When the effects of one hormone reinforce the activity of another hormone on the same target cell the interaction is said to be?

When the effects of one hormone reinforce the activity of another hormone on the same target cell, the interaction is said to be synergistic. In a synergistic interaction, the combined effect of the hormones is greater than the sum of their individual effects, enhancing the biological response in the target tissue. This interplay is crucial for regulating various physiological processes in the body.
