Parathyroid Hormone Christina Chan
Gland Chemical Class • Parathyroid Gland • Polypeptide
Target Tissue and Source of Control • bones and kidneys • CHIEF CELLS produce PTH • function: control concentration of calcium in blood
When Calcium concentration falls below normal. . . 1. chief cells secrete PTH 2. release of stored calcium from bone 3. enhanced reabsorption of calcium in kidneys 4. stimulation of calcitriol production at kidneys
Hyper/Hypo-Secretion • Hyperparathyroidism: PT gland produces too much PTH due to a tumor on PT gland • Hypoparathyroidism: when PT gland produces too little PTH
