Iodine is necessary for which gland to make the thyroxine hormone?  

The correct answer is Thyroid gland.

Key Points

• The thyroid gland requires iodine to produce thyroxine (T4) and triiodothyronine (T3) hormones.
• Thyroxine (T4) is the primary hormone produced by the thyroid gland.
• Iodine deficiency can lead to hypothyroidism and goiter.
• The thyroid gland is located in the neck, below the Adam's apple.
• Thyroid hormones regulate the body's metabolic rate, heart and digestive functions, muscle control, brain development, and bone maintenance.

Additional Information

• Hypothyroidism:
  • A condition where the thyroid gland does not produce enough thyroid hormones.
  • Symptoms include fatigue, weight gain, cold intolerance, and depression.
• Hyperthyroidism:
  • A condition where the thyroid gland produces excessive amounts of thyroid hormones.
  • Symptoms include weight loss, heat intolerance, increased appetite, and anxiety.
• Goiter:
  • An abnormal enlargement of the thyroid gland.
  • Often caused by iodine deficiency.
• Iodine:
  • An essential element required for the synthesis of thyroid hormones.
  • Found in foods such as seafood, dairy products, grains, and iodized salt.
• Thyroid Function Tests:
  • Blood tests used to measure levels of T3, T4, and thyroid-stimulating hormone (TSH).
  • Help diagnose thyroid disorders and monitor treatment efficacy.
