The four ways in which the adrenaline signal to the heart is terminated. Concept Introduction: The hormone adrenaline is secreted from the adrenal gland located above the kidney. The receptors for this hormone are present in various tissues and glands of the body. The release of the hormone in the blood causes it to be transported to the receptors present in the various cells of the body. The binding of this hormone ligand to the receptor causes the activation of the cell signaling mechanism inside the cell. The hormone reaches the receptors in the heart and stomach. The binding of this ligand with the G cell receptor complex causes the contraction of the heart muscles.
