Question | Answer |
---|---|
ADH | Anti-diuretic hormone |
Posterior pituitary gland | anti-diuretic hormone, and oxytocin |
ADH | increases the reabsorption of water by kidney tubules, which decreases the amount of fluid formed |
Oxytocin | stimulates contraction of the uterus at the end of pregnancy, stimulates mammary glands |
FSH | Follicle Stimulating Hormone |
FSH stimulates (women) | production of eggs in the ovary |
TSH | Thyroid-stimulating hormone |
TSH stimulates | the thyroid, causes it to secrete more thyroxine and T3 |
ACTH | Adrenocorticotropic hormone |
ACTH increases | the secretion of cortisol from the adrenal gland |
PRL | Prolactin |
PRL targets | the mammary glands |
GH | Growth hormone |
GH increases | protein synthesis, rate of mitosis, increases the use of fats |
LH | Luteinizing hormone |
LH affects (women) | causes ovulation |
LH affects (men) | increases secretion of testosterone by testes |
FSH stimulates (men) | sperm production in testes |
Thyroid gland secretes | Thyroxine (T4) and triiodothyronine (T3) and calcitonin |
T3 and T4 affect | metabolism/energy production |
Calcitonin | decreases amount of calcium that goes from bones to blood |
PTH | parathyroid hormone |
PTH affects | causes more calcium from bone to blood, increases amount of calcium absorbed in small intestine |
PTH is stimulated by | hypocalcemia |
Adrenal medulla | secretes epinephyrine and norepinephrine |
Norepinephrine causes | vasoconstriction in skin and skeletal muscles |
Epinephrine causes | increase in heart rate and force of hearbeat, causes vasodilation in skeletal muscles, dilates the bronchioles, decreases peristalsis, and increases energy production |
Aldosterone | increases the reabsorption of sodium and the excretion of potassium by the kidney tubules |
Cortisol | decreases inflammation |
Cortisol is released during | psychosocial stress |
Somatostatin | decreases secretion of insulin/glucagon |
Estrogen | promotes the maturation of the ovum in the ovarian follicle and stimultes the growth of blood vessels in the endometrium |
Estrogen is stimulated by | FSH |
Progesterone | promotes the storage of lycogen and the further growth of blood vessels in the endometrium, which thus become a potential placenta. It also influences the secretory cells of the mammary glands |
Progesterone is stimulated by | LH |
Inhibin (women) | decreases the secretion of FSH by the anterior pituitary gland and GnRH by the hypothalamus |
Testosterone | Steroid hormone secreted by the interstitial cells of the testes |
Testosterone is stimulated by | LH |
Inhibin (men) | decreases the secretion of FSH |
Inhibin is stimulated by | increased testosterone |
PGs | Prostaglandins |
PGs are involved in | inflammation, pain mechanisms, blood clotting, vasoconstriction and vasodilation, contraction of the uterus, reproduction, secretion of digestive glands and nutrient metabolism. |
