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.

Thyroid hormones are two hormones produced and released by the thyroid gland, triiodothyronine (T 3) and thyroxine (T 4). They are tyrosine-based hormones that are primarily responsible for regulation of metabolism. T 3 and T 4 are partially composed of iodine, derived from food. [2]

Your thyroid is an important endocrine gland that makes and releases hormones. Your thyroid's main job is to control your metabolism — how your body uses energy.

2023年6月5日 · 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.

2022年1月24日 · Parathyroid hormone is connected to blood calcium levels in the bones, intestines and kidneys. Parathyroid hormone comes from four parathyroid glands in the neck, just behind the thyroid. These glands receive feedback from blood calcium levels to determine when they need to secrete the hormone.

2023年3月13日 · Thyroid hormones induce 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.

2025年1月17日 · What is Thyroid Gland? The thyroid gland is an important hormone-producing organ in the front of the neck, just below the Adam’s apple. This gland is very important for keeping the body’s metabolism running smoothly because it makes thyroid hormones like calcitonin and thyroxine (T4) and triiodothyronine (T3).

2024年10月4日 · 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). These hormones help to regulate many crucial bodily functions such as:

Thyroid hormone is required for normal brain and somatic tissue development in the fetus and neonate, and, in people of all ages, thyroid hormone regulates protein, carbohydrate, and fat metabolism. T4 has minimal hormonal activity, but its long half-life (8 days) serves as a reservoir or prohormone for T3.

Thyroid hormones are hormones produced by the thyroid gland, which is located in the neck. The two thyroid hormones are thyroxine (T4) and triiodothyronine (T3); with T3 having the more active role in metabolic activities.
