Calcitonin comes from the thyroid, the butterfly-shaped gland in your throat.
Calcitonin is a 32 amino acid peptide cleaved from a larger prohormone. It contains a single disulfide bond, which causes the amino terminus to assume the shape of a ring. Alternative splicing of the calcitonin pre-mRNA can yield a mRNA encoding calcitonin gene-related peptide; that peptide appears to function in the nervous and vascular systems. The calcitonin receptor has been cloned and shown to be a member of the seven-transmembrane, G protein-coupled receptor family

The hormone is called as calcitonin. This hormone is secreted by the parathyroid glands.

The abbreviation for calcitonin is CT.
Calcitonin decreases calcium levels in the blood. A good way to remember it is "Calcitonin tones down the calcium."Calcitonin (just remember calciTONin, tones down blood calcium)
Calcitonin is a 32-amino acid linear polypeptide hormone which is secreted in human beings primarily by the parafollicular cells (also known as C-cells) of the thyroid, it regulates calcium levels in the body
Calcitonin injections have no effect on vertebral bone density...it is anticipated when doing the experiment that there would be...but there is not. (Marieb)
Osteoclast activity is decreased when calcitonin is present. Calcitonin inhibits bone resorption by osteoclasts, leading to decreased breakdown of bone tissue.
Parafollicular cells of the thyroid gland produce calcitonin.
Parathyroid hormone (PTH) directly antagonizes the effect of calcitonin. Calcitonin and PTH have opposing effects on bone metabolism, with calcitonin working to decrease calcium levels in the blood, while PTH works to increase calcium levels.
