What is the purpose of hormone calcitonin function?

Answer 1

Calcitonin is a 32-amino acid linear polypeptide hormone that is produced in humans primarily by the parafollicular cells (also known as C-cells) of the thyroid, and in many other animals in the ultimobranchial body.[2] It acts to reduce bloodcalcium (Ca2+), opposing the effects ofparathyroid hormone (PTH).[3] It has been found in fish, reptiles, birds, and mammals. Its importance in humans has not been as well established as its importance in other animals, as its function is usually not significant to regulation of normal calcium homeostasis.[4]

Answer 2

T2 and T1.

The basic compounds with only one iodine molecule (T1) or two iodine molecules (T2) are also secreted into the blood circulation although they have never traditionally been considered as significant as T3 or T4.

Normally, the thyroid gland secretes an abundance of T4 along with smaller amounts of T3 and even smaller amounts of tyrosine, T1 and T2.

Answer 3

it promotes absorption of calcium into the bones, thus lowering blood calcium.

Answer 4

It lowers levels of calcium by inhibiting osteoclast activity and incresing excretion of calcium at the kidneys.

Answer 5

Calcitonin is a large peptide hormone released bu the thyroid gland. Calcitonin slightly decreases blood calcium by decreasing osteoclast activity and number.

Answer 6

It is produced by thyroid.It reduces calcium and phosphate level of body.
