WebSep 1, 2012 · The hypothalamic-pituitary-thyroid (HPT) axis is a classical example of how a neuroendocrine system regulates distinct functions of an organism both during development ( 1, 2) and in adult life in response to a variety of challenges, presumably improving its chance of success. The hypothalamic–pituitary–thyroid axis (HPT axis for short, a.k.a. thyroid homeostasis or thyrotropic feedback control) is part of the neuroendocrine system responsible for the regulation of metabolism and also responds to stress. As its name suggests, it depends upon the hypothalamus, the pituitary … See more 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 See more Standard procedures cover the determination of serum levels of the following hormones: • TSH (thyrotropin, thyroid stimulating hormone) • Free T4 • Free T3 See more • Dietrich J W, Tesche A, Pickardt C R, Mitzdorf U (2004).
