WebUses This medication is used to treat certain bone problems (such as Paget's disease, postmenopausal osteoporosis) and to reduce high blood levels of calcium. Calcitonin produces effects by binding to the calcitonin receptor ( CALCR) found in the bones, in the kidney, and regions of the brain [ 7 ].

A) a lack of response by target cells to insulin Each of the following hormones is an amino acid derivative, except The two lobes of the pituitary gland together produce how many hormones? C) thymosin. E) calcitonin is secreted. D) aldosterone 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).

Hypoglycermia is a stimulus for release of, 16. E) increases cyclic AMP concentration within thyroid follicle cells, Before the discovery of these glands, thyroid surgery often led to a rapid drop in blood calcium levels, which triggered muscle contractions and cardiac arrhythmias.
