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 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.
Parafollicular cells of the thyroid gland produce 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
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.
The main hormone produced here is thyroxine, which controls metabolism in our cells.
