THE ADENOHYPOPHYSIS, THYROTROPIN & THE REGULATION OF THYROXIN by Professor Fink

In this video lecture, Professor Fink reviews the role of the Hypothalamic Releasing Hormones on the Adenohypophysis (Anterior Lobe of the Pituitary Gland) in general, and then describes the Regulation of Thyroxin via TRH and Thyrotropin (TSH) in particular. Included in the detailed discussion is the Negative Feedback Loop involved in homeostatically maintaining circulating plasma Thyroxin levels. Reference is made to T4 & T3, the actions of Thyroxin, Hypothyroidism (Primary, Secondary & Tertiary), Hyperthyroidism, Cretinism, and the clinically-characteristic TSH (Thyrotropin) levels in Hypothyroidism.
