Set One: Hormones Steroids and Peptides

-Anterior Pituitary
-Growth of All Cells, inhibited by somatostatin
-peptide hormone

-Anterior Pituitary
-Stimulates adrenal cortex to release aldosterone etc.
-peptide hormone

-Anterior Pituitary
-In females it promotes ovaries to develop follicles, in males it stimulates sperm production (spermatogenesis)
-peptide hormone

-Anterior pituitary
-Causes ovulation & development of corpus luteum, stimulate estrogen and testosterone secretion (men).
-peptide

-Anterior Pituitary
-Stimulates release of T3 and t4 in thyroid via 2nd messenger cAMP.
-peptide

-Anterior Pituitary
-Promotes production of milk in breasts
-peptide

-Posterior Pituitary
-Milk ejection and uterine contraction
-peptide hormone (all pituitary makes peptide hormones)

-Posterior pituitary
-Targets kidney to increase water reabsorption, increases blood pressure (less urine). Also called Vasopressin; coffee and beer are ADH blockers
-peptide

-Made in Adrenal Cortex
-Increases renal reabsorption of sodium in distal tubule, while increasing K+ excretion. Causes a net increase of particles in plasma, which leads to higher blood pressure.
-Steroid

-Adrenal Cortex
-During stress it increases blood levels of carbohydrates (glucose), proteins, and fats. Also stimulates gluconeogenesis while decreasing inflammation.
-steroid hormone

-Adrenal Medulla
-Stimulates Sympathetic Actions. Catecholamines. Vasoconstrict organs and vasodilate skeletal muscle.
-Neither, it's a tyrosine derivative that acts via a 2nd messenger cAMP. Its also water soluble. So kind of like a peptide

-Thyroid
-Increases basal metabolic rate. regulated by TSH, it increases gene transcription in nearly all cells of body.
-It is lipid soluble, carried by plasma protein carriers; so it acts like a steroid, but it isn't one. Thyroxine is a peptide hormone, but it's hydrophobic enough to enter cells. It binds to a receptor in the nucleus.

-Thyroid gland
-Lowers blood calcium (calci-bone-in), decreases osteoclast activity.
-It is a large peptide hormone

-Parathyroid Glands
-Increases serum calcium levels but stimulating osteoclasts, and increases calcium reabsorption by kidneys and small intestine.
-Peptide Hormone

-Pancreas Beta Cells "Located behind stomach"
-Promotes entry of glucose into cells by making them more permeable to glucose, decreasing blood glucose level.
-Peptide
