calcitonin
The thyroid gland secretes both of these. Thyroxine or T4 is the most prevalent secretion of the thyroid - it is the inactive form of tri-iodothyronine (T3) which is important for regulation of metabolism. T3 and T4 are secreted by the follicular cells. Calcitonin is secreted by the parafollicular cells of the thyroid gland and acts to decrease blood calcium levels.
in the parafollicular cells of the thyroid gland
Parafollicular cells of the thyroid gland
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
Thyroxine is secreted by the thyroid gland, while calcitonin is primarily secreted by the thyroid gland's C cells (parafollicular cells). Thyroxine is involved in regulating metabolism, growth, and development, while calcitonin helps regulate calcium levels in the blood by promoting calcium deposition in bones.
The thyroid gland is composed of follicles lined by follicular cells that produce thyroid hormones (T3 and T4). These follicles are filled with colloid, which stores thyroid hormone precursor thyroglobulin. The gland also contains parafollicular cells (C cells) that produce calcitonin.
Thyroid secretion hormone is secreted by the thyrotrope cells in d anterior pituitary gland
No, calcitonin is not secreted by the pituitary gland. It is a hormone produced by the parafollicular cells of the thyroid gland. Calcitonin helps regulate calcium levels in the body by inhibiting the breakdown of bone, which leads to a decrease in blood calcium levels.
Thyroxine, or 3,5,3',5'-tetraiodothyronine - T4, a form of thyroid hormones is the major hormone secreted by the follicular cells of the thyroid gland.
The thyroid gland has certain cells known as parafollicular cells (AKA C cells) that secrete a hormone known as calcitonin that can decrease blood calcium levels.
The Anterior pituitary gland secretes the thyroid stimulating hormone (TSH) this targets the thyroid gland, stimulating the release of thyroid hormones. Thyroid-stimulating horomone(TSH) is secreted by the Pitutary gland( Specifically thyrotrope cells of Anterior pitutary gland). TSH regulates thyroid gland.
Parafollicular cells of the thyroid gland produce calcitonin.
