Antagonistic interactions occur when both divisions of the ANS have opposing effects on the same target cells that express both types of receptors, for example, the sympathetic system increasing heart rate while the parasympathetic system decreases it.
1. Both divisions may have opposing effects on the same target cells which expresses both types of receptor <div>Ex: Sympathetic increases HR and parasymp decreases HR</div>
