NORMAL THYROID SIZE: THE THYROID GLAND


Normal Size Of The Thyroid Gland

The thyroid gland is one of the ten endocrine glands that control the functions of the body by producing chemicals (called hormones) into our blood stream. As the blood travels through the entire body, the hormones, which embody important messages from the brain, are transported to the different organs. These chemical codes in the thyroid gland allow the organs to carry out specific progressions like development of the body and reproduction.


The assigned function of the thyroid gland is the directive of body metabolism. Metabolism is the speed at which the body utilizes energy and the speed at which its tasks work. Because of this fundamental role, thyroid gland secretions have a direct control on growth and the performance of the nervous system.

The thyroid gland secretes the most important hormones tri-iodothyronine (T3), thyroxine (T4), and calcitonin. The hormone calcitonin is also called thyrocalcitonin, and it works in tandem with PTH, the parathyroid hormone, to control the level of calcium found in tissues and the bloodstream. When calcium levels in the blood rise elevated than normal, excess calcium is moved, by action of calcitonin, into the bones for storage.

The thyroid gland can be found at the facade of your neck, near the position where your two shoulder bones meet below the voice box (or larynx). The thyroid gland is soft and flexible, weighing a mere 15 to 25 grams. The thyroid gland becomes enlarged, however slightly, as a result of any disorder, and the changes will be more visible.
