The role of the thyroid gland is to make, store and release thyroid hormones. These hormones have a large impact on your health as they are involved in many important cell functions. This includes everything from growth of the body and brain, to the release of other important hormones, and even how energized you feel. The thyroid is so important that it has a special communication system with the brain in order to make sure that the correct amount of hormone is being made and released.
The thyroid gland uses iodine to produce thyroid hormones -- primarily thyroxine (T4) and triiodothyronine (T3). T4 gets converted into T3 (a more active form) in the blood. Thyroid hormones regulate our metabolic rate and affect weight and energy level. The thyroid also produces calcitonin, which contributes to calcium balance. Thyroid hormone production is regulated by a feedback system involving the pituitary gland (a small gland at the base of the brain).

Background: What is the thyroid?Helpful? 2 people found this helpful.
Julia Schlam Edelman, OBGYN (Obstetrics & Gynecology), answeredThe thyroid is a soft, butterfly-shaped gland located in the neck, in front of the trachea (windpipe). The thyroid gland regulates metabolism, telling the body how fast to think and move and process food and waste. Thyroid function affects hair health, including breakage, texture, rate of growth, and rate of loss. It affects nail health and growth. It affects reflexes (which may become too fast or too slow) and the quality of sleep.Helpful? 1 person found this helpful.
Mehmet Oz, MD, Cardiology (Cardiovascular Disease), answeredLocated at the base of the neck on both sides, the butterfly-shaped thyroid gland produces thyroid hormone after receiving chemical signals from the pituitary. The main function of the thyroid hormone is to regulate the metabolism of your cells-that is, the chemical changes in your cells that cause them to live, grow, and die.
You can think of your metabolism a little bit like your utility bill. From neighbor to neighbor, no two utility bills are alike. Some people keep their AC at 76; some keep it at 68. Some take 20-minute showers; some hop in and out in 20 seconds. We all use and consume energy a little bit differently in our homes, and we all use and consume it a little differently in our bodies. And that plays a key role in weight management; some of metabolism is genetic, in that you're pre-disposed to have a quick-working metabolism or a slow-churning one. That regulation comes in part from your thyroid hormone.
