The hypothalamus and the pituitary gland, which are located in the brain, help control the thyroid gland. The hypothalamus releases thyrotropin-releasing hormone (TRH), which stimulates the pituitary gland to release thyroid-stimulating hormone (TSH).
What function is regulated by thyroid hormones?
The thyroid gland produces hormones that regulate the body’s metabolic rate controlling heart, muscle and digestive function, brain development and bone maintenance. Its correct functioning depends on a good supply of iodine from the diet.
What hormones does the thyroid control?
Your thyroid makes 2 main hormones – triiodothyronine (T3) and thyroxine (T4). Adequate amounts of iodine (a chemical element that’s an essential part of our diet) are needed for the thyroid to be able to make these hormones. Another hormone that’s produced in your thyroid gland is called calcitonin.
How is the thyroid gland regulated?
The thyroid gland is regulated by thyrotropin releasing hormone (TRH) and thyroid stimulating hormone (TSH). In addition to TRH/TSH regulation by TH feedback, there is central modulation by nutritional signals, such as leptin, as well as peptides regulating appetite.
What are the 3 thyroid hormones?
The thyroid gland produces three hormones: Triiodothyronine, also known as T3. Tetraiodothyronine, also called thyroxine or T4. Calcitonin.
What are the major effects of thyroid hormones in the body?

What does a thyroid function test show?
The test, called a thyroid function test, looks at levels of thyroid-stimulating hormone (TSH) and thyroxine (T4) in the blood. Doctors may refer to this as “free” T4 (FT4). A high level of TSH and a low level of T4 in the blood could mean you have an underactive thyroid.
