Second messengers are molecules that relay the signals received at receptors on the cell surface to target molecules in the cytosol or nucleus. This Pharmacology second messenger system/ Pharmacodynamics quiz is perfect for helping you see just how much you know about second messengers and how they achieve their function. Give it a shot and see how high your score is.
