Mechanisms of action of thyroid hormones
WebYour thyroid’s main job is to control the speed of your metabolism (metabolic rate), which is the process of how your body transforms the food you consume into energy. Your thyroid releases the following hormones: Thyroxine (T4). Triiodothyronine (T3). Reverse triiodothyronine (RT3). Calcitonin. WebThyroid hormone increases the metabolic rate of cells of all tissues in the body. In the fetus and newborn, thyroid hormone is important for the growth and development of all tissues including bones and the brain. In adults, thyroid hormone helps to maintain brain function, food metabolism, and body temperature, among other effects.
