The thyroid gland is located in front of the trachea. The thyroid gland resembles the butterfly, which has a two-sided, red-brown, two-part butterfly. The thyroid gland also contains cystic cells, which are special cells in the lining of the thyroid gland. The thyroid gland is a triiodothyronine and a thyroxine. The thyroid gland is an endocrine glands that work directly into the bloodstream without the need for means and means to transport it. The thyroid gland works mainly on the secretion of thyroid hormone One of two types:
- Type I: one-third of the thyroid, which is converted to thyroxine at the desired tissue.
- Type II: Thyroxine This hormone is the primary and primary hormone in the thyroid gland.
Thyroxine is produced and secreted by the axis under the pituitary bed because the area under the bed in the brain called the hypothalamus works to secrete the hormone that releases thyroidine, which works in the pituitary gland. The pituitary gland secrete the thyroid hormone, which secrete and produce thyroxine.
The amount of thyroxine in the blood decreases or decreases. When the amount of thyroxine decreases in the blood, pituitary hormones increase. The higher the amount of thyroxine in the blood, the lower the pituitary gland hormones. This process is called negative feedback. The function and profession of thyroxine is the normal level of hormones To perform its work in the blood to the fullest.
Thyroid hormones may increase the secretion of oxygen in the tissues responsible for the basic consumption of oxygen, such as the heart, muscles, kidneys, and liver. Thyroid hormones also increase protein synthesis in almost all parts of the body .
Hypothyroidism
Many people suffer from hypothyroidism. The main and most common cause of the disease is iodine deficiency, along with other factors such as hypothyroidism, pituitary hormones, and many hypothyroidism due to inflammation of the gland Thyroid, or after surgery which would cause hypothyroidism.
Increased thyroid secretions
Some people suffer from an increase in thyroid secretions which are produced for several reasons:
- Inflammation of the thyroid gland, such as inflammation of the thyroid gland, causes inflammation of the thyroid gland, which causes an increase in thyroid secretions, which may develop in its condition and cause hypothyroidism.
- Excessive intake of drugs containing thyroid hormones.
- Many women develop increased thyroid secretion after birth.
- Graves disease.
