Does Thyroxine follow the Negative Feedback System? Why?

-Yes -This ensures that the Right amount of Thyroxine is present in the Blood stream -If it high, TSH from the Pituitary Gland is Inhibited ['Sucked'] which leads to Thyroxine Production stopping -If too low, TSH from the Pituitary Gland starts, which leads to Thyroxine Production Starting
