Which hormone acts on bone to release calcium into the blood? a. Thyroxine (T4) b. Thyrocalcitonin c. Triiodothyronine (T3) d. Parathormone ANS: D Parathormone, or parathyroid hormone, is produced and secreted by the parathyroid glands. Low calcium levels will stimulate release of parathormone, which increases the plasma level of calcium. Parathormone acts on the renal tubules to increase the excretion of phosphorus in the urine and to stimulate the reabsorption of calcium. Parathormone also acts on bone, causing the release of calcium from the bone into the bloodstream.

Which gland secretes epinephrine and norepinephrine? a. Thyroid b. Pituitary c. Pancreas d. Adrenal medulla ANS: D The adrenal medulla secretes epinephrine and norepinephrine.

Where in the body are mineralocorticoids and glucocorticoids produced? a. Adrenal cortex b. Adrenal medulla c. Pancreas d.
