Hypothalamic–pituitary–thyroid axis control over the hypothalamus as well as anterior pituitary, thus controlling the release of both TRH from hypothalamus and TSH from anterior pituitary gland. The HPA, HPG, and HPT axes are three pathways in which the hypothalamus and pituitary direct neuroendocrine function. Thyroid homeostasis results from a multi-loop feedback system that is found in virtually all higher vertebrates. Proper function of thyrotropic feedback control is indispensable for growth, differentiation, reproduction and intelligence. Very few animals (e.g. axolotls and sloths) have impaired thyroid homeostasis that exhibits a very low set-point that is assumed to underlie the metabolic and ontogenetic anomalies of
Price controls larger incomes policy package also employing wage controls and other regulatory elements. Although price controls are sometimes used by governments, economists usually agree that price controls don't accomplish what they are intended to do and are generally to be avoided. For example, nearly three-quarters of economists surveyed disagreed with the statement, "Wage-price controls are a useful policy option in the control of inflation." The Roman Emperor Diocletian tried to set maximum prices for all commodities in the late 3rd century AD but with little success.
