Hypothalamic Nuclei Flashcards
Anterior hypothalamic nucleus is responsible for what?
dissipation of heat and cooling
anterior hypothalamic nucleus is regulated by?
parasympathetics
anterior hypothalamic nucleus injury would result in
hyperthermia
arcuate hypothalamic nucleus
regulates secretion of neuroendocrine hormores from the pituitary gland and inhibits lactation
arcute hypothalamic nucleus injury
neuroendocrine dysregulation
dorsomedial hypothalamic nucleus
regulates thrist and appetitie (which depends on your weight)
regulates cardiovascular response to stress and regulates the circadian ryhtmn
dorsomedial hypothalamic nucleus
hypophagia and hypodispia
lateral nucleus
regulates hunger
lateral nucelus is stimulated by?
inhibited by?
stimulated by grhelin which increases hunger
inhibited by leptin which will inhibit hunger
lateral nucleus injury
anorexia nervosa, failure to thrive, starvation
mammillary body
controls episodic memory
mammillary body injury
wernicke encephalopthy
paraventricular nucleus
regulates water balance and production of TRH, CRH, Somatostatin, ADH and oxytocin
paraventricular nucelus injury
diabeted insipidus
posterior hypothalamic nucleus
conservation of heat
posterior hypothalamic nucleus injury
hypothermia
preoptic nucleus
sexual function and secretion of gondotropic hormones
preoptic nucleus injury
kallman syndrome
suprachiasmatic nucleus
recieves visual stimuli from the retina and regulates the circadian ryhtmn
suprachiasmatic nucleus injury
sleep disorders
supraoptic nucleus
water balance
production of ADH and oxytocin
supra optic nucleus injury
diabetes insipidus
ventromedial hypothalamic nucleus
satiety (stimulated by leptin)
ventromedial hypothalamic nucleus injury
hyperphagia and obesity
