Vagus nerve Anatomy Animation / 10th Cranial nerve Origin, Course, Nuclei, Branches & Functions - Neuroanatomy Nuclei ---------- Dorsal nucleus - sends parasympathetic fibers to the intestines Nucleus ambiguus - sends efferent motor and parasympathetic fibers to the heart Solitary nucleus - receives special gustatory afferent from the tongue and visceral afferent fibers from organs Spinal trigeminal nucleus - receives general sensory afferent fibers Branches --------------- In the jugular fossa: meningeal, auricular branches In the neck: pharyngeal, superior laryngeal, recurrent laryngeal nerves; superior cardiac branches In the thorax: inferior cardiac nerve, anterior bronchial branches, posterior bronchial branches, esophageal branches In the abdomen: gastric, celiac and hepatic branches Field of innervation ------------------------------- General sensory afferent fibers - sensory information from larynx, auricle, external acoustic meatus, dura
