Atoms are the smallest building blocks of elements having the same chemical and physical properties of that specific element. Atoms combine together with the help of electrons, to form a little more complex entity like the molecules, crystals, liquids etc. Some molecules combine together to form a more complex entity like the DNA which is the most complex molecule. The whole universe is made out of these simple building blocks, including the human body.

Answer:
Hypothalamus and anterior pituitary gland.
Explanation:
Lower levels of T3 and T4 in the blood or lower metabolic rate serve as signal and stimulate the release of thyrotropin-releasing hormone (TRH) from the hypothalamus. The TRH stimulates the anterior pituitary gland to release thyroid-stimulating hormone (TSH) which in turn makes the thyroid gland to release the thyroid hormones.
The elevated levels of thyroid hormones inhibit the release of TRH from the hypothalamus and that of TSH from the anterior pituitary gland.
Hence, the cells of hypothalamus and anterior pituitary gland would be inhibited by the binding of thyroid hormone to regulate the release of these hormones by a negative feedback mechanism.
