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]

The hormone that works with the parathyroid hormone to regulate calcium levels in the blood and tissues is?

Calcitonin is the hormone that works with parathyroid hormone to regulate calcium levels in the blood and tissues. Calcitonin helps to lower blood calcium levels by promoting calcium deposition in bones.


What hormone pairs are antagonists that regulate blood calcium ion levels?

Parathyroid hormone (PTH) and calcitonin are antagonistic hormones that regulate blood calcium ion levels. PTH increases blood calcium levels by promoting calcium release from bone and absorption from the intestines, while calcitonin decreases blood calcium levels by inhibiting bone resorption.


What directly antagonizes the effect of 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.


What hormone exerts antagonistic action to PTH or parathyroid hormone?

Calcitonin is a hormone that exerts antagonistic action to parathyroid hormone (PTH). Calcitonin helps regulate calcium levels in the blood by promoting calcium deposition in the bones, thus reducing blood calcium levels, whereas PTH increases blood calcium levels by promoting calcium release from bones.


What hormone is secreted by cells of the thyroid gland works with the parathyroid hormone to regulate the calcium levels in the blood and tissues?

Calcitonin is the hormone secreted by cells of the thyroid gland that works with parathyroid hormone to regulate calcium levels in the blood and tissues. Calcitonin helps to lower blood calcium levels by inhibiting the activity of osteoclasts, which are cells that break down bone tissue and release calcium into the bloodstream.

Calcitonin!


The hormone that has the opposite function of calcitonin is?

The hormone that has the opposite function of calcitonin is parathyroid hormone (PTH). While calcitonin decreases blood calcium levels by promoting its deposition in bones, PTH increases blood calcium levels by stimulating calcium release from bones, absorption in the intestines, and reabsorption in the kidneys.


What hormone causes a decrease in blood calcium levels?

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


The hormone that is that antagonist of calcitonin is?

The opponent or antagonist of calcitonin is the parathyroid hormone. The hormone is released from as polypeptide from the parathyroid glands.

calcitonin


Name a hormone secreted by the thyroid gland that acts to lower blood calcium?

Calcitonin is the hormone that lowers calcium levels.


What hormone is released when blood calcium levels are too high?

When blood calcium levels are too high, the hormone calcitonin is released. Calcitonin helps regulate calcium levels by promoting its deposition into bone tissue, thus lowering blood calcium levels.

What hormone controls the metabolism of calcium?

Parathyroid hormone (PTH) controls the metabolism of calcium in the body by increasing calcium levels in the blood through actions on the kidneys, bones, and intestines.
