Hypothalamus Anatomy and Hypothalamic Nuclei • Anterior hypothalamic nucleus - Body temperature, thermal regulation (heat dissipation), stimulates parasympathetic ns, destruction results in hyperthermia. • Paraventricular nucleus - Water balance & stress, produces ADH & oxytocin, destruction causes diabetes insipidus • Dorsal & lateral hypothalamic area - Water balance & stress, produces ADH & oxytocin • Posterior hypothalamic area - Shivering, thermal regulation, destruction causes inability to thermoregulate, stimulates the sympathetic CNS • Dorsomedial nucleus - GI tract, stimulation results in obesity and savage behavior • Lateral & medial preoptic nucleus - Blood pressure, contains sexually dimorphic nucleus, regulates release of gonadotropic hormones • Supraoptic nucleus - Water Balance • Ventromedial nucleus - Satiety center, destruction results in obesity & savage behavior By @rev.med #Hypothalamus #Anatomy #Nuclei #neurology #neuroanatomy #nucleus
