arcuate nucleus
hormone secreted by an empty stomach to signal brain for hunger
ghrelin
hunger-triggering hormone secreted by the hypothalamus
orexin
hormone secreted by pancreas; controls blood glucose
insulin
protein hormone secreted by fat cells; when abundant causes brain to increase metabolism & decrease hunger

sexual response cycle

excitement
second stage of sexual response cycle
plateau
third stage of sexual response cycle
orgasm
fourth stage of sexual response cycle
resolution
resting period in which a person cannot achieve orgasm
refractory period
sensory receptors activated by stimuli that potentially damage/threaten the body
nociceptors
the part of the brain that releases hormones to stop hunger
ventromedial hypothalamus
