cell signaling networks

Cell signaling networks are the ways cells communicate and coordinate with each other. When a cell detects a specific signal—like a hormone or a chemical—it triggers a series of events inside that cell, similar to passing messages along a chain. These signals help cells respond appropriately, such as growing, dividing, or defending against threats. The network involves various molecules acting as messengers, receptors, and enzymes, working together smoothly. Overall, cell signaling ensures that cells respond correctly to their environment, maintaining health and proper function within the body.
