Parathyroid Hormone. Parathyroid hormone is the most important endocrine regulator of calcium and phosphorus concentration in extracellular fluid. This hormone is secreted from cells of the parathyroid glands and finds its major target cells in bone and kidney.Another hormone, parathyroid hormone-related protein, binds to the same receptor as parathyroid hormone and has major effects on development. This effect is mediated by stimulating tubular reabsorption of calcium. 2  Another effect of parathyroid hormone on the kidney is to stimulate loss of phosphate ions in urine.
