. "Thyrotropic feedback control (TFC, a. k. a. pituitary-thyroid axis) in vertebrates controls the secretion of classical thyroid hormones (iodothyronines) by means of the control hormone TSH (and possibly additional hormones like thyrostimulin). As thyroid hormones play an important role for metabolism, growth and differentiation, exact regulation of thyroid hormone levels is vital for most organisms."@en . . . .
