Isthmus of the Thyroid Gland

Isthmus of the thyroid gland: function and diseases

The thyroid isthmus is a narrow section of the thyroid gland that connects its two lobes. It is located on the anterior surface of the trachea, below the thyroid cartilage. The isthmus of the thyroid gland performs an important function in the human body, but can also become the site of various diseases.

Function of the thyroid isthmus

The isthmus of the thyroid gland plays an important role in regulating metabolism in the body. It is the location of a number of cells that produce thyroid hormones - thyroxine and triiodothyronine. These hormones are involved in the regulation of metabolism, thermoregulation, growth and development of the body.

Diseases of the thyroid isthmus

The isthmus of the thyroid gland can become the site of various diseases, such as:

1. Hyperthyroidism. This is a condition in which the thyroid gland produces too many hormones, leading to increased metabolism, increased blood pressure, increased body temperature, increased heart rate and other symptoms.
2. Hypothyroidism. This is a condition in which the thyroid gland does not produce enough hormones, resulting in slow metabolism, fatigue, low body temperature, digestive problems and other symptoms.
3. Goiter. This is a disease in which the thyroid gland enlarges and forms a tumor. A goiter can be either diffuse, when the entire thyroid gland is enlarged, or nodular, when individual nodes form.
4. Thyroid cancer. Thyroid cancer can occur in both the thyroid lobes and the isthmus.

Diagnosis and treatment of diseases of the thyroid isthmus

Diseases of the thyroid isthmus can be detected by thyroid ultrasound, computed tomography, or magnetic resonance imaging. To clarify the diagnosis, a biopsy of thyroid tissue may be necessary.

Treatment for thyroid isthmus disease depends on the specific disease and may include medications, radioactive iodine, surgery, or a combination of these.

Conclusions The isthmus of the thyroid gland is an important part of the human body, responsible for the regulation of metabolism. However, the isthmus can also become the site of various diseases such as hyperthyroidism, hypothyroidism, goiter and thyroid cancer. To determine the diagnosis, various research methods are used, such as ultrasound, computed tomography and magnetic resonance imaging. Treatment for thyroid isthmus disease depends on the specific disease and may include medications, radioactive iodine, surgery, or a combination of these. It is important to see a doctor at the first symptoms of thyroid disease, as early treatment helps prevent the development of serious complications.

The isthmus of the thyroid gland (lat. isthmus g̦landulae thyreoidi) is an anatomical term that defines a section of the iron arch (jumper), normally of small width, connecting the anterior and posterior lobes of the thyroid gland. To the normal anatomy of this human organ, its structure and peculiarities of functioning in different representatives of the fauna and population of different regions of the Earth.
