- Sainmhíniú any small readily diffusible intracellular mediator, whose concentration inside the cell changes rapidly on receptor activation, and which thus regulates the activity of other target signalling molecules Tagairt "COM-Terminology Coordination, based on:Kimball's Biology Pages, Second Messengers (27.4.2020)"
- Nóta The term second messenger was coined upon the discovery of these substances in order to distinguish them from hormones and other molecules that function outside the cell as “first messengers” in the transmission of biological information. Many second messenger molecules are small and therefore diffuse rapidly through the cytoplasm, enabling information to move quickly throughout the cell.
