Special visceral efferent doesn&;t include:
Correct Answer: Dorsal nucleus of the Xth cranial nerve
Description: Dorsal nucleus of the Xth cranial nerve is not a special Visceral Efferent Nuclei. The Dorsal vagal Motor nucleus is a &;General Visceral Efferent&; Nuclei that represents the origin of the preganglionic, parasympathetic fibers of the vagus nerve. Special Visceral Efferent Nuclei : (These nuclei supply striated muscles derived from the brachial arches) Neurons in the SVE nuclei in the brainstem are associated with the trigeminal(V), facial(VII), glossopharyngeal(IX), vagus(X), and cranial poion of the accessory (XI) nerves. The SVE nucleus associated with the vagus nerves glossopharyngeal and is the nucleus ambiguous. SVE Nuclei CN Muscles supplied Motor nucleus of the V nerve Mandibular nerve (V3) Muscles of mastication Nucleus of the VII nerve VII Muscles of the face Nucleus ambiguous IX Stylopharyngeus muscle Nucleus ambiguous X and XI Muscles of the soft palate, the pharynx, and larynx Cranial Nerve Nuclei: Efferent: General Somatic efferent General Visceral Efferent Special Visceral Efferent Occulomotor nucleus Trochlear nucleus Abducent nucleus Hypoglossal nucleus Edinger Westphal nucleus Lacrimatory nucleus Superior Salivatory nucleus Inferior Salivatory nucleus Dorsal nucleus of the vagus Motor nucleus of the trigeminal nerve Motor nucleus of the facial nerve Nucleus ambiguous Afferent: General Somatic Afferent General Visceral Afferent & Special Visceral Afferent Special Somatic Afferent Superior sensory nucleus of the trigeminal nerve Spinal nucleus of the trigeminal nerve Mesencephalic nucleus of the trigeminal nerve Nucleus of solitary tract (or tractus solitarius) Upper pa of the tractus solitarius is for special visceral afferent Lower pa of tractus solitarius is for General visceral afferent Cochlear nuclei Vestibular nuclei Ref: BDC 7th volume 4 Pgno: 50
