Endocrine Glands & Their Hormones

QuestionAnswer
Anterior Pituitary GH (growth hormone) Promotes growth of all body tissues
Anterior pituitary TSH (thyroid-stimulating hormone) Stimulates thyroid gland to produce thyroid hormones
Anterior pituitary ACTH (adrenocorticotropic hormone) Stimulats adrenal cortex to produce cortical hormones, aids in protecting body in stress situations
Anterior pituitary PRL (prolactin) Stimulates milk secretion by mammary glands
Anterior pituitary FSH (folicle-stimulating hormone) Stimulates growth and hormone activity of ovarian follicles; stimulates growth of testes; promotes development of sperm cells
anterior pituitary LH (luteinizing hormone) Causes development of corpus luteum at site of ruptured ovarian follicle in female; stimulates testosterone secretion in male
Posterior pituitary ADH (antidiuretic hormone) Promotes reabsorption of water in kidney tubules; at high concentration stimulates constriction of blood vesels
Posterior pituitary Oxytocin Causes contration of uterine muscle; causes milk ejection from mammary glands
Thyroid Thyroxine (T4) and triiodothyronine (T3) Incease metabolic rate, influencing both plysical and mental activities; required for normal growth
Parathyroids PTH (parathyroid hormone) Regulates exchange of calcuim between blood and bones; increases calcuim level in blood
Adrenal medulla Epinephrine and norepinephrine Increase blood pressure and heart rate; activates cells influenced by sympathetic nervous system plus many not affected by sympathetic nerves
Adrenal cortex Cortisol (95% of glucocorticoids) Aids in metabolism of carbohydrates, proteins, and fats, active during stress
Adrenal cortex Aldosterone (95% of mineralocorticoids) Aids in regulating electrolytes and water balance
Pancreatic islets Insulin Needed for transport of glucose into cells; required for cellular metabolism of foods, especially glucose; decreases blood sugar levels
Pancreatic islets Glucagon Stimulates liver to release glucose, thereby increasing blood sugar levels
Testes Testoserone Stimulates growth and developent of sexual organs (testes, penis) plus development of secondary sexual characteristics, such as hair growth on body and face and deepening of voice, stimulates maturation of sperm cells
Ovaries Estrogens (eg estradiol) Stimulates gorwth of primary sexual organs (uterus, tubes) and development of secondary sexual organs, such as breasts, plus changes in pelvis to ovoid, boader shape
Thymus Thymosin Promotes growth of T cells active in immunity
Pineal Melatonin Regulates mood, sexual development, and daily cycles in response to the amount of light in the environment
