The thyroid produces several hormones, such as thyroxine (T4) and triiodothyronine[?] (T3), and contains the parathyroid glands[?], which produce calcitonin[?].
When the thyroid is removed, oral synthetic thyroid hormones are usually prescribed to prevent the most serious manifestations of the resultant hypothyroidism.
