Document Summary

Identify locations of the cranial nuclei in the brainstem (for each cn and each of its modalities) Function = basal regulation of body processes, site of cn nuclei. Somatic motor (gse) - skeletal mm derived from somites. Branchial motor (sve) - skeletal mm derived from pharyngeal arches. Visceral motor (gve) - parasympathetics innervated smooth muscle. Chemosensory (sva) - taste buds from tongue, palate, oropharynx, epiglottis. Viscerosensory (gva) - pharynx, larynx, interoceptive information from thoracoabdominal, carotid body/sinus. Somatic sensory (gsa) - general sensation (pain, temp, touch, proprioception) Special somatic sensory (ssa) - inner ear receptors. Taste (epiglotti thorax/ abdom en viscera (distent ion) hypoglossal.
