Low thyroxine levels stimulate TRH production from the hypothalamus, which stimulates the pituitary gland to release TSH, which in turn stimulates the thyroid gland to release thyroxine.
Düşük tiroksin seviyeleri, hipotalamus'tan TRH üretimini uyarır, bu da hipofiz bezini TSH salgılamaya teşvik eder ve bu da tiroit bezini tiroksin salgılamaya teşvik eder.
