To determine: The names of different thyroid hormones.
Introduction: Thyroid hormones are produced by the thyroid glands present in the front side of the trachea. The thyroid gland is an endocrine gland, and the secretions are released in the blood to reach the target cells. Iodine is a crucial mineral which is used by the thyroid gland as a precursor to produce thyroid hormones.
To determine: The name of the thyroid hormone that has the highest activity.
Introduction: Thyroid hormones are produced by the thyroid glands present in the front side of the trachea. The three different types of hormones produced by the thyroid gland are triiodothyronine (T3), thyroxine (T4), and calcitonin.
To determine: The region where thyroid hormone that has the highest activity is mostly produced.
Introduction: Thyroid hormones are produced by the thyroid. The three different types of hormones produced by the thyroid gland are triiodothyronine(T3), thyroxine(T4), and calcitonin. The highest concentration of thyroid hormone produced is T4 almost 80 % of the T4 is produced by the thyroid gland but the highest activity is shown by T3 hormone.
