Endocrine System Glands & Hormones

Hormone A chemical messenger that is produced at one site and carried by the blood to its site of action (target cells)

Pituitary Gland 1. ACTH (Adrenocorticotropic hormone) Stimulates adrenal glands to make Cortisol and aldosterone 2. ADH (Antidiuretic hormone) Causes kidneys to reabsorb more water preventing dehydration 3. GH (Growth hormone) (Causes bone and muscle growth) 4. TSH (Thyroid stimulating hormone) (Stimulates thyroid gland to make T 3 and T 4)

Pituitary Gland 5. LH (Luitenizing hormone) (Stimulates estrogen & progesterone secretion from ovaries & testosterone secretion from testes) 6. FSH (Follicle stimulating hormone) (Egg & sperm production) 7. Oxytocin (Causes uterine contractions) 8. Prolactin (milk production)

Pineal Gland • Melatonin (Initiates sleep)

Thyroid Gland T 3 (Triiodothyronine) (Controls metabolism) T 4 (Thyroxin) (Controls metabolism) • Calcitonin (Builds up bone to lower blood calcium)

Parathyroid Gland • PTH (Parathyroid hormone) (Breaks down bone to raise blood calcium)

Thymus Gland • Thymosin (Controls immune system)

Pancreas • Insulin (Allows glucose to enter cells; LOWERS blood glucose) • Glucagon (Stimulates liver to make glucose; RAISES blood glucose)

Adrenal Glands Medulla a. Epinephrine (adrenaline) (Increases: blood glucose, heart rate, blood pressure, breathing rate, & dilates bronchioles) b. Nor-epinephrine (nor-adrenaline) (Same as Epinephrine)

Adrenal Glands Cortex a. Cortisol (Stress released to increase blood glucose) b. Aldosterone (Controls salt & water balance) c. Androgens (small amounts of estrogen and testosterone)
