Thyrvcalcitonin, Calcitonin

Thyrvcalcitonin and calcitonin are hormones produced by the parafollicular cells of the thyroid gland. These hormones play an important role in regulating calcium and phosphate levels in the blood.

Calcitonin was discovered in 1962 and was the first hormone identified in the parafollicular cells of the thyroid gland. The main function of calcitonin is to reduce calcium levels in the blood by inhibiting bone resorption, a process in which bone tissue is broken down and calcium is released into the blood. Calcitonin also stimulates the kidneys to remove calcium from the blood, reducing its concentration.

Thyrocalcitonin is a more active form of calcitonin and has a large number of amino acid residues. This hormone also helps reduce calcium and phosphate levels in the blood, but its effect is more intense than that of calcitonin. Thyrocalcitonin is often used medically to treat hypercalcemia, a condition in which calcium levels in the blood are too high. It is also used to treat Paget's disease, a condition in which bones become weaker and more prone to fracture.

Unlike calcitonin, which lowers blood calcium levels, parathyroid hormone (PTH) increases calcium levels by stimulating bone resorption and increasing calcium excretion from the kidneys. PTH and calcitonin are antagonists, meaning they have opposite effects on blood calcium levels.

Thyrocalcitonin and calcitonin are important hormones that regulate calcium levels in the blood. Their use in medicine can reduce calcium levels in the blood and reduce the risk of developing certain diseases.

Thyrocalcitonin and calcitonin are two important hormones that are produced in the human body and play an important role in regulating the level of calcium and phosphorus in the blood. Both hormones are produced by parafollicular cells in the thyroid gland, but have different functions.

Thyrocalcitonin is a more active hormone that helps reduce calcium and phosphate levels in the blood. It is produced during hypercalcemia, which can be caused by various diseases such as thyroid cancer, Graves' disease and Paget's disease. Thyrocalcitonin is also used to treat these diseases by injection into the body.

Calcitonin, on the other hand, is a less active hormone and is produced in response to increased calcium levels in the blood. This hormone helps regulate calcium levels in the body, preventing excess accumulation in bones and other tissues. Calcitonin is produced by parathyroid cells, which are found in the parathyroid gland.

It is important to note that both hormones play an important role in maintaining bone health and regulating calcium and phosphorus metabolism. However, thyrocalcitonin is only used to treat certain diseases, while calcitonin plays a more important role in regulating calcium levels in the body and can be used to prevent and treat bone diseases.

Thyrocalcitonin and calcitonin are two hormones produced in the parafollicular cells of the thyroid gland. They have similar functions, but differ in their structure and action.

Thyrocalcitonin is a hormone that lowers calcium and phosphate levels in the blood, which helps fight hypercalcemia and Paget's disease. It is administered by injection to patients suffering from these diseases.

Calcitonin, on the other hand, is a parathyroid hormone that regulates calcium levels in the blood. It is also involved in the regulation of phosphorus and magnesium metabolism. Calcitonin is produced by the parafollicular cells of the parathyroid glands and is released into the blood, where it binds to receptors on the surface of the cells.

Parathyroid hormone (PTH) is produced by the parathyroid glands and also affects calcium levels in the body. It stimulates bone resorption and increases calcium levels in the blood plasma.

Thus, thyrocalcitonin and parathyroid hormone work together to maintain the balance of calcium and phosphorus in the body. However, each of them has its own specific role and can be used depending on the specific needs of the body.
