The thyroid has one main function within the body of the endocrine system, and that is the regulation of the body's metabolism. Metabolism is the transformation of oxygen and calories to energy. And to do so, the thyroid have thyroid hormones. This is a hormone that is all tissues in the body increase in its cellular activity. In this article I will discuss how thyroid hormone is produced and shared problems.
The thyroid is the grate thyroid gland in the neck. It is located in the front part of the neck under the skin and muscle layers, familiar in a region known as the "Adams Apple. It has a butterfly shape and form part of its winged, cloth, wrap around each side of the trachea. Each cloth is then used with a narrow band of thyroid tissue, the so-called isthmus. The thyroid, even if the currently grate gland in the neck, is also one of the smallest glands in the body, weighing less than an ounce. The exact function of the thyroid is iodine, which is in many foods, and convert it into thyroid hormones. The two thyroid hormones produced are Thryoxine (T4) and triiodothyronine (T3). Thyroid cells are the only cells in the body can absorb iodine. They combine with the amino acid tyrosine to make T3 and T4. Then they are in the bloodstream, where they are transported, all over the body to control metabolism. The thyroid cells are crucial in the function of the body, because each cell depends on thyroid cells to regulate the thyroid metabolism.
Disorders are very common in today's society. There are four basic categories in which you find thyroid problems:
- hormone production (too much or too little: hyperthyroidism, hypothyroidism)
- problems due to increase growth the thyroid gland in the neck
- caused the compression of important structures in the neck.
- The formation of nodules or nodes in the thyroid (mass)
- cancer of the thyroid
When hormones regulate our Metabolism, they are regulating many things, such as how many calories we burn, how warm we feel and how much we weigh. It also has a direct impact on body organs like heart, which suggests faster and harder under the influence of hormones. In a healthy person, the thyroid is exactly the right amount of T3 and T4, that the body needs to regulate the metabolism. Hyperthyroidism is a condition of results from the activity of the thyroid, which means that the thyroid gland produces a surplus of hormones. There are many different causes of hyperthyroidism, but most of the symptoms are the same (symptoms are what the patient feels or announcements. Characters are what the doctor can detect or measure). Some of these symptoms are shortness of breath, insomnia, fatigue, light or absent menstrual cycles, heat intolerance, and nervousness. Cancer of the thyroid, where nodes or masses form of thyroid itself.
Therefore we can conclude that an insufficient production of thyroid hormones in the context of primary endocrine secretion of the thyroid gland, can cause many problems such as cellular differentiation, growth and metabolism.
