Thyrocyte Chief

Thyrocytes are auxiliary cells of the thyroid gland (thymus), serving as cellular producers of thyroid-stimulating hormone. It is they who “produce” the first thyrotropin and thereby “prepare” the thyroid gland for the further hormonal program of their organ. If they were not there, the thyroid gland simply would not be able to start working at full strength, since it would be “inhibited” by cells producing an inactive hormone. Thyroxine (the active form of the hormone), necessary for the functioning of both the body and organs, is actively synthesized exclusively by this tissue in the first days of life after birth. And despite the fact that the synthesis of hormones is synthesized mainly in the cells of the thyroid gland, the main role still belongs to the producing cells.

When is a functionally active gland called primary, and disaccharide-like pituitary-secreting tissue with the only function of promoting the formation of thyroid hormones is called secondary? It was more logical
