satiety center
the bodys inability to regulate blood glucose levels within the normal range
diabetes mellitus
In type 1 diabetes mellitus, tissues cannot take up glucose effectively, causing blood glucose levels to become very high, a condition called
hyperglycemia
released from the alpha cells when the blood glucose levels are low
glucagon
released by the delta cells in response to food intake
somatostatin
main reproductive hormone in the male, which is secreted by the testes
