High thyroxine levels inhibit the release of TRH from the hypothalamus, reducing TSH production and consequently lowering thyroxine levels.
Yüksek tiroksin seviyeleri, hipotalamus'tan TRH salınımını engelleyerek TSH üretimini azaltır, böylece tiroksin seviyeleri düşer.

| Back | The release of TRH from the hypothalamus is inhibited which reduces production of TSH so thyroxine levels fall. |
