Meaning and Definition
A polypeptide hormone secreted by the C-cells of the thyroid gland in mammals, which lowers blood calcium levels by inhibiting bone resorption.
A specific hormone regulating calcium and phosphate metabolism; a type of calcitonin originally believed to be produced only by the thyroid gland (though found in other tissues in other species).
Dialectal Variation
British vs American Usage
Differences
No significant spelling or usage differences. Both varieties use the term strictly in medical/biological contexts.
Connotations
Purely technical/clinical in both varieties.
Frequency
Equally low frequency in both regions, confined to specialist endocrinology, physiology, and medical texts.

FAQ
Frequently Asked Questions
In current medical terminology for mammals, they are often used synonymously. Strictly speaking, 'thyrocalcitonin' specifies its origin in the thyroid gland, while 'calcitonin' is the general name for the hormone, which can be produced in other tissues in non-mammals.
Its primary function is to lower blood calcium levels by inhibiting the activity of osteoclasts (cells that break down bone), thereby reducing calcium release from bone into the bloodstream.
It is most relevant in conditions like hypercalcaemia (excess blood calcium), medullary thyroid carcinoma (a cancer of the C-cells that can overproduce it), and in the study of bone diseases like osteoporosis.
No, it is a highly specialised scientific term. An English learner would only encounter it in very specific academic or medical contexts, and it is not necessary for general language proficiency.
A polypeptide hormone secreted by the C-cells of the thyroid gland in mammals, which lowers blood calcium levels by inhibiting bone resorption.
Thyrocalcitonin is usually technical/scientific in register.
