An additional hormone produced by the thyroid contributes to the regulation of blood calcium levels. Parafollicular cells produce calcitonin in response to hypercalcemia. Calcitonin stimulates movement of calcium into bone, in opposition to the effects of parathyroid hormone (PTH). However, calcitonin seems far less essential than PTH, as calcium metabolism remains clinically normal after removal of the thyroid, but not the parathyroids.
There are two important hormones. They are tyroxine and calcitonin.
The parafollicular cells (also called C cells) secrete the hormone calcitonin. Calcitonin is a weak hormone that helps in the regulation of calcium in some animals. In humans, calcitonin has only a minor role in calcium regulation.
The C cells of the thyroid gland produce calcitonin, a hormone that helps regulate calcium levels in the blood. Calcitonin works to decrease calcium levels by inhibiting bone breakdown and promoting calcium uptake by the bones.
Parafollicular cells of the thyroid gland produce calcitonin.
The thyroid secretes a hormone called thyroxine, which is a hormone.Thyroid is an endocrine gland.It produces thyroxine and calcitonin
The hormone is called as calcitonin. This hormone is secreted by the parathyroid glands.
Calcitonin is the hormone that lowers calcium levels.
Calcitonin
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
Calcitocin works with parathormone to regulate the calcium level of body. Parathormone rises the calcium level and calcitonin reduces it.
The parathyroid hormone is secreted directly from the parathyroid gland. The thyroid gland secretes calcitonin.
