Endocrine gland hormones at target cells "Permissiveness" is the situation in which a hormone cannot exert its full effects without the presence of another hormone. "Synergism" occurs when two or more hormones produce the same effects in a target cell and their results are amplified. "Antagonism" occurs when a hormone opposes or reverses the effect of another hormone. The endocrine glands belong to the body's control system. The hormones which they produce help to regulate the functions of cells and tissues throughout the body. Endocrine organs are activated to release their hormones by humoral, neural or hormonal stimuli. Negative feedback is important
