Regulatory Hormones
- Hypothalamus
- Control release of hormones from anterior pituitary gland
Antidiuretic Hormone (ADH)
- Synthesized in Hypothalamus
- Released from Posterior Pituitary gland
- Causes kidneys to decrease urine output, thirst center to increase fluid intake.
- High dosage = vasoconstrictor
Oxytocin (OT)
- Synthesized in Hypothalamus
- Released from Posterior Pituitary Gland
- Contraction of smooth muscle of uterus
- Ejection of milk
- Increases feelings of emotional bonding
Thyroid-stimulating Hormone (TSH)
- Anterior Pituitary Gland
- Stimulates thyroid to release Thyroid Hormone
Prolactin (PRL)
- Anterior Pituitary Gland
- Mammary gland growth
- Breast milk production
- Increase Testosterone in males
Follicle-stimulating Hormone (FSH)
- Anterior Pituitary Gland
- Oocyte and follicle development
- Sperm production
Luteinizing Hormone (LH)
- Anterior Pituitary Gland
- Ovulation
- Testosterone synthesis in testes
Adrenocorticotropic Hormone (ACTH)
- Anterior Pituitary Gland
- Stimulates adrenal cortex to release cortizol
Growth Hormone (GH)
Somatostatin
- Anterior Pituitary Gland
- Releases growth factor (IGFs) from liver to induce growth
Melatonin
- Pineal Gland
- Circadian rhythm
- Sexual maturation
Thyroid Hormones
- Thyroid Gland
- Increase metabolic rate
- Increase heat production
Parathyroid Hormone (PTH)
- Parathyroid Glands
- Increases blood calcium levels
- Stimulates osteoclasts to release bone calcium
- Calcium reabsorption from urine
- Calcitriol Hormone
Calcitonin
- Thyroid Gland
- Decreases blood calcium levels
Thymosin, Thymulin, Thymopoetin
- Thymus
- Maturation of T-lymphocytes
Aldosterone
- Adrenal Cortex
- Regulates blood K+ and Na+ levels
Cortisol
- Adrenal Cortex

- Gonads
- Inhibits release of follicle-stimulating hormone
Estrogen and Progesterone
- Ovaries, Placenta
- Maturation and function of female reproductive system
- Development of the fetus
- Physical changes associated with pregnancy
Atrial Natriuretic Peptide (ANP)
- Heart
- Decreases blood pressure
Erythropoietin (EPO)
- Kidneys
- Increase production of Red Blood Cells
Angiotensinogen
- Liver
- Increased BP
- Vasoconstriction
- Decrease urine output
Insulin-like Growth Factor (IGFs)
- Liver
- Functions synergistically with growth hormone

- Skin
- Converted to calcitriol
- Increases calcium absorption from small intestines
Leptin
- Adipose Tissue
- Helps regulate food intake
Corticotropin-releasing Hormone (CRH)
- Hypothalamus
- Stimulates the release of Adrenocorticotropic Hormone (ACTH)
Growth Hormone Releasing Hormone (GHRH)
- Hypothalamus
- Stimulates release of GH
Growth Hormone Inhibiting Hormone (GHIH)
- Hypothalamus
- Inhibits the release of GH
Thyrotropin-releasing Hormone (TRH)
