The effect of thyroid hormone on epinephrine's actions is a mechanism known as permissiveness.
Permissiveness is a relationship between hormones when the presence of one hormone is required in order to allow a second hormone to exert its full effects. Thyroid hormones have a possibility to increase the number of epinephrine receptors on the target cell.
