Thyroid hormone is the hormone that controls your body’s metabolism, the process in which your body transforms the food you eat into energy. The two main hormones your thyroid releases — thyroxine (T4) and triiodothyronine (T3) — collectively make up thyroid hormone.
Thyroxine, also known as T4 and tetraiodothyronine, is the main hormone your thyroid gland releases into your bloodstream. Your thyroid also releases small amounts of triiodothyronine (T3). T4 and T3 work together and are commonly referred to as “thyroid hormone.”
Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. It plays vital roles in metabolism, heart and muscle function, brain development, and maintenance of bones.
Thyroxine (T4): This is the primary hormone your thyroid makes and releases. Although your thyroid makes the most of this hormone, it doesn’t have much of an effect on your metabolism. Once your thyroid releases T4 into your bloodstream, it can convert to T3 through a process called deiodination.
Follicular cells in the gland produce the 2 main thyroid hormones: Tetraiodothyronine (thyroxine, T4) Triiodothyronine (T3) These hormones act on cells in virtually every body tissue by combining with nuclear receptors and altering expression of a wide range of gene products.
The thyroid hormone is well known for controlling metabolism, growth, and many other bodily functions. The thyroid gland, anterior pituitary gland, and hypothalamus comprise a self-regulatory circuit called the hypothalamic-pituitary-thyroid axis.
Thyroxine plays a crucial role in heart and digestive function, metabolism, brain development, bone health, and muscle control. It affects almost all of the body's systems, which means proper thyroxine levels are vital for health.
Thyroid hormone induces effects on practically all nucleated cells in the human body, generally increasing their function and metabolism. Cardiac output, stroke volume, and resting heart rate increase through positive chronotropic and inotropic effects.
Measuring about 2 inches wide and weighing 20 to 60 grams, the thyroid's function is to make hormones that are vitally important to the body’s metabolism, growth, and development. The thyroid produces and releases two major hormones— thyroxine (T4) and triiodothyronine (T3) .
Thyroxine (referred to as T4) is a major player in your endocrine system. It is responsible for your metabolism, mood, and body temperature, among other things.
