nerve CN X terminating in the laryngeal and pharyngeal muscles and musculus uvulae muscle Contents 1 Additional images 2 See also 3 References 4 External linksAdditional images Edit nbsp Section of the medulla oblongata at about the middle of the olive nbsp The cranial nerve nuclei schematically represented dorsal view Motor nuclei in red sensory in blue nbsp Dorsal motor nucleus of Vagus with Lewy body pathologySee also EditVagovagal reflex gastrointestinal tract reflex circuits where afferent and efferent fibers of the vagus nerve Nucleus ambiguusReferences Edit Dorland s Illustrated Medical Dictionary Elsevier 2012 p 1300 ISBN 978 1 4160 6257 8 Patestas Maria Antoniou amp Gartner Leslie P 2006 A textbook of neuroanatomy Wiley Blackwell p 11 ISBN 978 1 4051 0340 4 External links EditMedEd at Loyola GrossAnatomy h n cn cn1 cn10 htm Overview at mcgill ca NIF Search Dorsal nucleus of vagus nerve permanent dead link via the Neuroscience Information Framework nbsp This neuroanatomy article is a stub You can help Wikipedia by expanding it vte Retrieved from https en wikipedia org w index php title Dorsal nucleus of vagus nerve amp oldid 1171739435, wikipedia, wiki, book, books, library,
