Thyroid gland secretes two important hormones, thyroxine (TJ and triiodothyronine (Tj). The third hormone, calcitonin secreted from interstitial cells is physiologically different and is responsible for the regulation of calcium metabolism. [Pg.293]

Fig. 1.46. Alternative polyadenylation in the expression of calcitonin genes of rat. The primary transcript of the calcitonin gene possesses two polyadenylation sites. One site is nsed in the processing of RNA in the thyroid, another site in the brain, and yet another in nerve tissne. The translation of the two mRNAs creates two pre-hormones, from which two different polypeptide hormones (calcitonin and the calcitonin-related peptide", or CGRP) are created via proteolysis.

Peptide Hormones Peptide hormones may have from 3 to 200 or more amino acid residues. They include the pancreatic hormones insulin, glucagon, and somatostatin, the parathyroid hormone, calcitonin, and all the hormones of the hypothalamus and pituitary (described below). These hormones are synthesized on ribosomes in the form of longer precursor proteins (prohormones),... [Pg.886]

The major location of calcium in the body is in the skeleton, which contains more than 90% of the body calcium as phosphate and carbonate. Bone resorption and formation keeps this calcium in dynamic equilibrium with ionized and complexed calcium in blood, cellular fluids and membranes. Homeostasis is mainly regulated by the parathyroid hormone and vitamin D which lead to increased blood calcium levels, and by a thyroid hormone, calcitonin, which controls the plasma calcium concentration J5 Increasing the concentration of calcitonin decreases the blood calcium level, hence injections of calcitonin are used to treat severe hyperalcaemia arising from hyperparathyroidism, vitamin D intoxication or the injection of too high a level of parathyroid extract. High levels of calcitonin also decrease resorption of calcium from bone. Hypocalcaemia stimulates parathyroid activity, leading to increased release of calcium from bone, reduction in urinary excretion of calcium and increased absorption of calcium from the intestine. Urinary excretion of phosphate is enhanced. [Pg.188]

PTH works with two other primary hormones— calcitonin and vitamin D—in regulating calcium homeostasis. These three hormones, as well as several other endocrine factors, are all involved in controlling calcium levels for various physiologic needs. How these hormones interact in controlling normal bone formation and resorption is of particular interest to rehabilitation specialists. Regulation of bone mineral homeostasis and the principal hormones involved in this process are presented in the following section. [Pg.465]

Know the effects of parathyroid hormone, calcitonin, and vitamin D in controlling calcium and phosphate metabolism. Know what controls the levels of such hormones in the bloodstream. [Pg.391]

Q2 Thyroxine (T4), the major hormone secreted together with triiodothyronine (T3). T3 is more active metabolically than T4. In addition the hormone calcitonin is secreted by the medullary cells of the thyroid gland. [Pg.143]

In addition to the role of bone mineral as a structural component of bone, it can be regarded as a major reserve of calcium for the body. In an adult, the skeleton contains 25 mol of calcium, whereas the total extracellular fluids contain only about 25 mmol. Parathyroid hormone, calcitonin, and calcitriol regulate the... [Pg.94]

Calcium is essential for the normal growth and development of the body, especially (in the form of calcium phosphate) of the bones and teeth. Its level in the blood is regulated by the opposing actions of the thyroid hormone calcitonin, and the parathyroid hormone parathormone. Its uptake from food is enhanced by vitamin D (calciferol). Forms of calcium used therapeutically include the folinic acid supplement calcium foiinate, and the mineral supplements calcium bicarbonate, calcium carbonate, calcium gluconate and calcium lactate. [Pg.182]
