The reason provided is that prolactin induces the release of PTH related peptide which enhances bone resorption, but is still under investigation.[14][15][16]. There doesnt seem to be any effect on your body as a result of having too little calcitonin. This does not cause obvious symptoms in mild cases, but if levels rise too high, it can cause digestive upset, constipation, depression, lethargy, weakness, joint pain, and excessive thirst. B) increased retention of sodium ions at the kidney. When the kidneys cannot respond to ADH, __________ results.

A) insulin is released. D) GH. Calcitonin works to control calcium and potassium levels. It does this by inhibiting the activity of the osteoclasts, the cells that break down bone. When the osteoclasts break down bone tissue, the calcium enters the bloodstream. By preventing the breakdown of bone, calcitonin lessens the amount of calcium in the blood. Secretion of calcitonin is stimulated by: The hormone participates in calcium (Ca2+) metabolism. D) in some disease processes. C) growth hormone. B) glucagon Calcitonin also regulates the level of calcium and other mineral levels in the kidneys. To this end, this protein prevents the reabsorption of phosphate by the kidney and increases the kidneys reabsorption of calcium and magnesium, thus leading to increased calcium excretion via the urine.

When blood glucose levels rise, The heart is known to secrete all of the following hormones, except Theyre there to help you. A) increased levels of melanin. Ch 6 Communication, Integration, and Homeosta, David N. Shier, Jackie L. Butler, Ricki Lewis, Human Anatomy and Physiology Laboratory Manual, Elaine N. Marieb, Lori A. Smith, Susan J. Mitchell. Calcitonin also has significantly impacted molecular biology, as the gene encoding calcitonin was the first gene discovered in mammalian cells to be alternatively spliced, now known to be a ubiquitous mechanism in eukaryotes.[20][21]. Once in the bloodstream, thyroxine travels to the organs, like the liver and kidneys, where it is converted to its active form of triiodothyronine. E) are transported in the blood dissolved in the plasma. In a recent clinical study, subcutaneous injections of calcitonin have reduced the incidence of fractures and reduced the decrease in bone mass in women with type 2 diabetes complicated with osteoporosis.[32]. 2) A chemical grouping of hormones derived from arachidonic acid is the: 3) Which of the following hormones works by direct gene activation?
