| A | B |
|---|
| Antidiuretic hormone (ADH) | Increases water absorption by the kidneys and therefore decreases urine output |
| Oxytocin (OT) | Stimulates contraction of smooth muscle of the uterus and release of milk by mammary glands |
| Thyroid stimulating hormone (TSH) | Stimulates release of thyroid hormones by thyroid gland |
| Adrenocorticotropic hormone (ACTH) | Stimulates production of glucocorticoids by adrenal cortex |
| Follicle stimulating hormone (FSH) | Controls egg and sperm production |
| Luteinizing hormone (LH) | Stimulates sex hormone production by testes/ovaries |
| Prolactin (PRL) | Stimulates milk production and secretion |
| Human growth hormone (hGH) | Working through an intermediate, IGFs, stimulates growth & maintenance of bone and muscle, cell division and protein synthesis |
| Melanocyte stimulating hormone | Regulates skin color in lower vertebrates, function in humans unknown |
| Thyroid hormones (T3 and T4) or thiiodothyronine and thyroxine | Increases metabolic rate, helps regulate growth and development |
| Calcitonin | Lowers blood calcium level |
| Parathyroid hormone (PTH) | Raises blood calcium level |
| Epinephrine/norepinephrine | Stimulate fight-or-flight reactions, raise blood glucose |
| Glucocorticoids (cortisol) | Raise blood glucose level, aid the body in resistance to stress |
| Insulin | Lowers blood glucose level (because glucose is transported into cells) |
| Glucagon | Raises blood glucose level (because glucose is released from cells into the blood) |
| Androgens (testosterone) | Stimulates development of male secondary sex characteristics and sperm production |
| Estrogens and progesterone | Stimulates development of female secondary sex characteristics and growth of uterine lining; maintain pregancy |
| Thymosins | Stimulate maturation of T lymphocytes;other immune system functions |
| Melatonin | Involved in patterns of waking and sleep |
| Mineralocorticoids (aldosterone) | Stimulate kidneys to reabsorb sodium and excrete potassium |
