Whereas parathyroid hormone increases blood calcium levels, calcitonin decreases blood calcium levels. B) increases the level of calcium ions in the blood. Hypothyroidism is a condition that occurs if the thyroid gland does not produce enough of the thyroid hormone. Conventional long-term toxicity, reproduction, mutagenicity, and carcinogenicity studies have been performed in laboratory animals. Omissions?

For example, it inhibits the activity of the osteoclasts in bone tissue, thereby preventing the resorption (breakdown) of bone, and inhibits the reabsorption of calcium by the cells of the kidney, resulting in increased calcium excretion in the urine. [22] Salmon calcitonin is used for the treatment of: It has been investigated as a possible non-operative treatment for spinal stenosis. Inadequate iodine in the diet may lead to Calcitonin works to control calcium and potassium levels. However, since bone resorption and bone formation are coupled processes, eventually calcitonin's inhibition of osteoclastic activity leads to increased osteoblastic activity (as an indirect effect).
