Cellular Signaling Mechanisms

Cellular signaling mechanisms are the ways in which cells communicate with each other to coordinate their activities. Cells use chemical signals, like hormones or neurotransmitters, which bind to specific receptors on other cells, triggering a response. This process can control various functions, such as growth, immune responses, or metabolism. Think of it as a phone call: one cell "calls" another by sending a signal, and the receiving cell "answers" by carrying out specific actions. This intricate communication ensures that cells work together harmoniously, maintaining the body’s health and responding to changes in the environment.
