Thyroxine (T4) is produced by the thyroid gland under regulation from the hypothalamus and pituitary gland. The feedback loop signals to the hypothalamus in to release thyrotropin-releasing hormone, which then stimulates the pituitary gland to release the thyroid stimulating hormone.
What are the three hormones produced by the thyroid gland?
The thyroid gland produces three hormones: Triiodothyronine, also known as T3. Tetraiodothyronine, also called thyroxine or T4. Calcitonin.
What are the T3 and T4 hormones?
The thyroid produces a hormone called triiodothyronine, known as T3. It also produces a hormone called thyroxine, known as T4. Together, these hormones regulate your body’s temperature, metabolism, and heart rate.
What is the function of T4?
The thyroid is a small, butterfly-shaped gland located near the throat. Your thyroid makes hormones that regulate the way your body uses energy. It also plays an important role in regulating your weight, body temperature, muscle strength, and even your mood. Thyroxine, also known as T4, is a type of thyroid hormone.

TSH normal values are 0.5 to 5.0 mIU/L. Pregnancy, a history of thyroid cancer, history of pituitary gland disease, and older age are some situations when TSH is optimally maintained in different range as guided by an endocrinologist. FT4 normal values are 0.7 to 1.9ng/dL.
What range is normal for thyroid?
Normal test range for an adult: 0.40 – 4.50 mIU/mL (milli-international units per liter of blood). T4: thyroxine tests for hypothyroidism and hyperthyroidism, and used to monitor treatment of thyroid disorders. Low T4 is seen with hypothyroidism, whereas high T4 levels may indicate hyperthyroidism.
Which disease is caused by deficiency of thyroxine in adults?
The body can also contain insufficient thyroxine, which is known as hypothyroidism. If it happens while the person is young, low thyroxine levels contribute to development problems.

What is the difference between T3 and T4 thyroid hormones?
Difference Between T3 and T4. The main difference between T3 and T4 is that the T3 refers to the active thyroid hormone whereas the T4 refers to the precursor of the thyroid hormone produced by the thyroid gland. Furthermore, T4 is converted into T3 by an enzyme called iodothyronine deiodinase, mainly in the liver.
