1 Calcium homeostasis: A. The parathyroid gland monitors the calcium level in the blood to keep the blood level in a very close range (8.8 -10.2 mg/dl). (Anything outside that range is abnormal and should be investigated. So, if a doctor tells you your calcium is “just slightly elevated” at 10.6 and cannot be the cause of your depression, fatigue, lack of concentration, etc. Get another doctor. Even if you have no symptoms and your calcium level is elevated, you have Hypercalcemia and you have a parathyroid tumor. Elevated calcium is never normal and almost always due to a parathyroid adenoma) 1. Low blood calcium stimulates the parathyroid glands to secrete PTH (parathyroid hormone). PTH ultimately brings about an elevation of the blood calcium level. This comes about because osteoclasts take calcium from bone and transfers it to the blood. How is this done? a. PTH stimulates the monocyte – macrophage line of blood cells to differentiate into osteoclasts. The more osteoclasts, the more bone can be
