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
low glucose stimulates
lat hypothal
high glucose stimulates
ventromedial hypothalamus
retinohypothal fibers terminate in
suprachiasmatic nuc
medial forebrain bundle and dorsal long fascic go to
PAG and reticular formation and then terminate on parasym nuclei in brainstem and sym nuclei in SC
mammilothalamic tract terminates
in the ant nucleus of thalamus
fibers from lateral zone hypothal project to
DM nucleus of thalamus
