Collagen and calcium salts in osteocytes
WebCalcium ions are crucial for many functions of the body! Parathyroid release is stimulated by hypocalcemia (low [Ca2+]) and inhibited by hypercalcemia (high [Ca2+]). Parathyroid hormone targets bone (in addition to other tissue) during hypocalcemic conditions to help raise calcium levels in fluids of the body. When calcium levels return to ...
