The hormone epinephrine binds to ß adrenergic receptors on smooth muscle cells of the bronchioles, causing them to dilate (increase in diameter). Thyroid hormone is essential for the synthesis of ß adrenergic receptors; therefore, in the absence of thyroid hormone, epinephrine cannot trigger bronchodilation. This concept if known as .
