phys Flashcards
anterior area hypothal
paraventricular nuc, anterior nuc, supraoptic nuc, suprachiasmatic nuc
middle/tuberal area hypothal
arcuate nuc, ventromedial nuc, dorsomedial nuc
posterior area hypothal
posterior nuc, mammillary body
ventromedial nuclei
inhibit eating and drinking, involved in satiety
arcuate nuclei
secrete releasing/inhibiting hormones
mamillary body
consolidation of memory
preoptic and anterior nuclei
heat loss, response to heat, parasympathetic activity, sleep
suprachiasmatic nuclei
circ rhythms, secretes releasing/inhibiting hormones
supraoptic nuclei
secrete hormones - oxytocin and vasopressin
paraventricular nuclei
magnocellular cells - secrete hormones; parvocellular - secrete releasing hormones
posterior nucleus
heat gain/conservation, response to cold, sympathetic activity, arousal/wakefulness
leptin inhibits
medial arcuate nuc (which stim the lateral hypothal)
leptin stimulates
lat arcuate nuc - paravent nucleus - ventromedial hypothal loop
GI stretch inhibits
medial arcuate nuc (which stim the lateral hypothal)
ghrelin inhibits
lat arcuate nuc - paravent nucleus - ventromedial hypothal loop
