What is the target/function of releasing hormones? (RH) ANTERIOR LOBE; Regulates secretion of anterior pituitary hormones: stimulates secretion
What is the target/function of inhibiting hormones? (IH) ANTERIOR LOBE; Regulates secretion of anterior pituitary hormones: inhibits secretion
What is the target/function of ACTH? ADRENAL CORTEX; Stimulates secretion of cortisol and androgens and to a lesser extent aldosterone
What is the target/function of FSH? OVARIES/TESTES; In female: stimulates egg growth and estrogen secretion In male: stimulates sperm production
What is the target/function of LH? OVARIES/TESTES; In female: triggers ovulation and estrogen and progesterone secretion In male: stimulates testosterone secretion

What is the target/function of aldosterone? KIDNEYS; Decreases water & sodium loss in urine & returns them to the blood, but increases potassium urine loss
What is the target/function of cortisol? LIVER, MUSCLE AND CELLS INVOLVED IN BODY DEFENSES; Increases resistance to stress, increases blood glucose levels, & decreases internal inflammation
What is the target/function of insulin? MOST BODY CELLS; Promotes blood glucose uptake by most body cells, esp muscle and fat cells
What is the target/function of glucagon? LIVER; Increases blood glucose levels by stimulating the breakdown of glycogen
