Explanation:
Detailed explanation-1: -An important example of a negative feedback loop is seen in control of thyroid hormone secretion. The thyroid hormones thyroxine and triiodothyronine ("T4 and T3") are synthesized and secreted by thyroid glands and affect metabolism throughout the body.
Detailed explanation-2: -Positive and negative feedback mechanisms are two different types of feedback mechanisms. Positive feedback stimulates and increases hormone secretion. Negative feedback stops and inhibits the hormone from being produced.
Detailed explanation-3: -TRH-synthesis and release from these neurons are primarily under negative feedback regulation by thyroid hormone.
