Everyone should be reminded that the thyroid gland is a very important part of the human body. Once a thyroid disease occurs, it must be treated as soon as possible. Any disease should not be delayed. In addition, many people do not know the structure of the thyroid gland, such as what the thyroid duct is. Let's take a closer look below.

What does the thyroid gland do?

The thyroid gland is the largest endocrine gland in the human body. It is located in the neck as a thin layer, under the thyroid cartilage and just in front of the third and fourth cartilage rings of the trachea. It consists of two side lobes and an isthmus. It is commonly known as a hibernating butterfly. Where is this butterfly hiding? Normally most people do not know where the thyroid gland is located, but most people are familiar with "thick neck disease". In fact, "thick neck disease" is an enlarged thyroid gland, which tells that the thyroid gland is located in the neck. To be more specific, you can feel the "Adam's apple" that we usually talk about. The thyroid gland is located about 2 to 3 centimeters below the "Adam's apple" and can move up and down with it when you swallow.

The thyroid gland (Latin: Glandulathyr(e)oidea; English: Thyroid) is a very important gland in vertebrates and an endocrine organ. In mammals it is located below the thyroid cartilage in the neck, on both sides of the trachea. The human thyroid gland is shaped like a butterfly and is like a shield, hence the name. The thyroid gland controls how quickly energy is used, makes proteins, and regulates the body's sensitivity to other hormones. The thyroid gland regulates these responses by making thyroxine, triiodothyronine (T3) and thyroxine, also known as tetraiodothyronine (T4). Both regulate metabolism, growth rate, and regulate other body systems. T3 and T4 are synthesized from iodine and tyrosine. The thyroid gland also produces calcitonin, which regulates the balance of calcium in the body - Chengdu Zhongke Thyroid Clinic.

It is a very important gland in vertebrates and belongs to the endocrine organ. In mammals it is located below the thyroid cartilage in the neck, on both sides of the trachea. The human thyroid gland is shaped like a butterfly and like a shield, hence the name. With the development of society and the continuous improvement of living standards, the incidence of thyroid disease among women is increasing. According to statistics, the rate is increasing by 0.3% each year. The thyroid gland is the largest endocrine gland in the human body. It is a thin layer located under the thyroid cartilage and close to the trachea.

The third and fourth cartilage rings are located in front of each other and are composed of two side lobes and the isthmus. The average weight is about 20-25g, which is slightly larger and heavier in females. Behind the thyroid gland are four parathyroid glands and the recurrent laryngeal nerve. The blood supply is mainly from four arteries, namely the superior and inferior thyroid arteries, so the thyroid gland has a rich blood supply. The gland is innervated by the sympathetic nerves of the cervical sympathetic ganglia and the vagus nerve.
