ventral posterior nucleus ventral posterior nucleus the ventral posterior nucleus is the somato-sensory relay nucleus in thalamus of the brain. ventral posterior nucleusthalamic nuclei: mng = midline nuclear groupan = anterior nuclear group md = medial dorsal nucleus vng = ventral nuclear group va = ventral anterior nucleus vl = ventral lateral nucleus vpl = ventral posterolateral nucleus vpm = ventral posteromedial nucleus lng = lateral nuclear group pul = pulvinar mth = metathalamus lg = lateral geniculate nucleus mg = medial geniculate nucleusthalamic nucleidetailspart ofthalamusidentifierslatinnucleus ventralis posterior thalamineuronames343neurolex idbirnlex_1116anatomical terms of neuroanatomy input and output the ventral posterior nucleus receives neuronal input from the medial lemniscus, spinothalamic tracts, and trigeminothalamic tract. it projects to the somatosensory cortex and the ascending reticuloactivation system. subdivisions the ventral posterior nucleus is divided into: ventral posterolateral nucleus, which receives sensory information from the body. ventral posteromedial nucleus, which receives sensory information from the head and face via the trigeminal nerve. ventral intermediate nucleus, implicated in oscillatory tremor generation in parkinson's disease and essential tremor. function functions in touch, body position, pain, temperature, itch, taste, and arousal. modulates tremor in certain pathology. additional images thalamus thalamus anatomy of the diencephalon of the human brainepithalamussurface pineal gland habenula habenular trigone habenular commissure grey matter pretectal area habenular nuclei subcommissural organ thalamussurface stria medullaris of thalamus thalamic reticular nucleus taenia thalami grey matter/nuclei paired: an ventral va/vl vp/vpm/vpl lateral ld lp pulvinar nuclei metathalamus mg lg p cell m cell k cell midline: md intralaminar centromedian midline nuclear group interthalamic adhesion white matter mammillothalamic tract pallidothalamic tracts ansa lenticularis lenticular fasciculus thalamic fasciculus pcml medial lemniscus trigeminal lemniscus spinothalamic tract lateral lemniscus dentatothalamic tract acoustic radiation optic radiation subthalamic fasciculus anterior trigeminothalamic tract medullary laminae hypothalamussurface median eminence/tuber cinereum mammillary body infundibulum grey matterautonomic zones anterior (parasympathetic/heat loss) posterior (sympathetic/heat conservation) endocrine posterior pituitary: paraventricular magnocellular neurosecretory cell parvocellular neurosecretory cell supraoptic oxytocin/vasopressin other: arcuate (dopamine/ghrh) preoptic (gnrh) suprachiasmatic (melatonin) emotion lateral ventromedial dorsomedial white matter afferent stria terminalis medial forebrain bundle retinohypothalamic tract efferent mammillothalamic tract dorsal longitudinal fasciculus pituitary posterior is diencephalon, but anterior is glandular subthalamus subthalamic nucleus zona incerta nuclei campi perizonalis (fields of forel)
