Thyroid gland and hormones regulations

The thyroid is a gland located in the neck in front of the trachea, whose function is the production and secretion of thyroid hormones (T3 and T4).

In turn, thyroid function is controlled by the hypothalamus and the pituitary gland of the brain: the hormone TRH stimulates the pituitary gland and it secretes the hormone TSH, which travels through the blood to the thyroid and regulates its function.

On the other hand, thyroid hormones exert a negative regulation on the hypothalamus and pituitary gland, inhibiting the secretion of TRH and TSH.
