The extracellular calcium-sensing receptor (CaR) plays a key role in the body's capacity to maintain a nearly constant level of the extracellular ionized calcium concentration. The parathyroid glands play an especially important role in calcium homeostasis through their capacity to sense even minute perturbations in the extracellular calcium concentration and to respond in ways that will normalize the level of extracellular calcium. In response to hypocalcemia, for example, in...
