Definition Epinephrine (adrenal medulla) and norepinephrine (nerve endings) are released by the sympathetic nerve system and result in gluconeogenesis, glycogenolysis, lipolysis, and glucagon release (in addition to their hemodynamic effects). Cortisol (release from the adrenal cortex) also leads to gluconeogenesis, adipocyte sensitization (to growth hormone and catecholamines), blocks the anti-proteolytic actions of insulin, and also […]
